What is the best translation and localization software in 2026?
A freelance translator, a team shipping an app in eight languages and a company translating contracts all type the same search. They need three different tools.
Search for "translation software" and you get DeepL, Crowdin, Trados and Google Translate on one list, often written by one of those vendors ranking itself first. Those tools don't do the same job. So this page splits them into three families before ranking anything.
CAT tools (computer-assisted translation) are for translators and agencies: the text is cut into segments, every approved sentence goes into a translation memory, and a termbase enforces the client's vocabulary. Localization platforms are for product teams: they manage the string files behind an app or website (JSON, XLIFF, .po) and sync with Git, Figma and your CMS. Machine translation is for everyone else: drop in a document, get it back translated in seconds.
The short answer. Phrase is the best overall pick because one account covers CAT and software localization, starting at $27 a month on the Freelancer plan. memoQ translator pro is the most complete desktop CAT tool for a freelancer, at $436 a year. Crowdin has the most generous entry point for product teams, with a free plan and unlimited translators on paid plans. Lokalise is the most polished localization platform, if you read the renewal terms. Smartcat fits teams that want AI translation with unlimited users.
What most roundups skip is the billing unit. Characters, hosted words, strings, MTUs, Smartwords: every vendor counts differently, and the unit is what blows up an invoice. We pulled each one from the official pricing pages.
The ranking is editorial: a sponsored placement is always labeled on its card, and no affiliate link changes a score.
Three tool families, three different jobs
Answer one question: what are you translating, and who does the work? That puts you in a family. Tools from one family don't replace tools from another.
You translate for clients: CAT tools
You're a freelance translator or you run an agency. Clients send Word, InDesign or XLIFF files and expect their terminology. You need translation memory, a termbase and QA checks. Look at memoQ translator pro, Phrase (Freelancer plan), Trados Studio, or OmegaT if your budget is zero.
You ship an app or site: localization platforms
You're on a product team. Your copy lives in string files and changes every release. You need a platform wired into your Git repo, invited translators and screenshots for context. Look at Crowdin, Lokalise, Phrase Strings or Smartcat. For a marketing site or a store, a website translation plugin is faster.
You need to understand or send fast: machine translation
You're translating a contract you received, an email, a deck. Nobody reviews segment by segment. You need an accurate engine, a glossary and a written promise that your text won't train a model. DeepL Pro is the usual pick here.
- You deliver translations to clients: CAT tool.
- Your copy sits in JSON, XLIFF or .po files: localization platform.
- You want a multilingual website without a developer: website translation plugin.
- You translate documents to read or send them: machine translation.

The top 5 translation tools compared
The ranking serves three readers: the freelance translator, the product team localizing an app or site, and the company translating its own documents. Every ranked tool shows a public US dollar price on its official page. Tools priced only in euros, or without a readable price, are covered below, outside the ranking.

Scores use five weighted criteria, detailed in the methodology. Prices checked in 2026 on the vendors' official pages, before tax. Crowdin bills Enterprise annually; Lokalise shows both annual and monthly rates.

How we compared and scored
We compared these tools from their official pricing and feature pages, then read user reviews, starting with the negative ones. We didn't open vendor accounts: every fact on this page comes from a checked source.
First filter: a public price in US dollars. We couldn't confirm DeepL's US dollar price on its official page, Weblate and Weglot publish their plans in euros only, and Trados Studio's price wasn't readable on its official page. A price we can't read in your currency doesn't go in the ranking. They're covered outside the ranking with what they're good at and where they fall short.
Features weigh 40%, because translation software lives or dies on its translation memory, termbase, file formats and QA. Support weighs 25%: a translator who misses a deadline because of a bug loses a client, and the bad reviews in this category are mostly about support and billing. Value for money weighs 15%, integrations 10% and ease of use 10%.
A tool gets the same scores on every page we publish, so Phrase and memoQ score the same here as on our other language editions. DeepL's score is the one for its DeepL Pro subscription, which also carries DeepL Write, so it matches our paraphrasing tools page.
- Features and depthTranslation memory, termbase, file formats, QA checks, built-in machine translation, project management.40%
- Customer support and assistanceReachability, response times reported in reviews, docs, cancellation and refund terms.25%

- Available integrationsGit, Figma, CMS, Microsoft Office, API, import of other CAT tools' packages.10%
- Ease of useTime to get going, interface clarity, browser-based work.10%
Some vendor links may earn us a commission. That never moves a tool up the list or nudges a score.

