Tolgee
Open-source localization with in-context editing and AI translation
A practical pick for developer-led teams; in-context editing is the standout, and AI translation with brand context reduces manual work. The free tier is generous. But if you need vetted human translation or complex review chains, look at Lokalise or Crowdin.

Skip Tolgee if you need vetted human translation services right away, or if your project has only a handful of strings that don't need collaboration.
Going past 500 keys on the free plan requires upgrading to Team at €49/mo, which is a jump if you're just exploring.
Tolgee's free tier (500 keys, 3 seats) is generous for small projects, and the Team plan at €49/mo is competitive with Crowdin's $45/mo Starter. However, to unlock granular permissions, branching, and a larger MT credit pool, you need to jump to Business at €179/mo, which is pricier than Lokalise's $75/mo Pro. For cost-conscious startups, self-hosting is an option but requires infrastructure investment.

About Tolgee
Tolgee is an open-source localization platform that lets you edit app text directly in your running application, eliminating the developer bottleneck. Its in-context editing SDKs for React, Vue, Angular, Svelte, and Next.js allow non-technical team members to modify translations with a live preview. The AI translator uses surrounding UI context, brand voice, and glossaries to produce translations that fit your product. Tolgee includes a translation memory, machine translation, tasks, branching, granular permissions, and an activity log for team coordination. Its content delivery network (CDN) pushes translation updates to users without a new app release. The platform integrates with Slack, Figma, and offers an MCP server for AI-assisted workflows, plus a CLI, REST API, and a Figma plugin. Self-hosting is available, and Tolgee holds ISO 27001 and GDPR certifications. Pricing is freemium: a free tier (500 keys, 3 seats, 10,000 MT credits) and paid plans (Team, Business, Advanced, Enterprise) scaling to 20,000+ keys, with pay-as-you-go options for extra keys, seats, and MT credits. Recent blog posts (mid-2026) highlight shared translation memory across projects, a plugin system built on iframes, and a guide to organizing translation keys. Compared to Crowdin or Lokalise, Tolgee focuses on developer ergonomics and open-source flexibility, though professional human translation services are still 'coming soon.'
Behind the Verdict
Tolgee hits a sweet spot for teams that live in code. The in-context editing is genuinely different — your QA or product person can fix a typo in French without filing a ticket. That alone removes a ton of back-and-forth. When to pick it: you're a SaaS with a React or Vue frontend, you want to give clients or non-devs edit access, and you like the idea of open source with self-hosting options. The AI translator uses the app's UI context to improve accuracy, which is a real step up from generic machine translation. When to pass: if your localization pipeline depends on professional human translation services, Tolgee still says 'coming soon'. That's a gap. Also, if you need heavy workflow automation like complex review chains or advanced branching, the task system is solid but not enterprise-grade. Closest alternative is Lokalise or Crowdin. They're more mature on human translation services and workflow depth, but they cost more and lock you into their cloud. Tolgee's open-source core and self-hosting are a legit draw for privacy-focused teams. One caveat: the free tier is 500 keys and 3 seats — fine for a small app or a trial, but you'll outgrow it quickly. Pay-as-you-go pricing for extra keys and seats is reasonable, though. In practice, we'd reach for Tolgee when the bottleneck is developer time, not translator quality. If you're burning sprints on string changes, this pays for itself fast.

Real-world workflow fit
Concrete scenarios for the personas Tolgee actually fits — and what changes day-one when you adopt it.
You're building a React app and want to add Spanish and German. You integrate the Tolgee SDK, add a few keys, and the AI translator auto-translates them using your brand context. You review the translations in the live in-context editor and publish them via CDN—no developer help needed.
Outcome: You launch your app in two new languages within a day, without writing a single translation file.
Your client wants to update translations for their marketing site. You've set up Tolgee with the Figma plugin and given your client access. They edit text directly in the app, preview changes, and you approve via tasks.
Outcome: The client handles their own translations, saving hours of back-and-forth, and you retain control with granular permissions.
You manage a project with 45+ languages. You set up Tolgee for volunteer translators, who use the in-context editor to add translations. The shared translation memory (from the July 2026 update) ensures consistency across languages.
Outcome: Your community contributes translations easily, and translation consistency improves across all languages.
Use Cases
- Integrate Tolgee SDK into your React app and enable in-context editing for non-technical team members.
- Use AI auto-translation with brand context to maintain consistent tone across all languages.
- Set up tasks and branching to manage translation workflows for multiple language releases.
- Deploy translated content via Tolgee's CDN to update your app instantly without rebuilding.
- Leverage the Figma plugin to extract and manage translations directly from your design files.
- Export translations via CLI or REST API to integrate with your existing CI/CD pipeline.
- Use Tolgee MCP integration to streamline localization in AI-assisted development workflows (see Splital case study).
- Manage volunteer translations for open-source projects with 45+ languages (see Climate Fresk case study).
Limitations
- AI auto-translation uses machine translation and may require manual review for accuracy.
- The free plan has no key or seat limits mentioned.
- Professional translation ordering and community translators are listed as 'coming soon' and not yet available.
- Advanced features like branching, granular permissions, and AI playground are only available on higher-tier paid plans.
- The plugin system is still in early development (first hackathon in July 2026).

Where the pricing makes sense
The company stage and team size where Tolgee's pricing actually pencils out — and where peers do it cheaper.
Tolgee's free tier (500 keys, 3 seats) is generous for small projects, and the Team plan at €49/mo is competitive with Crowdin's $45/mo Starter. However, to unlock granular permissions, branching, and a larger MT credit pool, you need to jump to Business at €179/mo, which is pricier than Lokalise's $75/mo Pro. For cost-conscious startups, self-hosting is an option but requires infrastructure investment.
Setup time & first value
How long it actually takes to get something useful out of Tolgee — broken out by persona, not the marketing-page minute.
A developer can integrate the Tolgee SDK in a React app in under 30 minutes (following the JS SDK docs). Non-technical users can start editing translations immediately after setup. Setting up the Figma plugin takes about 15 minutes. The MCP server integration with Claude Code is a bit more involved, but the July 2026 walkthrough shows it can be done in under an hour.
Switching to or from Tolgee

- →From Crowdin: Export your translation files (e.g., JSON, .po) and import them via Tolgee's REST API or UI. You can also use the CLI to automate the transfer. Your translation memory can be recreated by importing
- ↗To Lokalise: Export your translations via Tolgee's REST API or CLI, and import them using Lokalise's import tools. Note that in-context editing metadata may not transfer.
- ↗To Crowdin: Similar to above—export files and import into Crowdin. You may need to manually recreate tasks and branching structures.
