The two most popular translation management systems compared on pricing, features, developer experience, and what both of them are missing.
Crowdin and Lokalise are the two most commonly compared translation management systems. Both are mature platforms used by thousands of teams. But they're built for different workflows, and the pricing structures tell you a lot about who each tool is designed for.
Here's an honest comparison — including what both platforms are missing and when you might want a different approach entirely.

Crowdin has been around since 2009 and it shows — 700+ apps and integrations, SDKs for major platforms, and a translator marketplace where you can find and hire professionals directly. If you need to connect your TMS to less common tools, there's a good chance Crowdin has an integration.
Crowdin's translator marketplace is one of its biggest strengths. You can find translators, get quotes, assign work, and manage the vendor relationship inside the platform. Lokalise has vendor features too, so compare both if agencies are central to your workflow.
Crowdin's paid plans start at $59/month. Translators and proofreaders are unlimited on paid plans, and the price scales with hosted words and manager seats. At the entry level, that's well below Lokalise's $149/month Explorer plan.
Both platforms offer over-the-air delivery, so you can update mobile translations without an app-store release. Check SDK support for your stack (iOS, Android, React Native, Flutter) on each.
Lokalise's screenshot feature is well built. You can upload screenshots of your app, link them to translation keys, and translators see where each string appears in the UI. That context helps — a translator who can see that "Save" is on a small button will write a shorter translation than one who sees "Save" in a spreadsheet. (Crowdin supports screenshots too.)
Lokalise's in-context editors (web and mobile) let translators work on strings in the context of your app. Crowdin has in-context translation too; try both with your own app before deciding.
Lokalise supports translation branching that mirrors your git branches. When you create a feature branch, you can create a corresponding translation branch, work on new strings in isolation, and merge when ready. This prevents translation conflicts in teams with multiple concurrent features. (Crowdin also supports branches.)
Lokalise puts a lot of work into its editor UI, and plenty of teams prefer how it feels. For teams that spend significant time in the TMS dashboard, that matters — so use both trials and see which your translators like.
Neither Crowdin nor Lokalise scans your source code for hardcoded strings. They manage strings that already live in translation files. The tedious, error-prone work of auditing your source code to find hardcoded strings — and then wrapping each one in a translation function — is on you.
For a Next.js app with 200 components, this extraction step can take days. And every new feature introduces new hardcoded strings that need to be found and extracted before either platform can manage them.
Both platforms have CLIs and APIs, but day-to-day translation work happens in their web dashboards. That means syncing files and managing translation state in a separate system from your code. For developer-led teams who'd rather start from the terminal, this adds friction.
Crowdin's free tier is 1 private project. Lokalise has no free plan, just a 14-day trial. For a startup with 2-3 projects and 3 developers, you're looking at $59-149+/month before you've translated a single string — and usage limits (hosted words on Crowdin, processed words on Lokalise) can push you up a tier.
If the comparison above made you think "neither of these is quite right for my team," you might want a different category of tool entirely. Polyglot is a CLI tool that starts with detection — it scans your source code with tree-sitter AST parsing, reports hardcoded-string candidates, wraps them from a plan you review, translates with LLMs, and previews locally. Generated translations are reviewed in Polyglot's dashboard before they're approved.
| Crowdin | Lokalise | Polyglot | |
|---|---|---|---|
| Hardcoded-string detection | Not built in | Not built in | Yes (AST) |
| Primary interface | Dashboard (plus CLI/API) | Dashboard (plus CLI/API) | CLI, with dashboard review |
| AI translation | Crowdin AI, MT engines | Included per plan | Built-in |
| Previewing translations | In-context tool | In-context editors | Local (polyglot preview) |
| Free tier | 1 private project | None (14-day trial) | Local scan/wrap/preview; 500 lifetime strings |
| Starting price | $59/mo | $149/mo | $49/mo ($39 annual) |
| Translation memory | Yes | Yes | Yes |
Polyglot isn't a TMS — it doesn't replace Crowdin or Lokalise if you need vendor management, professional translator workflows, or over-the-air delivery. But for developer-led teams who want to find hardcoded strings, translate them, and preview the results starting from the terminal, it's a different approach.
