Opensource IDE For Exploring and Testing API's (lightweight alternative to Postman/Insomnia)
What it does
Bruno is a free, open-source desktop app that lets developers test and explore APIs — the connections between software services — without needing an internet connection or a cloud account, storing all work as plain files on the user's own computer. It positions itself as a privacy-focused alternative to popular tools like Postman and Insomnia, which typically require accounts and store data in the cloud.
Why it matters for PMs
With nearly 41,000 stars and growing backlash against Postman's shift to cloud-required, subscription-based pricing, Bruno signals strong market demand for developer tools that prioritize data ownership and offline use — a real competitive gap to watch. For founders and investors, this project demonstrates that 'de-cloud' positioning can be a powerful differentiator in the developer tools market, where trust and workflow control are increasingly valued.