Phrase
Phrase puts two products under one login. Phrase TMS is a browser-based CAT tool: segments, translation memory, termbase, QA and machine translation. Phrase Strings handles the string files behind an app or website, with GitHub, GitLab, Bitbucket and Figma integrations. It's the only tool in this ranking that seriously covers two of the three families.
Pricing is public. Freelancer costs $27 a month, billed annually, for one TMS seat and 1,000,000 MTUs a year. An MTU is Phrase's machine translation unit: it counts words sent through the engine, not words you deliver. Software UI/UX, at $525 a month, targets product teams with 15 Strings seats, 1,000,000 managed words in Strings and 500,000 TMS words a year. Team, at $1,245 a month, goes to 20 Strings seats and 2,500,000 TMS words a year.
The 14-day trial unlocks Enterprise features and doesn't charge you when it ends. That's rare in this category, so line up a real project before you start the clock.
The catch: MTUs and managed words take a spreadsheet to forecast. To automate project hand-offs, see Phrase with Zapier. And every listed plan is billed annually, so there's no month-to-month option to trial a single client.
Tip: if a client forces Phrase on you as a freelancer, the $27 plan gives you your own workspace and your own memory. Your segments stay with you when the contract ends.
- CAT and string files in one account
- Freelancer plan at $27/month
- 14-day trial with no auto-charge
- ✓Serves translators and product teams
- ✓Git, Figma, WordPress, Zendesk on Team
- ✓Public pricing
- ✗MTUs and managed words are hard to forecast
- ✗Annual billing only
- ✗Big jump from Freelancer to team plans
The pick when you need two families at once, or a tool that grows with you. Model your MTUs before you sign.
memoQ
memoQ translator pro is a desktop CAT tool. You get translation memory, a termbase, LiveDocs (which turns your past translations into searchable reference) and Muse, predictive typing that suggests how your sentence ends. It also imports packages from the major other CAT tools, which matters when an agency sends you a file prepared elsewhere.
The price is clear: $54 per license per month, or $436 a year. Annual works out to about $36 a month. The official page sells subscriptions only, no perpetual license. The trial lasts 14 days. For agencies, memoQ TMS starts at $3,025 a year with one project manager license and five linguists, hosted on Azure.
User feedback is split. Fans say "memoQ just works", praise the QA and flexible workflows, and find it simpler than Trados for a similar price. Critics mention a busy interface, slowness when working on a client's server and a buggy spellchecker.
The catch: it's desktop software, and advanced support is paid, expensive according to several reviews. It doesn't do Git-wired app localization. That's not its job.
Tip: pay monthly for your first big project, then switch to annual. You save $212 a year versus twelve monthly payments.
- LiveDocs and Muse predictive typing
- Imports other CAT tools' packages
- Monthly plan available
- ✓Very complete CAT workstation
- ✓Clear public pricing
- ✓Widely accepted by agencies
- ✗Busy interface at first
- ✗Reported slowness on servers
- ✗Paid advanced support
The best workstation for a freelancer who wants a full CAT tool without paying for a team platform. Save the 14-day trial for a real client file.
Crowdin
Crowdin is a localization platform used by a lot of software companies and open source projects. It syncs with your repo, shows translators the strings with context, and pushes translations back. Translation memory and glossary are included, and the marketplace lists 700+ apps and integrations.
Pricing starts at $0, then $50 a month for Pro, $150 for Team and $450 for Team+. Paying annually gives you two months free. Paid plans include unlimited translators and proofreaders, which changes the math for community-driven projects. There's also a free open source license and an academic license.
The unit to watch is hosted words: your source words multiplied by the number of target languages. A 20,000-word app in five languages is 100,000 hosted words. Machine translation and AI run on a prepaid balance, on top of the plan.
The catch: a few reviews mention reliability issues on some features and a learning curve for new admins. Older pricing at $59 and $179 still circulates on third-party sites. The official page is what counts. To automate syncs, see Crowdin with Zapier.
Tip: before you pick a plan, remove target languages nobody actually reviews. Each one multiplies your hosted words.
- Free plan and free open source license
- Unlimited translators on paid plans
- 700+ apps and integrations
- ✓Lowest paid entry among platforms
- ✓TM and glossary included
- ✓Strong GitHub and Xcode integrations
- ✗Hosted words multiply by language
- ✗AI and MT billed on top
- ✗Learning curve for admins
The easiest place for a product team to start localizing without a budget fight. Count hosted words, not source words.
Lokalise
Lokalise is the localization platform product teams tend to love on first use. Translation memory, glossary, AI and machine translation, and integrations with Figma, GitHub, GitLab, Jira, Contentful, Webflow and WordPress. Designers can see translated copy in mockups before developers ship it. To connect it to the rest of your tools, see Lokalise with Make or Lokalise with Zapier.
Explorer costs $149 a month billed annually, or $169 month-to-month. Growth is $379 annually or $439 monthly, and Advanced is $1,049 a month annually. The free plan is gone. The 14-day trial doesn't ask for a card.
Reviews are polarized. People praise fast support, the interface, the API and CLI, and the QA checks. The complaints are about contracts: renewal prices that "more than doubled", a 90-day cancellation notice, and every edited word being billed.
The catch: it's the priciest entry point among the platforms ranked here, and the contract terms deserve a lawyer's read. If your team is small, Crowdin's free and $50 plans cover a lot of the same ground.
Tip: ask for the renewal price in writing before you sign the first year, and set a calendar reminder 100 days before renewal to beat the notice window.
- Figma, Jira and CMS integrations
- Trial with no card
- API and CLI praised by developers
- ✓Polished interface
- ✓Fast support in reviews
- ✓Strong design-to-code workflow
- ✗No free plan anymore
- ✗Renewal hikes reported
- ✗90-day cancellation notice
The most polished platform for a funded product team. Negotiate the renewal before you sign, not after.
Smartcat
Smartcat bets on AI translation and browser-based work. Every plan includes unlimited users, so you can bring in reviewers and freelancers without counting seats. Formatting holds up well on documents, and an AEM integration exists for bigger teams. You can also wire it into automations with Smartcat with Make.
Adapt starts at $1,200 a year with 100,000 Smartwords, Smartcat's billing unit. The good part: translation memory is free to use. Matches and repetitions don't burn Smartwords. Higher plans are on quote. On the trust side, Smartcat lists SOC 2 Type II, a DPA, deletion within 30 days on request, and content that isn't used to train public models.
Integrations on Adapt cover Google Drive, Sheets, OneDrive and a Chrome extension. CMS and GitHub connectors start at the Anticipate tier, along with SSO and 2FA.
The catch: reviews from translators paid through the platform mention delayed payouts and withdrawal fees, and support that replies with canned answers. If you're on the buying side, that's less of an issue, but it affects which freelancers want to work there.
Tip: load your existing TMX memory on day one. Since matches are free, a good memory directly cuts your Smartword spend.
- Unlimited users on every plan
- TM matches don't consume Smartwords
- SOC 2 Type II
- ✓Simple browser workflow
- ✓Formatting preserved
- ✓No seat counting
- ✗Git and CMS connectors only on higher tiers
- ✗Translator payout complaints
- ✗Canned support replies
A good fit for content teams that want AI translation with as many reviewers as they need. Check the tier before counting on GitHub sync.
What translation software really costs over a year
Each family bills in its own unit. Here are three sample profiles at official 2026 prices. They're worked examples, not client cases.
A freelance translator
memoQ translator pro annual: $436 a year. Phrase Freelancer: $27 a month billed annually, so $324, with 1,000,000 MTUs of machine translation. OmegaT: $0, but no engine included. Pick one CAT tool, not three. memoQ imports other tools' packages.
A team localizing an app
Crowdin Team at $150 a month is $1,800 a year, or $1,500 with two months free on annual. Lokalise Explorer is $1,788 a year billed annually. Phrase Software UI/UX is $6,300 a year, with 15 seats and unlimited TMS. Pay that only if you also translate documents.
A content team translating at volume
Smartcat Adapt: $1,200 a year for 100,000 Smartwords, with unlimited users. Repetitions and memory matches don't count. A team that reuses a lot of copy gets more out of those 100,000 Smartwords than the number suggests.
- What's the billing unit: characters, words, hosted words, strings, MTUs?
- Does the quota reset monthly, or is it a lifetime total?
- Is translation memory included on your plan?
- Is your content used to train a model?
- Does the plan auto-renew after the trial, and what's the notice period?
- Can you export your memory as TMX and your glossary if you leave?
Other tools worth knowing
These come up in every search. They're not ranked here because we couldn't read a US dollar price on their official page. They're still strong picks in their family.
DeepL Pro: machine translation for everyday documents
Machine translationDeepL Pro is the engine reviews praise most for output quality. It keeps document formatting and plugs into Word, Microsoft 365, Outlook and Google Workspace, and into automations with DeepL with Make. Pro content isn't used for training and is deleted after processing, with ISO 27001 and SOC 2 Type II. Translation memory only comes with the Business plan. The most common complaint: a full year charged after the trial, with no refund.
- Free plan
- 50,000 characters a month
- Trial
- 30 days, once
Trados Studio: the tool agencies still ask for
CATTrados Studio is still the CAT tool many agencies require. Perpetual licenses and subscriptions coexist. We couldn't read its price on the official page, so ask for a written quote and have the upgrade cost and Freelance license terms spelled out.
- License
- Perpetual or subscription
- Price
- Written quote
Weblate: open source localization, EU hosting
LocalizationWeblate is open source localization software you can self-host for free, or use hosted with data and backups stored in the EU. Hosted plans bill by strings, not seats, and are priced in euros only. A free Libre plan covers public open source projects.
- Self-hosted
- Free, open source
- Data
- Stored in the EU
Weglot: translate a website without a developer
WebsiteWeglot detects your site's text, translates it and publishes translated pages on WordPress, Shopify, Webflow and more. A free plan covers 2,000 words and one language. The word limit counts unique translated words and doesn't reset monthly. Pricing is listed in euros.
- Free plan
- 2,000 words, 1 language
- Trial
- 14 days
OmegaT: free, open source CAT
FreeOmegaT is GPL 3 open source CAT software for Windows, macOS and Linux, with TMX memory and XLIFF support. It's the best way for a new translator to learn segment-based work without paying. The interface is basic, and some formats need tweaking.
- Price
- $0, open source
- Formats
- TMX, XLIFF
Wordfast: a CAT tool some agencies ask for
CATWordfast is a CAT tool an agency may ask you to use. Before buying a second tool, check whether memoQ, which imports other CAT tools' packages, covers that client, or whether the agency accepts XLIFF. We didn't read a current price on its official page, so it stays unranked.

