Since.dev

Since.dev is the changelog of the internet. It tracks every package, AI model, API and runtime as it changes, finds the exact file and line each change breaks in your code, and opens the pull request that fixes it. Packages ship breaking majors. AI models retire on a date. APIs remove fields. Runtimes reach end of life. Since records each change with its source, shows the days left and the replacement, and checks every fix before the pull request opens. Your team reviews and merges. Nothing merges or deploys on its own. Use it from the dashboard, the HTTP API, or one line in your coding agent's MCP client.
