TL;DR: The main Lokalise and Crowdin alternatives are Phrase (enterprise suite), Tolgee (open source, in-context editing, free tier), Locize (i18next, from $7/mo), Weblate (open source, Git-native) and, for code that isn't internationalized yet, tools that wrap hardcoded strings such as i18next-cli. Crowdin, Tolgee and Locize have free plans; Lokalise and Phrase offer only trials.
Lokalise and Crowdin are built for localization teams: translators, reviewers, vendors and workflows. If you are a developer who mostly wants your app to speak more languages, you may be paying for a translator workspace you never open, or discover that the tool assumes your strings already live in translation files. This guide compares six alternatives on what developers actually care about, with prices checked on October 16, 2026.
First, Know Which Problem You Have
Localization tools solve one of two different problems, and most comparisons blur them:
-
Managing translations. Your app already uses
t("checkout.title")and has locale files. You need a place where translators and machine translation fill in other languages, and a sync that brings them back to your repo. This is what a translation management system (TMS) does: Lokalise, Crowdin, Phrase, Tolgee, Locize and Weblate. -
Internationalizing the code. Your app still has
<h1>Welcome back</h1>hardcoded in hundreds of components. Before any TMS can help, someone has to find those strings, replace them with translation calls, set up the i18n library and create the locale files.
Every TMS below starts at step two. Their own documentation describes importing translation files or keys that already exist. If you are at step one, that is the work to solve first.
The two are not either-or. A common path is to internationalize the code first, then add a TMS only if and when you bring in human translators. The locale files are plain JSON or gettext either way, so any of the tools below can take over from there.
The Alternatives at a Glance
| Tool | Free plan | Cheapest paid plan | Open source | Opens PRs in your repo |
|---|---|---|---|---|
| Lokalise | No (14-day trial) | Explorer: $169/mo, or $149/mo billed yearly | No | Yes |
| Crowdin | Yes: 60K hosted words, 1 private project | Pro: $59/mo, or from $50/mo billed yearly | No | Yes |
| Phrase | No (14-day trial) | $525/mo billed yearly for a developer team plan | No | Yes |
| Tolgee | Yes: 30,000 words, 3 seats | Translate: €69/mo ($79), or €58/mo billed yearly | Yes, self-hostable | Through the CLI in CI |
| Locize | Yes: 2,000 words, 2 languages | Starter: $7/mo | No | Through GitHub Actions |
| Weblate | Self-hosting free; hosted free for public projects | €47/mo (10,000 hosted strings) | Yes (GPLv3+) | Yes |
Prices are the vendors' public list prices on October 16, 2026, and they change. The units also differ: hosted words, hosted strings, seats or characters, so compare the limit that matters for your app, not just the dollar figure.
Crowdin: The Generous Free Plan
Crowdin's free plan is the most usable in this list: 60,000 hosted words, one private project, unlimited public projects and unlimited translators, with Crowdin AI and machine translation included. Hosted words are words multiplied by target languages, so 60,000 is about 6,000 source words in ten languages. The catch, from its pricing page: users on the free plan donate translations to Crowdin's translation memory. Open-source projects can apply for a free license if they meet conditions such as an OSI license, public code and an active community.
