Broccoli is a self-hosted AI coding agent that runs on your own GCP infrastructure and monitors your Linear project board. When you assign a ticket to the Broccoli bot, it reads the ticket, plans an implementation, writes the code, and submits a pull request on GitHub — all without any external control plane. Every diff gets dual review from Claude and Codex before the PR lands. The setup is deliberately friction-minimal: a single bootstrap script handles deployment in about 30 minutes. Your prompts, your data, and your API calls stay on your own infrastructure. There's no SaaS dashboard, no usage fees beyond your own LLM API costs, and no vendor lock-in baked in. For teams that are uncomfortable routing proprietary code through hosted coding agent services, Broccoli fills a real gap. It won't replace senior engineering judgment, but for well-specified tickets — bug fixes, feature additions with clear acceptance criteria, test writing — it closes the loop from ticket assignment to reviewable PR without a human writing a single line.

Euphony is an open-source, browser-based visualization tool from OpenAI that transforms raw Harmony JSON/JSONL chat data and Codex CLI session logs into interactive, filterable timelines. Paste JSON, upload a file, or point it at a public URL — Euphony auto-detects the format and renders a structured conversation view. The tool surfaces conversation-level and message-level metadata through a dedicated inspection panel, supports JMESPath-based filtering for querying large datasets, includes translation support, and can run entirely in the browser without any server dependency. For developers debugging Codex agent runs or analyzing large conversation datasets, it replaces manual JSON parsing. Euphony ships as a web component library so it can be embedded in other tools, and includes a FastAPI backend mode for remote loading and Harmony rendering. It's MIT licensed and available on GitHub at openai/euphony.
Reviewer scorecard
“Self-hosted is the keyword that matters here. You own the infra, the prompts, and the API calls. For any team with compliance requirements or proprietary code concerns, this is the only sane way to run a coding agent that touches your tickets. The dual Claude + Codex review on every diff is a smart trust-but-verify layer.”
“Debugging Codex agent sessions used to mean manually reading JSON in a text editor. Euphony is what that developer experience should have always been — structured timelines, metadata inspection, and JMESPath filtering that actually works on large session files.”
“GCP-only infrastructure means you're adding real DevOps overhead before you get any value. And 'well-specified tickets' is doing a lot of heavy lifting — the hard part isn't writing the code, it's figuring out what to write. Until this handles ambiguous tickets gracefully, it's a tool for teams that already write exhaustive Linear descriptions.”
“This is purpose-built for OpenAI's Harmony format and Codex sessions, which means it's primarily useful if you're already deep in the OpenAI ecosystem. Developers using other agent frameworks get limited value here unless they adapt the format.”
“The self-hosted coding agent model will matter enormously as enterprises get serious about agentic development. Broccoli is early, but the architecture — your infra, your LLMs, your audit trail — is exactly what regulated industries will require. This is what the next wave of enterprise AI adoption looks like.”
“Observability tooling for AI agents is a nascent but critical category. Euphony is a first step toward treating agent session logs with the same rigor we apply to application traces and logs — we'll see a whole category of tools like this emerge over the next two years.”
“The bootstrapped, indie-built philosophy shines through. No VC backing, no SaaS fees, no telemetry. The GCP limitation feels like a constraint the team will work past, but for solo developers or small teams who live in Linear and GitHub, this is a genuinely useful addition to the workflow today.”
“This is deep dev tooling with a specific niche — valuable for AI engineers but not directly applicable to creative workflows. The visualization quality is clean, but most creators won't interact with raw Harmony JSON.”
