Tolgee
Open-source localization platform with in-context editing and a context-aware AI Translator for app copy.
Pick Tolgee when developer time is the real bottleneck, not translation quality. In-context editing plus a context-aware AI Translator, on a €0 tier that still includes every SDK, the Figma plugin, the MCP server, 30,000 hosted words and 3 seats, is a genuinely usable starting point. Keep the ceiling in view: review chains stop at tasks and branching, there is no vetted human translator marketplace, and the Apps plugin platform only emerged from its first internal hackathon in July 2026.

Skip Tolgee if you need a managed marketplace of vetted human translators with formal review chains, or if you are not prepared to monitor hosted-word usage, since each translated language is counted as separate words against your plan.
Hosted words are counted per language, so a key with 2 base words and a 1-word German translation consumes 3 hosted words — multi-language products hit the 30,000-word Free cap faster than the number suggests.
Tolgee's self-serve ladder — Free at €0, Translate at €58/mo billed annually, Optimise at €133/mo billed annually, Manage at €373/mo billed annually — fits solo developers through mid-size product teams, with unlimited seats from Translate upward. Teams that need SSO, an account manager, or on-premises licensing move to quoted Enterprise and On-Premises tiers. Compared with per-seat localization platforms, the metered hosted-word model tends to be cheaper until you ship many languages.

About Tolgee
Tolgee is an open-source localization platform built around editing your app's copy where it actually lives: inside the running application. Drop in a JavaScript SDK, or the iOS and Android SDKs, and a project lead, a client, or a community volunteer can change a label on screen while the app is live, no spreadsheet handoff and no developer ticket. Dev tools pull the UI context around each string and capture one-click screenshots, and that context feeds the AI Translator, which mixes in your project description, brand voice, and glossaries so the output reads like your product instead of a literal gloss. The surrounding workflow is the familiar localization stack: translation memory (shared across all your projects as of August 2026), machine translation through Google Translate, AWS, and DeepL or your own API keys, tasks with reports, branching, granular permissions, activity logs, and webhooks. A CLI and REST API cover import/export and CI/CD wiring, a Figma plugin handles the design-to-localization step, and an MCP server lets AI coding tools like Claude Code create, translate, and tag keys. Content Delivery pushes approved translations to AWS S3 or Azure blob storage, so a wording fix reaches users without an app release. Pricing bills on hosted words rather than seats, and seats are unlimited on the current paid plans. The Free tier is €0 with 30,000 hosted words and 3 seats; Translate, Optimise, and Manage run €58, €133, and €373 per month billed annually, each with 400,000 MT credits. Enterprise and On-Premises are quoted, and self-hosting lets teams run Tolgee on their own infrastructure under ISO 27001 and GDPR constraints. The pitch is aimed at developer-led SaaS teams and agencies where engineering time, not linguistic nuance, is the bottleneck. Compared with seat-priced TMS incumbents and managed translator marketplaces, Tolgee trades a vetted linguist network for in-context speed and open-source deployability.
Behind the Verdict
The interesting thing about Tolgee isn't the feature checklist, it's the direction of the workflow. Most localization tools assume strings are frozen assets that get exported, translated elsewhere, and imported back. Tolgee assumes the string is still alive in a running app, and lets a non-developer edit it there. That choice pays off in a specific situation: a client or product owner wants to fix a headline, a typo, or a tone problem, and the alternative is a Jira ticket and a release cycle. In-context editing turns that into a two-minute change. The dev tools that extract UI context are what make the AI Translator more useful than a raw MT API call, since a button label surrounded by its screen context gets translated differently than the same words in a spreadsheet cell. We'd reach for this when the team is React, Vue, Angular, Svelte, Next.js, or Flutter, and when developer hours are scarce. The Free tier is unusually complete for evaluation: all the SDKs, the Figma plugin, the MCP server, 30,000 hosted words, 3 seats. For agencies handing clients an editable preview, that alone often closes the deal. Where it bites: hosted words are counted per language and per base text, so a wide language rollout grows the bill in a way seat-based pricing doesn't. If you're on a legacy plan, unlimited seats means migrating plans. The Apps plugin platform is young, first stress-tested in a July 2026 internal hackathon, so don't expect a deep marketplace of third-party extensions. If your must-have is a managed, vetted translator marketplace with linguistic QA sign-off, Tolgee isn't competing there and shouldn't pretend to. I'd look at a vendor with a translator network instead. Same answer for a project with a dozen strings, since the SDK setup costs more than the problem.

