Some maintenance is easy to postpone, and a Kubernetes upgrade is a common example — until the running version goes out of support. By the time we started, our production Azure AKS cluster could only move in a single jump from Kubernetes 1.27 to 1.33, six minor versions at once. This post covers why the delay made the work larger and riskier, the problems we hit during the upgrade, and what running a supported Kubernetes version means for the people who use Tolgee.

The Tolgee MCP server lets the AI agent in your editor manage localization directly — creating, translating, and tagging keys from chat. A hands-on walkthrough: connecting Claude Code to Tolgee and running a real React app through two everyday workflows

In June we ran our first internal hackathon to stress test Tolgee Apps, our upcoming plugin platform. Five people, three days, five very different apps. Here’s how it went and what we learned.

Picking a React i18n library is a decision you live with for years, and migrating later hurts. This is a practical comparison of the four most popular choices in 2026: react-i18next, react-intl, Tolgee, and LinguiJS. Less hello-world setup, more of what's easy to miss at the start and what bites you once you scale.

We needed a plugin system for Tolgee, but we didn't want to host plugin code, manage plugin storage, or share a JavaScript context with untrusted extensions. Here's how we designed it, what tradeoffs we accepted, and why iframes turned out to be the right call.

When a localization project grows past a few hundred keys, structure starts to matter. This guide walks through every layer of key organization in Tolgee. When to use projects vs. namespaces, how tags handle everything in between, why semantic key naming saves you from translation errors down the road, and the most common mistakes that only hurt months later.

How a localization workflow of Splital, an expense-splitting mobile app, changed after Tolgee MCP was introduced.

AI makes it easy to produce more code, faster. But it also makes it easy to produce more mess. After months of working with AI coding tools, I'm more convinced than ever that DRY and SOLID principles are not relics of the past. They're the foundation that makes AI-assisted development actually work.

Clients always want to tweak their texts. With Tolgee's in-context editing, they can do it themselves, right in the running app. No tickets, no developer in the middle.

Climate Fresk scaled climate education to over 2 million participants worldwide. Powered by a community-driven localization workflow. Learn how they manage translations in 40+ languages and automate multilingual content generation using Tolgee.

Five years ago we registered Tolgee as a legal entity. We were younger, probably a bit naive, and very determined to build something that actually mattered for developers. A lot has happened since then. This post is not about all five years. It is about the last one, which turned out to be the most eventful we have had. We grew 2.9x in ARR. The team changed. We shipped a lot. Here is what happened.

Have you ever wondered why Tolgee is named the way it is, or why a mouse appears in its logo? In this article, we share the journey and creative process behind choosing our company name and mascot, from playful wordplay to discovering inspiration in unexpected places.

How native localization helped Curipod stabilize their React app and scale globally without slowing devs down.

In 2025, the development of Tolgee was focused on improving the platform experience, mobile SDKs, and the Figma plugin.

Tolgee and, in particular, its React SDK @tolgee/react just hit the milestone of 50,000 weekly downloads on npm JS.
