Blume

Know what your coding agents built before you ship

Delivery-based tracking

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.

Evidence-based review

Each claim an agent makes is pinned to a specific task, delivery, and commit, so you review proof rather than a status message.

Multi-agent visibility

See what every agent is doing and what work remains before you ship, instead of piecing together terminals and chat logs.

Agent plugin integration

Install a plugin into Codex, Claude Code, or another harness, and each conversation connects to Blume on its own.
