---

Opaline is an MIT-licensed CLI that gives PostHog-style session analytics — token cost and usage — for Claude Code and Codex, and is self-hostable. It is a mature project (created February 2026, 298 stars), not a brand-new drop; the recent event is its rename and relaunch from rudel to Opaline. It has been maturing since February 2026.

## Provenance

- MIT (OSI-open); 298 stars, created 2026-02-16, last push 2026-09-21; a CLI providing PostHog-style session analytics (token cost and usage) for Claude Code and Codex; self-hostable (WebFetch 2026-09-24).
- Surfaced via studio discovery in the 2026-09-24 pass.
- Anti-hype note: this is a mature project (created 2026-02-16, 298 stars), not a new ship. The recent event is the rudel→Opaline rename/relaunch; the repository still resolves at the rudel URL.
- Curated from the GTM Stacker signal registry (2026-09-24 pass); license/facts independently verified 2026-09-24.

## Why it matters for a GTM stack

As a team standardizes on coding agents, the spend and usage go dark — you know the seats cost money but not which sessions burned which tokens. Opaline gives that PostHog-style session view for Claude Code and Codex: cost and usage per session, self-hosted so the telemetry stays yours. For a lead deciding whether the agent budget is paying off, that observability is the difference between a gut feeling and a usage curve. The honest read: this is not a hot new tool riding a launch — it is a February-2026 project (298 stars) that just rebranded from rudel to Opaline, so evaluate it as a maturing option, and expect docs to reference both names during the transition.
