Since.dev is a platform for monitoring software and making it self-healing; it monitors APIs, packages, SDKs, and models, then converts changes to supported dependencies into pull requests (PRs) for fixes. The platform allows you to connect a GitHub repository to see what has changed, find the affected code, and review a supported fix. The workflow includes detecting external changes, determining their impact on the code, preparing a small supported fix, and then reviewing it through the user’s CI. Sources that can be monitored include npm, GitHub, PyPI, Rust, OpenAPI, and RubyGems. It also supports monitoring API changes, SDK updates, deprecations, and provider changes. The API Contract feature links a documented API change to the calls that use it, with the ability to review a supported fix for an endpoint, parameter, or version, An example of this is changing the endpoint from /v1/messages to /v2/messages within src/integrations/messages.ts. The platform provides supported fixes and draft PRs, while testing is conducted within the user’s repository and the user chooses what to ship; nothing is automatically merged or deployed; Draft PRs use the user’s existing CI system, with the ability to request modifications and review the updated patch within the PR itself. Since.dev also offers the World State feature, which allows agents to verify their assumptions against the latest recorded observation before performing any action; the external state includes facts, versions, and service provider conditions. The Verification feature allows you to check whether recorded information remains valid without performing a new fetch, noting that an “Unknown” status does not necessarily mean the information has not changed; For example, if `example-sdk.version = 19.0.0` has changed to `20.0.0`, the agent receives evidence for review when the observation differs, and must verify the observation timestamp and source status. The platform also offers Shared Evidence, where the public source is checked once for everyone, while each Watch retains its own instructions and notifications; users can specify the changes that matter to them, such as API changes, security fixes, and new releases. Since.dev allows agents to submit the changes they need via MCP, HTTP API, or Signed Webhooks, and uses Durable Cursor to preserve the user’s position, so that a read operation does not move the cursor, while Acknowledge is executed after processing and then the work is resumed from the remaining position. It also supports issue tracking, fact-checking, coverage analysis, and change tracking through the tools used by the agent. The MCP setup includes the URL https://api.since.dev/mcp with an Authorization header, It also provides Integration Guides, which offer context for each change, including the statuses “breaking,” “deprecated,” “behavioral,” “additive,” and “advisory.” The official page explains that monitoring sources are checked on a scheduled basis rather than as a real-time feed, and that coverage includes packages, repositories, specifications, public pages, and supported status sources, while it does not include private sources, those protected by login, or those closed to automated reading.
