🚀 Mockoon v9.5.0 is out! Callbacks now support relative URLs, so you can call endpoints inside the same mock without hardcoding full URLs. Example: /test-callback resolves to localhost:3000/test-callback CLI/Docker users can override the base with --public-base-url ➡️ mockoon.com/releases/9.5...

I had a great chat about OSS funding with my friend @255kb.1kb.software Monnet from @mockoon.com core team at @fosdem.org and happy to announce I am a github sponsor for the project.

🎉 Mockoon just reached 8,000 GitHub stars. Huge thanks to everyone who starred the repo, reported issues, sent PRs, shared feedback, or supported the project in any way. Your involvement is what keeps Mockoon moving forward. On to the next chapter 🚀

🎉 Happy new year! As we wrap up 2025 and head into Mockoon's ninth year, we wanted to pause and say thank you to everyone who uses Mockoon, gives feedback, reports issues, contributes, or supports the project. That's what makes it sustainable. Looking forward to what we'll build together in 2026 🚀

We'll be participating in a session dedicated to funding and sustaining open-source projects at FOSDEM, alongside DuckDB and WeasyPrint. Proud to represent Mockoon and contribute to the conversation around building sustainable, independent open-source software. ➡️ www.linkedin.com/events/74149...

We just opened a new EU region located in EU West (Belgium). Teams operating in Europe can now deploy their cloud mocks closer to their users for better performance.

New in Mockoon v9.4.0: You can now view local and cloud logs together in the desktop app, with filters to quickly focus on what you need. Cloud logs also finally persist across sessions. Close the desktop app or refresh the web app and your logs will reload automatically instead of disappearing.

OpenAPI in Mockoon just got a proper upgrade. The web app now supports import from file/URL/clipboard with a preview, plus export to JSON or YAML. Desktop and web now share the same engine too.

Mockoon v9.4.0 is live: better OpenAPI import/export, persistent cloud logs, new helpers, smoother local→cloud flow. Check it out! mockoon.com/releases/9.4...
