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.

Chrome's Prompt API lets web developers call Gemini Nano — Google's compact, locally-running language model — directly from JavaScript, without any server requests after the initial model download. The API accepts text, audio (AudioBuffer or Blob), and visual inputs (images, canvas elements, video frames), returns streaming text responses, and supports JSON Schema-constrained structured output for reliable data extraction. Sessions are created via LanguageModel.create(), with each session maintaining a token-aware context window that prunes older messages automatically while preserving system prompts. The Prompt API complements other Chrome AI primitives including the Summarizer, Writer, Rewriter, Translator, and Language Detector APIs — all running fully on-device. Model requires 22GB+ free disk space for the initial download; subsequent use works offline. This is a meaningful shift for web AI. Developers can now build privacy-preserving AI features — local transcription, smart autocomplete, content classification, on-page summarization — without touching a cloud API or paying per-token costs. Currently supports English, Japanese, and Spanish. Available via Chrome's Origin Trial program with broader rollout expected through 2026.
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.”
“The JSON Schema structured output is the feature I've been waiting for — finally you can extract clean data from user-typed text without a backend. The 22GB download is a real onboarding hurdle, but once the model is cached, the latency is basically zero compared to cloud APIs. This changes the math for privacy-sensitive consumer apps.”
“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.”
“A 22GB model download as a prerequisite for a web feature is going to have terrible adoption outside of developer demos. Most users won't have that space or patience, and the English/Japanese/Spanish-only limitation rules it out for global products. Wait for the model to shrink before betting your product on this.”
“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.”
“On-device inference in the browser is the endgame for consumer AI. No API keys, no latency, no data leaving the device — this is what private-by-default AI looks like. The browser becomes the AI runtime, and Google just got there first. The model size issue is a 2026 problem; by 2027 it'll be 2GB.”
“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.”
“Real-time image and canvas analysis directly in the browser opens up creative tooling that wasn't possible without a backend. Think live design feedback, style detection from reference images, or on-the-fly alt-text generation — all without a cloud API call. The streaming responses make it feel snappy enough for interactive UX.”
