Two OSS products on one rrweb substrate: tracelane (self-contained HTML test-failure replays for WDIO/Playwright/Cypress) + peek (local-first browser-session forensics + repro for AI coding agents, over MCP). No SaaS, no telemetry, local-first.
2 files for Codex, OpenCode and Claude Code: rrweb-stack AGENTS.md, rrweb-stack CLAUDE.md — 2,680 tokens loaded in every session.