What makes the bill explode
Mistakes that show up again and again in user reviews, and how to dodge them before you pay.
Letting a trial roll into a full year
BillingDeepL's top complaint is a year charged at the end of the trial, no refund. Lokalise customers cite a 90-day cancellation notice and renewals that doubled. Put the trial end date and the notice deadline in your calendar the day you sign up.
- Habit
- Turn off auto-renew on day one
Comparing prices in different units
PricingCrowdin counts hosted words times languages. Phrase counts MTUs through the engine. Smartcat counts Smartwords but not memory matches. Convert your real volume into each vendor's unit before comparing two price tags.
- Rule
- Price per delivered word, not per plan
Leaving your memory with the vendor
DataYour translation memory is your asset. Switch tools without exporting it and you start from zero. Export your TM as TMX and your glossary as TBX or CSV every quarter, even if you're not planning to leave.
- Formats
- TMX for memory, TBX or CSV for glossaries
Pay less and translate better, whatever the tool
Simple moves, pulled from official pages and user feedback.
Start with the glossary, not the translation
QualityTwenty well-defined terms (product names, legal terms, formal or informal tone) save hundreds of fixes later. Load the glossary before the first segment, in whatever tool you pick.
- Starting point
- 20 key terms
Only localize languages someone reviews
SavingsOn Crowdin and Weblate, every target language multiplies your volume. A language with no reviewer ships machine output to customers. Launch with the languages you can check, then add more.
- Effect
- Each language multiplies hosted words
Try monthly, then pay annually
SavingsmemoQ sells monthly and annually. Try one month on a real job, then switch: $436 a year instead of $648 for twelve months. Crowdin's annual billing gives two months free.
- memoQ savings
- $212 a year

