asciinema for AI coding agents.
Your AI coding agent just made 300 tool calls and changed 14 files. The diff shows what changed. It doesn't show what it read, what failed, or where it looped.
Claude Code and Codex already write a full log of every session to your home folder. Nobody opens it. So I built the viewer.
agentcast turns those logs into one self-contained HTML replay: a timeline, every edit as a diff, every command with its output, errors in red, tokens and estimated cost, and a "blast radius" list of every file the agent touched. Deep links like replay.html#142 so you can point a reviewer at the exact step.
Pure Python, zero dependencies, nothing leaves your machine. Secrets scrubbed by default.

If you ship agent work for clients, this is the receipt.
