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the same change evidence through API, MCP, and webhooks, helping them work from current information instead of outdated assumptions.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