I open sourced my API auto repairing tool for free
Building and maintaining APIs can be exhausting. Between schema changes, breaking updates, and unexpected payload mismatches, things constantly break in production. That is why I built and open-sourced Repairo —a free, automated tool designed to detect and auto-repair API issues before they cause downstream failures. Why I Built Repairo Modern microservices architectures rely heavily on APIs…
Automating the repair of API issues is a labor-intensive task. Repairo, an open-source tool, simplifies this process by automatically detecting and fixing API problems before they lead to downstream failures. The tool was developed to address the challenges faced in modern microservices architectures, where small changes in data contracts can cause unhandled exceptions or failed requests.
Repairo operates by intercepting failing requests, examining the schema divergence, and applying safe auto-corrections in real-time. This eliminates the need for manual patch writing or late-night debugging sessions. Key features of Repairo include automated schema healing, which identifies discrepancies in incoming and outgoing payloads and maps them to the expected types, and zero-downtime patching, which ensures services continue to run smoothly without requiring immediate manual deployment for minor drift issues.
The tool is designed to be lightweight and extensible, making it easy to integrate into existing API gateways and middleware pipelines. Repairo is completely open source, allowing anyone to access the repository, review the code, or contribute to its development. The repository is available at the [Repairo GitHub Repository](https://github.com/adityacs50-lab/Repairo). The developers encourage contributions, feature requests, and feedback to continually improve the tool.
