Kaval - Verify what your AI agent believes before it takes action

Your agent's worst mistakes won't look like mistakes. They'll be confident actions on cached facts, stored fields, and RAG chunks that quietly went stale. Kaval re-derives the truth the instant before your agent acts and returns a verdict to branch on: act, or don't. One MCP call, a typed pass/block with the proof.

Rebo - Your remote coding agent that turns tasks into PRs

Rebo reads your tasks, edits your repo with GPT-5, runs the build, and opens a GitHub PR foRebo is your personal remote coding agent. Describe a task in natural language, pick a repo, and Rebo does the boring parts: creates a branch, edits the code, and opens a PR for you to review. It’s built for solo devs, indie hackers, and small teams who want to ship faster without copy-pasting code into an AI chat all day.r you to review. AI coding agent for individual developers.
