Diffly watches your APIs and tells you when something changes—what broke, why it matters, and the fastest way to fix it. Get clear alerts, AI-guided explanations, ready-to-use fixes, and a smooth dashboard. Fewer surprises, fewer hotfixes, steadier releases.
Hey Product Hunt 👋 We built Diffly because our teams kept getting blindsided by breaking API changes. It's frustrating to realize an endpoint drifted only after users start seeing errors. Diffly sits between your app and all the APIs it relies on: we baseline each response, monitor for any schema or behavior changes, and alert you instantly with a clear explanation and a recommended fix. No other tool combines sub‑second monitoring with AI‑powered diff analysis and a smooth, card‑based dashboard. We're most proud that Diffly makes API maintenance boring again—you can re‑baseline or resolve issues in one click and keep shipping with confidence. On a personal note, this is my first fully completed SaaS project as an indie maker, and I'm excited to share it with you all. Excited for your feedback!
