Product Description
/dev/fast offers a range of services designed to enhance the software development process for AI-heavy teams. Their main product offerings include:
-
/dev/fast/review: This is a reimagined code review tool that allows developers to review pull requests (PRs) that are "10x the size in half the time." It emphasizes a focus on architecture rather than implementation details, streamlining the review process.
-
/dev/fast/trace-storage: This service provides a private storage solution that captures every agent run, making it queryable in code. It ensures that all storage is tied to version control, enhancing security and traceability.
-
/dev/fast/tokens: This tool is designed to optimize token costs, enabling teams to "build more with less" by effectively analyzing and managing their token expenditure.
-
/dev/fast/code-storage: A git server that operates on object storage, offering high reliability for code storage needs.
These offerings are tailored for engineers at ambitious companies that are building with AI agents, as well as platform teams managing high-volume parallel processes. The services are backed by Y Combinator, indicating a strong foundation and support for innovation in the software development landscape.
