🚀 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

Localization is not just about translation but also understand how a brand will be perceived.
I remember a long time ago talking with a (Korean, iirc) music streaming platform called kkbox. They wanted to set foot in France without changing their name 😅

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.

Mockoon - 2025 retrospective and Mockoon 8th birthday Let's take a look back at 2025 and celebrate 8 years of Mockoon!

🎉 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 🚀

It happened to me once, and now I always pay for 10 years.

What do you use to detect disposable email addresses?

Just pushed a nicer OpenAPI workflow in Mockoon's web app. Import from URL/file/clipboard with a preview, export in JSON/YAML… feels much smoother now.

I was going to say, everybody is saying it's super dead since ages now :)

Perfect typo!

Mockoon - Implement rate limiting with custom templates and rules Learn how to implement rate limiting in your Mockoon APIs using custom templates and rules to control request frequency and protect your endpoints

Simulate real-world rate limits in your mock APIs 🛡️

Small but useful improvement in Mockoon v9.3.0, you can now switch the request logs to show full timestamps instead of relative times (“2 minutes ago”).

Perfect for debugging or when you need precise request tracking

Fascist lock-in is the new vendor lock-in!

📖 Recap: mockoon.com/blog/mockoon...

#Mockoon #WeAreDevelopers #DevTools

Isn't it a mainstream opinion?
Backend architecture didn't evolve much in the past 20 years, while frontend drastically changes (and back) every 6 months or so.
As most backend eng I know say: "You do frontend? I could never do this shit".

They had incentive in place in the past.
Year ago I received 2 years of free storage after reaching a certain level (each review/photo posted gives some points). They should do this more often.

Wrapping up two amazing days at @wearedevelopers.bsky.social!
Tons of demos, great dev chats, and yes, I lost my voice 😅
