GitNexus is a zero-server code intelligence engine that runs entirely in your browser. Drop in a GitHub repo URL or ZIP file and it builds an interactive knowledge graph covering every dependency, call chain, cluster, and execution flow — no backend, no telemetry, no data leaving your machine. The integrated Graph RAG Agent lets you query the codebase structure with natural language, getting structurally-aware answers instead of naive vector similarity matches. What sets GitNexus apart is precomputed structure: it clusters, traces, and scores at index time so agent tool calls return complete architectural context in a single lookup. Claude Code, Cursor, and Codex integrations via MCP give your AI coding assistant a genuine understanding of the codebase before it touches a single file — stopping the classic failure modes of missed dependencies and blind edits that break call chains. The project has grown to 28,000+ stars and 3,000+ forks with 45 contributors, which is impressive for an indie tool with no VC backing. The zero-server architecture means it works on private codebases without requiring any cloud trust. For teams who've grown frustrated with AI assistants that don't understand their project's structure, GitNexus is the context layer that's been missing.

The coding agent that sees your live app — DOM, console, and all

Stagewise is a developer browser with an AI coding agent baked in. Unlike agents that only read source files, Stagewise gives the agent live access to your app's DOM, console output, and debugger state — the same context you'd have manually inspecting a bug. That runtime visibility makes for far more accurate edits on existing frontend codebases. The workflow is simple: open your app in Stagewise, describe what you want to change, and the agent modifies source files while watching the live result. You can also point it at any external website to extract components, design tokens, and color palettes for reuse in your own projects. IDE integration means changed files appear in VS Code or your preferred editor immediately. Built by YC alumni Glenn Töws and Julian Götze, Stagewise is open-source (TypeScript, 97.6% of the codebase) with a BYOK model supporting all major LLM providers. Pricing tiers — Free, Pro ($20/mo), Ultra ($200/mo) — scale with usage. It launched on Product Hunt with 107 upvotes and continues to gain traction in the vibe-coding and frontend agent communities.
Reviewer scorecard
“The MCP integration for Claude Code and Cursor is the killer feature — this is the architectural context layer those tools have always lacked. Precomputing the graph at index time so agents get full call chain context in one lookup is a smart design decision that pays off in real usage. 28K stars says the community agrees.”
“Browser-native debugging context for a coding agent is a genuinely different approach. When the agent can see your console errors and DOM state in real time, it makes dramatically better edits than agents that only see source code. The reverse-engineering feature — extract components and design tokens from any site — is something I've been doing manually for years. BYOK keeps costs transparent.”
“Running a full knowledge graph build in-browser sounds impressive until you try it on a 200K-line monorepo. The zero-server pitch also means zero persistence — re-index every session. And Graph RAG on code is a genuinely hard problem; impressive demos on small repos may not hold up on enterprise-scale codebases where the graph gets exponentially complex.”
“A $200/month Ultra tier for a browser is a steep ask. The core proposition — agent with console access — isn't fundamentally different from what you can achieve with a well-configured Playwright-based agent. Frontend-only scope is a real limitation. Backend bugs, database issues, or server-side rendering problems won't benefit at all. Niche tool for a specific workflow.”
“Privacy-first code intelligence is a growing enterprise requirement as legal departments wake up to the risks of sending proprietary source code to cloud APIs. GitNexus's client-side architecture is a direct answer to that concern. The Graph RAG approach also feels like the right bet as coding agents mature and need richer structural context beyond flat vector embeddings.”
“The browser will become the primary agent runtime for web development. Having the agent native to the browser — with DOM access, console context, and live preview — isn't a novelty, it's the correct architecture. Stagewise is early but directionally right. The design-token extraction capability points toward agents that understand visual intent, not just code structure.”
“The interactive graph visualization is genuinely useful for onboarding onto an unfamiliar codebase — I can see the whole call structure at a glance before diving in. Drop a ZIP and get a clickable architecture map is a much better DX than reading README files. This is the kind of tool I'd use even without the AI bits.”
“Being able to point at a website and say 'build me something that looks like this' — with the agent actually extracting the real color tokens and component patterns rather than guessing — is genuinely useful for rapid prototyping. The fact it connects back to my actual codebase for permanent edits closes the loop that most browser dev tools leave open.”
