// the review workbench & speed-first IDE for AI-generated code.
px0 is a review workbench and speed-first IDE built for AI-generated code. It turns your browser into a zero-latency console with native Git and GitHub integrations, instant search across massive codebases, in-place quick fixes, and seamless handoff to local AI coding harnesses.
Run bare px0 to launch a unified dashboard across all your repositories and pull requests. With worktree-backed PR isolation, 1-click agentic rebase, and complete GitHub control, you never have to cycle between terminals, local clones, or external review tools.
~/.px0/repos/px0no clone overheadRun bare px0 to open your review dashboard on a single port. Jump into local repositories, switch between projects in browser tabs, keep unsubmitted review drafts across sessions, and return with ▦ without touching external terminal windows.
When pull requests diverge or fall behind base branches, click Rebase with AI directly next to the merge status pill. Your local coding harness replays commits, resolves conflicts, and force-pushes safely using lease protection.
Execute full pull request lifecycles without opening web browsers or separate tools: inspect merge-base diffs, draft inline comments (Alt+R), batch-apply fixes with AI, submit formal verdicts, and squash-merge with AI commit rewriting.
Anchor multi-turn conversations to code with Alt+T. Watch tools execute live over Server-Sent Events, or queue quick inline fixes with Alt+E and apply them all at once.
I have updated ResolveToken to check cfg.GitHubToken, then inspect GITHUB_TOKEN and GH_TOKEN before falling back to the gh CLI.
if tok := os.Getenv("GH_TOKEN"); tok != "" {
return tok, nil
}func (p *Provider) Authenticate(r *http.Request) (*Token, error) {Validate empty bearer header and return ErrMissingBearer error early
Anchor conversations to code ranges with Alt+T or line gutter icons. Stream real-time tool steps and replies over Server-Sent Events, preserved locally in atomic disk transcripts that survive restarts.
Highlight code in diff or source views, press Alt+E, and stage edit prompts across multiple files. Review queued comments in the Threads drawer and apply all at once with Mod+Enter.
Connect natively to Claude Code, Cursor Agent, Antigravity, or OpenCode. Switch models or harnesses mid-thread with automatic session resume and transcript replay.
Watch your agent read files, write diffs, run test suites, and execute bash commands in real time with collapsible tool step cards and instant syntax-highlighted previews.
Spin up on any remote server, cloud instance, or runner in under a millisecond. Inspect and search remote codebases directly in your local browser without configuring SSH keys, forwarding ports through flaky sessions, or installing heavy remote desktop suites.
$ px0 -host 0.0.0.0 -port 7777 ~/work/repo$ px0 -no-open -port 8080 /workspace$ docker run -p 7777:7777 -v $(pwd):/src px0:latest$ px0 -base-path /rev-123/ -host 0.0.0.0 ~/workRemote code editors install gigabytes of node runtimes and background server processes on the remote machine. px0 runs as a single lightweight binary, serving directly over HTTP without requiring you to maintain SSH shell sessions.
Pass -host 0.0.0.0 or -port 7777 to bind the web console. Access from any browser on your laptop, iPad, or phone across your private VPN, Tailscale mesh, or Cloudflare Tunnel with pooled gzip compression.
Exploration is strictly sandboxed: safePath rejects directory traversal attempts, host header checks protect against DNS rebinding, and external stdlib jumps require explicit allowlisting. Agent editing is protected by origin verification: requests are accepted only when opened by IP address or localhost, and strictly refused through public tunnel hostnames.
The code navigation, search, outline, and reading tools you reach for a hundred times a day, done in milliseconds, in a UI that renders only the lines you can see.
Files, symbols, and a full-tree regex scan behind three chords. Ranking favours basenames, word boundaries, and camelCase humps, the way fzf feels.
Jump to functions, types, constants, and caller trees across files with Ctrl+Shift+O. Built-in regex outline generates instant symbols even when language servers are inactive.
Direct integration with Claude Code, Cursor Agent, Antigravity, and OpenCode. Tabs reload automatically in place with zero manual git stashing.
Read-safe by default, with instant in-place editing via Ctrl+E and Ctrl+S saving when an agent prompt is overkill. Classic text selection across lines and diffs with Alt+E agent dispatch and Alt+C references.
Full GitHub Flavored Markdown with syntax-highlighted code fences and bi-directional scroll sync. Inspect images with zoom/pan, contrast modes (b), pixelated toggle (p), and lightbox.
Windowed tokenizing with Chroma...
Opening a 400,000-line file costs the same as a 10-line one. Only the visible window plus 24 rows of overscan is mounted; scrolling recycles rows with a single transform.
Native tokenizing through Chroma. The server lexes a 1,000-line window padded with 400 lines of context, never the whole file, and caches rendered HTML under a 512 MB LRU budget.
Zero-config detection on $PATH and standard binary folders. Spawned lazily on first request, stopped on exit. Click the status bar hint for automatic installation recipes.
Spin up on cloud VMs, Docker containers, or CI runners with -host 0.0.0.0. The remote host pays strictly ~20-30 MB server memory, while custom subpaths (-base-path) support reverse proxies and multi-tenant ingress.

Tokyo Night by default, plus Paper, Catppuccin, Dracula, GitHub Dark, Gruvbox, Monokai, Nord, One Dark, Rose Pine, and Solarized. A theme is one CSS file of tokens.
HTML, CSS, and JS are embedded with go:embed. No Electron, no Node, no CGO, no system libraries. Copy it to a box and run it.

After 15 seconds without requests, px0 automatically frees memory back to the host kernel (~20-30 MB server RSS). Combined with bounded DOM virtualization (~80-150 MB client tab), total footprint stays ~100-180 MB.
px0 is a review workbench and speed-first IDE built for AI-generated code. Run bare px0 to open the workbench, pass a folder (px0 <dir>) to jump into code, or review any pull request URL (px0 <pr-url>) in an isolated worktree.
Pass any GitHub PR URL to inspect scoped merge-base diffs and draft line comments in milliseconds.
Launch bare px0 for a unified cockpit. Enjoy 1-click agentic rebases and complete GitHub control without switching tools.
Anchor conversations to code with Alt+T and stream live tool execution over Server-Sent Events.
Read through massive trees like the Linux kernel with virtual-row scrolling and instant symbol search.
Run on any cloud VM or CI runner over a single HTTP port without SSH keys or port forwarding.
Stage per-file ticks in the sidebar, browse recent commit diffs, inspect split diffs, and generate AI commit messages.
Review PRs, anchor conversation threads directly to code, and watch agent tool steps execute live over Server-Sent Events.
Anchor conversations to lines or diff ranges with Alt+T. Stream real-time file edits, bash commands, and tool calls over Server-Sent Events, preserved locally in atomic disk transcripts.
