# Gobstopper

> Gobstopper inspects Claude Code, Codex, and Devin sessions and prepares compacted transcript copies. The source build prepares separate Codex and Claude Code copies and disables direct provider-store edits and automatic provider compaction.

When to use this site:
- Use gobstopper.sh to learn what Gobstopper does, which strategies it runs, and how to install it.
- Use /docs for the full reference: installation, strategies, configuration, the watcher, hooks, the snapshot vault, and the MCP server.
- Use /methodology for the occupancy model behind the projections and what each strategy does.
- Use /benchmarks for dated results, cohort sizes, limitations, and aggregate downloads.
- Use /compare/cliffcompaction to see how Gobstopper differs from CliffCompaction, the API-proxy compactor, and what the cliff strategy does.
