Know what your coding agents built before you ship
Every agent session becomes a delivery with its brief, task tree, agent runs, code revision, tests, and screenshots kept intact from first instruction to merge.
Each claim an agent makes is pinned to a specific task, delivery, and commit, so you review proof rather than a status message.
See what every agent is doing and what work remains before you ship, instead of piecing together terminals and chat logs.
Install a plugin into Codex, Claude Code, or another harness, and each conversation connects to Blume on its own.

Open-source control plane for orchestrating coding agents
Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