Your questions about translation software
What software do professional translators use?
Mostly CAT tools, such as Trados Studio, memoQ or Phrase, which often show up in agency requirements. Clients sometimes pick the tool for you. memoQ imports packages from other CAT tools, so you don't have to buy all of them.
What's the difference between translation and localization?
Translation moves text from one language to another. Localization adapts a whole product to a market: date formats, currencies, button lengths, images. A localization platform manages string files and context, not just sentences.
Is there a free CAT tool?
Yes. OmegaT is free and open source on Windows, macOS and Linux, with TMX memory. For product teams, Crowdin has a free plan and a free open source license, and Weblate is free to self-host.
Is DeepL safe for confidential documents?
On Pro plans, DeepL says your text isn't used for training and is deleted after processing, and it holds ISO 27001 and SOC 2 Type II. The free version doesn't come with those commitments, so keep contracts off it.
What is translation memory?
It's a database that stores every source sentence with its approved translation. When the same or a similar sentence comes back, the tool suggests it. On manuals and app updates, repeated text adds up fast, and Smartcat doesn't even bill those matches.
Can machine translation replace a human translator?
For understanding a document or an internal email, often yes. For a contract, a sales page or marketing copy, no: it needs human review. The workable setup is the engine for the first draft and a translator for what gets published.
How do I translate a WordPress site without a developer?
Use a website translation plugin such as Weglot. It detects text, translates it and publishes translated pages. Its free plan covers 2,000 words, enough to try on your homepage. Count your site's words before choosing a paid plan.
Which file formats let me switch tools without losing work?
Export your memory as TMX, your glossary as TBX or CSV, and your files as XLIFF. memoQ, Phrase, OmegaT and most platforms read all three. Run the export before your subscription ends.
