Monitor APIs and dependencies for changes and automatically generate fix proposals via pull requests, keeping your code always up to date.
What is Since.dev?
Since.dev is an infrastructure platform designed to transform application maintenance through the concept of self-healing software. Its primary function is to continuously monitor a project's external dependencies, such as APIs, software packages, SDKs, and artificial intelligence models. When the system detects a relevant change in these external sources—such as an endpoint deprecation or a new library version—it automatically generates fix proposals in the form of draft Pull Requests (PRs).
The operation of Since.dev is structured into a four-stage cycle: monitoring, impact analysis, repair, and review. In the first phase, the tool tracks sources such as npm, PyPI, GitHub, RubyGems, or OpenAPI specifications. Upon identifying an update or a change in an API contract, the system analyzes the user's code to pinpoint exactly which parts are affected. Utilizing advanced language models like OpenAI, Anthropic, or AWS Bedrock, the platform prepares a corrective patch based on official documentation and the dependency's migration guides.
This tool is especially useful for developers and engineering teams managing multiple integrations who want to prevent their applications from breaking due to third-party changes. Key technical capabilities include:
- World State Monitoring: Allows AI agents to verify external facts and updated versions before executing actions, preventing errors based on obsolete data.
- Automated Dependency Management: Identifies changes in library behavior and proactively proposes compatibility solutions.
- Integration via MCP and Webhooks: Facilitates the communication of detected changes with other tools and agents through the Model Context Protocol or signed APIs.
- Human Review Control: The system does not perform automatic code merges or deployments. Every suggested fix is subject to the existing CI (continuous integration) checks in the repository and requires final validation by the developer.
By integrating Since.dev into the workflow, teams drastically reduce the time spent chasing changes in external documentation. The platform allows for a direct connection to a GitHub repository to gain a clear view of which code needs updating, providing detailed context for every proposed patch. It is a solution aimed at improving software resilience and developer productivity, ensuring that code maintenance is an assisted, efficient process rather than a reactive manual task.
Since.dev features and use cases
How to use Since.dev
Since.dev FAQ
What is Since.dev and how does it benefit my development team?
Since.dev is a tool that monitors your dependencies and APIs to automatically generate fix proposals via pull requests whenever it detects external changes.
Does Since.dev automatically push changes directly to my production code?
No, the tool only prepares draft pull requests. You always maintain final control, allowing you to review and merge changes only after they pass your own testing suite.
What types of elements can Since.dev monitor to detect changes?
You can monitor software packages, repositories, API specifications, public web pages, and status feeds to stay informed about any updates or breaking changes.
What does the "Unknown" monitoring status mean within the platform?
This status indicates that there is no previous value available for comparison or that the source has not published the requested field; however, it doesn't necessarily mean that no changes have occurred.
Can I use my own AI model keys with Since.dev?
Yes, users on Pro and Studio plans can connect their own API keys from Anthropic, OpenAI, or AWS Bedrock to handle code repairs directly.
Do I need to manually add every dependency in my project?
No, that isn't necessary. The tool automatically detects compatible public dependencies as soon as you connect your GitHub repository for the first time.
What happens if my AI agent is offline for a period of time?
Since.dev uses a durable cursor that allows your agent to resume activity from its last confirmed state and process all accumulated changes sequentially.
How can I request a different fix in a proposed repair?
You can request revisions by commenting on the GitHub pull request and mentioning the app, or by making specific adjustments directly from your terminal.