Real-world workflow fit
Concrete scenarios for the personas Tolgee actually fits — and what changes day-one when you adopt it.
You add the Tolgee JavaScript SDK to your React app, let the dev tools capture context and screenshots for each string, then run the AI Translator with your project description and a brand glossary loaded.
Outcome: Strings ship translated in the same sprint instead of waiting on a spreadsheet hand-off, and you keep the CLI in CI to push and pull keys on every merge.
You hand the client an in-context editing link inside the running staging build so they change their own marketing copy and correct terminology in place, with tasks tracking which strings still need review.
Outcome: Copy changes stop routing through developer tickets, and the client sees edits live rather than reviewing a column in Excel.
You stay on the €0 Free plan with 3 seats, use tags and tasks to direct dozens of community contributors, and run a self-hosted instance so translations live on your own infrastructure.
Outcome: Community languages grow without a localization budget, and Content Delivery pushes approved strings to your storage without cutting a release.
Use Cases
- Let a client or product manager edit live app copy in context without filing a developer ticket.
- Auto-translate strings with UI context, brand voice, and glossaries so tone stays consistent across locales.
- Organize multi-language releases with tasks, branching, and labels instead of spreadsheets.
- Push translation fixes to users through Content Delivery without shipping a new app version.
- Extract and sync translations from Figma designs before development starts.
- Wire import/export into CI/CD with the CLI, REST API, or webhooks.
- Manage open-source community translations across dozens of languages.
- Create, translate, and tag keys from Claude Code through the Tolgee MCP server.
Limitations
- AI translation is machine translation and still benefits from human review, especially for brand-sensitive copy.
- Professional translation ordering and community translators are marked 'coming soon' on the features page, so there is no in-platform marketplace of vetted linguists yet.
- Hosted MT credits are the pricing metric — the Free tier includes 30,000 words and 3 seats, while paid plans include 400,000 MT credits and unlimited seats; enterprise needs (SSO, premium support, dedicated Slack) require the custom-quoted Enterprise plan.
- The upcoming Apps plugin platform is early-stage — Tolgee ran its first internal hackathon for it 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 self-serve ladder — Free at €0, Translate at €58/mo billed annually, Optimise at €133/mo billed annually, Manage at €373/mo billed annually — fits solo developers through mid-size product teams, with unlimited seats from Translate upward. Teams that need SSO, an account manager, or on-premises licensing move to quoted Enterprise and On-Premises tiers. Compared with per-seat localization platforms, the metered hosted-word model tends to be cheaper until you ship many languages.
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.
One developer can add the JavaScript SDK and see in-context editing in a running app in under an hour for a small project. Android and iOS SDK setup takes longer depending on your build pipeline. Non-technical teammates need no setup at all — you invite them and they edit strings directly in the app preview. Teams wiring the CLI into CI/CD should budget another half day.
Switching to or from Tolgee
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From react-i18next: import your existing JSON locale files through the Tolgee UI or CLI, then swap the i18n provider for the Tolgee SDK to gain in-context editing.
- →From spreadsheet translation workflow: push your column-based sheets in through CSV import and let the dev tools add UI context going forward.
- →From a per-seat localization platform: export your translation memory, import it into Tolgee, and consolidate seats onto a plan with unlimited seats.
- →From self-managed JSON files in the repo: run the Tolgee CLI to extract keys and sync them, keeping files generated rather than hand-edited.
- →From LinguiJS: migrate your message catalogue via the CLI import path and keep your existing key naming as Tolgee keys.
- ↗To a human-translator marketplace vendor: export your base texts and translation memory, since Tolgee does not offer an in-platform linguist marketplace.
- ↗To react-i18next: pull translations with the CLI into JSON locale files and drop the Tolgee runtime if you no longer need in-context editing.
- ↗To a spreadsheet workflow: use the UI export to produce per-language files your reviewers can open without platform access.
- ↗To a self-hosted setup: keep your project and switch from cloud to the self-hosted distribution to move data onto your own infrastructure.
