mazu-web

A local browser UI for Mazu -- the core coding-agent CLI stays terminal-first and dependency-light; this is a separate, optional companion for people who'd rather work in a browser tab.

Ships as its own package (mazu-web, console script mazu-web) so Mazu's core install never pulls in a web framework just to run mazu chat in a terminal.

What it does

Full parity with the terminal command surface -- every route calls straight into the same mazu package classes (CheckpointManager, MemoryStore, RunStore, the router, run_autonomous, run_explore, run_council, diagnostics) the CLI itself uses. This UI is a different way to reach the same operations, not a second implementation of them.

• Chat -- the same turn logic as mazu chat, streamed over Server-Sent Events instead of printed to a terminal.
• Run -- one-shot autonomous tasks (mazu run), streamed.
• Explore -- parallel branch comparison (mazu explore), streamed.
• Council -- ask multiple models independently, one lead synthesizes (mazu council), streamed.
• Checkpoints -- timeline, diff, compare, inspect, prune, branch-from, and one-click rollback.
• Memory -- search, pin/unpin, edit, forget, stats, "why would this retrieve", find/merge duplicates.
• Skills, Runs (+ compare-branches), Router, Usage, Action log, Models, Doctor, Config -- all full read (and write, where the CLI itself allows it).
• Curator -- an opt-in, fully autonomous background process that maintains Mazu's own state (memory, skills, run/checkpoint history, usage, config, council roster, action log) using its own, completely separate API key, matching mazu curator .... Inert until configured; every mutation is reversible and logged with a rationale.
• Init / Setup -- works against a directory that isn't a Mazu project yet; an in-page banner and a Config-tab form do what mazu init/mazu setup would from the terminal.

Run and Explore and Council share one server-wide lock: all three wrap print()-only agent functions via sys.stdout redirection, which is process-global, not thread-local -- two concurrent captures would corrupt each other's output. Starting a second one while the first is still running gets a 409, not a silently queued mess.

Install

pip install mazu-web

Depends on the core mazu package (mazu>=0.22.0, pulled from PyPI automatically).

Run

cd your-project        # doesn't need to be `mazu init`-ed first -- the browser handles that
mazu-web                # http://127.0.0.1:8765

mazu-web --host 127.0.0.1 --port 8765 --model deepseek:deepseek-chat --shell-allowlist git,npm,pytest

Binds to 127.0.0.1 only by default -- there is no authentication, so don't pass --host 0.0.0.0 or otherwise expose this beyond your own machine.

Development

pip install -e ".[dev]"
pytest
