Meet Opaline

Opaline collects Claude Code and Codex sessions into a shared workspace for understanding how a team uses coding agents. Users can browse work across repositories, follow conversations and tool calls, and examine model usage, token consumption, and API costs alongside the session that produced them. The product was previously called Rudel.

An open-source command-line client discovers local sessions and lets users choose which repositories to connect. After confirmation, it uploads existing sessions and configures future synchronization. Transcripts can include prompts, responses, source code, and tool output, so repository selection is also a data-sharing decision. Disabling synchronization stops future uploads without removing earlier records. The resulting history helps teams investigate difficulties and compare approaches to recurring development work.
