Since.dev

Since.dev is building self-repairing software for a world that never stops changing.

Modern software depends on APIs, SDKs, packages, and AI models that evolve independently of your code. A service changes its behavior, an endpoint disappears, a model gets retired—and software that worked yesterday can fail without a single commit.

We close the gap between what changed outside your code and what needs to change inside it. Since monitors external dependencies, assesses their impact on your repository, and prepares targeted repairs as draft pull requests. Your existing CI checks the changes, and your team decides what ships.

For AI agents, Since delivers the same change evidence through API, MCP, and webhooks, helping them work from current information instead of outdated assumptions.

Our mission is to make adapting to change a built-in capability of software, so keeping it working takes less human intervention.

FEATURES
Dependency Monitoring: Keeps an eye on the external APIs, SDKs, and AI models your app relies on.
Change Detection: Spots when external services change or retire features before they break your App.
Impact Analysis: Checks exactly how external updates will affect your specific codebase.
Auto Repairs: Creates draft pull requests with the necessary code fixes already written for you.
Verification: Uses your existing CI process to test the fixes before anyone merges them.
Agent Integration: Provides real-time updates via API so your AI agents always have the latest info.
Human Control: Ensures your team stays in charge by letting you review and approve every change.