The GitHub integration syncs your source and translation files and opens pull requests from an l10n_ branch. Best for: projects that bring in many outside or volunteer translators. (pricing, GitHub integration)
Lokalise: Strong Workflows, No Free Plan
Lokalise has no free plan, only a 14-day trial. The entry Explorer plan is $169 a month ($149 billed yearly) for 5 projects and 10 languages, with unlimited translator and reviewer seats, 5 advanced seats, and a quota of machine-translated words from DeepL and Google Translate. Its GitHub integration pulls your language files and opens pull requests. The strengths are on the team side: translation memory, glossaries, tasks, in-context editors and over-the-air SDKs that update mobile apps without a release. (pricing, GitHub integration)
Phrase: Enterprise Depth
Phrase Strings is part of a suite that also translates documents. Its cheapest plan that includes Strings seats for a team is $525 a month billed yearly. It syncs with GitHub, GitLab and Bitbucket and exports translations as pull requests. If you need vendor management, quality review and one platform for software and documents, it is a serious option; for a small team it is a lot of tool. (pricing)
Tolgee: Open Source With In-Context Editing
Tolgee is open source (Apache-2.0, with enterprise parts licensed separately) and can be self-hosted for free with up to 10 seats. The cloud has a free plan of 30,000 words and 3 seats. Its standout feature is in-context editing: hold Alt, click a string in your running app and translate it on the spot. Its CLI extracts keys already used through the Tolgee SDK for React, Vue and Svelte, so you still write the translation calls yourself. (pricing, CLI extraction)
Locize: Cheapest Paid Plan, Built for i18next
Locize comes from the creators of i18next and is the cheapest paid option here at $7 a month for 15,000 words and 5 languages. Its distinguishing feature is delivery through a CDN, so translation updates can reach users without a redeploy. If you already use i18next it fits naturally. The same team publishes i18next-cli, covered below. (pricing)
Weblate: Open Source and Git-Native
Weblate is a web TMS built on version control, licensed GPLv3+ and free to self-host. Hosted plans start at €47 a month for 10,000 hosted strings, where hosted strings are source strings times the number of languages plus one. Public open-source projects can use the free Libre plan. It opens merge requests with translation changes and supports many engines, from DeepL to self-hosted Ollama. (hosting, version control)
If Your Strings Are Still Hardcoded
None of the platforms above will turn <h1>Welcome back</h1> into a translation call across your codebase. These tools do part or all of that job:
-
i18next-cli
instrument(free, MIT). It scans source code for hardcoded user-facing strings and wraps them in i18next calls. Its README says it is heuristic and will not catch every case, and its docs cover React and JavaScript/TypeScript. A good free start for React apps. (GitHub) - Editor extensions. Lokalise's i18n Ally has experimental "extract hard-coded strings" commands that work one file at a time, and Crowdin's VS Code extension extracts a selected string to a key you type. Useful for touch-ups, slow for a whole app.
List prices are hard to compare because each tool counts differently. Take a typical small SaaS app: 500 UI strings averaging 5 words and 30 characters, so about 2,500 source words and 15,000 source characters, translated into 5 languages. Using each vendor's own counting rules:
| Tool | How it counts | This app | Plan that fits |
|---|---|---|---|
| Crowdin | Hosted words × target languages | 12,500 hosted words | Free (60K) |
| Tolgee | Hosted words | 12,500 | Free (30,000) |
| Locize | Words and languages | 2,500 words, 5 languages | Starter, $7/mo |
| Weblate | Source strings × (languages + 1) | 3,000 hosted strings | €47/mo hosted, or free self-hosted |
| Lokalise | Seats, projects, languages | 1 project, 5 languages | Explorer, $149–169/mo |
| Phrase | Seats and managed words | within limits | $525/mo billed yearly |
One thing the table does not show: these prices assume your strings are already in translation files. None of these tools does the work of getting them there; for that, see the section on hardcoded strings above.
So for this app, Crowdin or Tolgee is cheapest for managing translations, Locize is cheapest among paid plans, and Lokalise or Phrase only make sense if you need their team workflows.
How to Choose
- Strings still hardcoded: start with code instrumentation (i18next-cli gives a free partial pass in React), then decide whether you need a TMS at all.
- Volunteer or outside translators: Crowdin or Weblate.
- Open source and self-hosted: Tolgee or Weblate.
- Already on i18next, small budget: Locize.
- A localization team with reviewers and vendors: Lokalise or Phrase.
Whichever you choose, the locale files are plain JSON or gettext in your repo, so you are not locked in. See JSON translation files explained for the format, translation memory explained for what a TMS adds, and the SaaS localization guide for the full process.
Frequently Asked Questions
Is there a free alternative to Lokalise?
Yes. Crowdin has a free plan with 60,000 hosted words and one private project, Tolgee's cloud is free up to 30,000 words and 3 seats, Locize is free for 2,000 words, and Weblate and Tolgee can be self-hosted for free. Lokalise itself only offers a 14-day trial.
What is the cheapest Crowdin alternative?
Among paid plans, Locize starts at $7 a month. Self-hosting Tolgee or Weblate costs only your server, if you are comfortable running it.
Do Lokalise or Crowdin find hardcoded strings in my code?
Not as a platform feature. Both manage translation files and keys that already exist. Lokalise's i18n Ally extension can extract strings experimentally, one file at a time, and Crowdin's VS Code extension extracts a selected string. To wrap strings across a whole repo, use a code instrumentation tool such as i18next-cli.
Which localization tools are open source?
Tolgee (Apache-2.0 for its core) and Weblate (GPLv3+) are open source and self-hostable. Lokalise, Crowdin, Phrase and Locize are proprietary services.
