Lazyagent – A TUI for monitoring AI coding agents

Running multiple coding agents could make user losing track of what they were doing. Once subagents start spawning other subagents, basic questions get hard to answer: what is running right now, what tool did it just call, did the child agent actually do what the parent asked.Lazyagent is a terminal TUI that collects events from Claude Code, Codex, and OpenCode and shows them in one place.
It groups sessions from different runtimes by working directory, so Claude and Codex runs on the same repo appear under the same project. From there you can:- Filter events by type: tool calls, user prompts, session lifecycle, system events, or code changes only.- See which agent or subagent is responsible for each action. The agent tree shows parent-child relationships, so you can trace exactly what a spawned subagent did vs what the parent delegated.- View code diffs at a glance. Edit, Write, and apply_patch events render syntax-highlighted diffs inline, with addition/deletion stats. No need to switch to a terminal or git to see what changed.- Search across all event payloads with full-text search. Useful when you know a file was touched but not which agent or tool did it.- Watch a run in real time, or go back through a completed session to trace.For me, it's quite useful to be able to filter and verify which agents only play the roles I want.I hope you find it useful too!github.com/chojs23/lazyagent
