awewarm-hub: Multi-tenant Hub Server
One always-on box keeps a whole team's subscription windows warm.
The multi-tenant hub server for awewarm: many users, one server, one-time invites — each user's secrets staying on their own machine.
English · 简体中文
Real case: a five-person team on one $5 VPS. Everyone's subscription plans stay warm around the clock on the box that never sleeps — while every API key stays on each member's own laptop.
awewarm-hub splits the roles in two:
- Operator (this machine, the 24/7 box):
awewarm-hub serve+ the admin commands below. You mint one-time invite codes and hand them out. - Users (their own machines, plain open-source awewarm only):
awewarm remote connect <url> --invite awi_..., thenawewarm config set <id> --remote. They never need this package.
Install
Requires Python ≥ 3.9:
pip install awewarm-hub # brings awewarm with it
Quick Start
Let an AI agent set it up
Working in Claude Code, Codex, or another coding agent? Tell it:
Read https://github.com/wehuman01/awewarm-hub/blob/main/README.ai.md and follow it to set up your awewarm-hub server.
The agent installs the CLI, checks status and tenants read-only, and mints invite codes on your request. The resident serve process itself stays in your terminal (or systemd) — an agent never backgrounds it.
Manual setup
awewarm-hub serve # listens on 127.0.0.1:8790, data at ~/.awewarm-server
awewarm-hub invite --note alice # prints awi_... (one use, 48 h)
awewarm-hub status # capacity, invite counts, tenants, serve liveness
awewarm and awewarm-hub
Two packages, two roles, same MPL-2.0 license and the same wehuman01 org:
| Package | Who installs it | What it does |
|---|---|---|
| awewarm | everyone (each user's own machine) | schedules warm-up requests; awewarm serve covers one solo server |
| awewarm-hub (this package) | the operator only (the 24/7 box) | multi-tenant serving: tenants, one-time invites, quotas, revoke/restore |
The engine underneath (WarmServer, schedule, transport, the HTTP handler core) comes from the awewarm pip dependency, pinned to its minor version so the wire protocol stays in lockstep with the open-source client. Expose the hub through a cloudflared tunnel (free TLS, no open inbound ports, your origin IP stays hidden) exactly like a solo awewarm server — see awewarm's README → Remote Server. A systemd user unit is the same shape, with ExecStart=awewarm-hub serve:
[Unit]
Description=awewarm-hub serve
After=network-online.target
[Service]
ExecStart=awewarm-hub serve
Restart=on-failure
[Install]
WantedBy=default.target
systemctl --user enable --now awewarm-hub (with loginctl enable-linger $USER on headless boxes).
Commands
awewarm-hub serve [--data-dir/--bind/--port] # the resident hub server
[--max-tenants/--max-conns-per-tenant/--max-machines/--tick-seconds]
awewarm-hub status [--details] # capacity, invite counts, tenants, serve liveness
awewarm-hub invite [--note <who>] [--expires-hours N] [--machines N]
awewarm-hub list users [--api|--reveal|--json] # tenants: health, usage, machines, joining code
awewarm-hub list invites [--reveal|--json] # every minted code: pending/used/revoked/expired, its machine cap
awewarm-hub revoke <awi_...> # kill an invite: pending stops pairing, used suspends its tenant (reversible)
awewarm-hub restore <awi_...> # undo a revoke
awewarm-hub config [--data-dir /data|--unset] # default data dir for this machine
awewarm-hub self-update [--check] # upgrade from PyPI
How It Works
Each tenant gets a private workspace under tenants/<id>/ (connections, state, RAM keyring — invisible across tenants). tenants.json stores SHA-256 hashes of tenant tokens, so pairings survive a restart; invite codes are kept in the clear so the operator can recover one already sent (list invites --reveal) — anyone who can read the data dir can use a pending invite, so guard it. The invite code is the one ledger of authorization: revoke awi_... kills a pending code or suspends the tenant that used it (token rejected, connections stop ticking, capacity slot freed), and restore awi_... undoes either — machine pairings are untouched, so the round-trip is lossless. A machine cap is stamped into each invite at minting (invite --machines N, defaulting to serve --max-machines); to give an online user more machines, raise the machines value on their invite row in tenants.json (a running serve adopts the edit) or hand them a fresh code. A light per-tenant rate limit (60 requests/minute) stops a looping client.
One trust rule, stated plainly: the hub fires requests with its users' API keys, so their plaintext keys pass through its RAM. Hub for people who trust the machine's operator (and root); a shared VPS with strangers is not that.
Nothing secret is ever written to disk — API keys live in server RAM and are re-pushed by each user's machine after a restart.
Upgrading from pre-split awewarm serve --hub
The data dir (~/.awewarm-server, or whatever --data-dir/the old hub config --data-dir set) carries over unchanged — tenants, invites, and the persisted data-dir setting all keep working. Stop the old serve, install this package, start awewarm-hub serve. The old spellings (awewarm serve --hub, awewarm hub ...) die with a tombstone in awewarm naming their replacement here.
Upgrading to v0.5.6 (breaking): revoke/restore now address invite codes only — revoke t_... is gone; find the code a tenant joined with via list invites --reveal. The first launch after upgrading migrates tenants.json once: tenant-level suspensions move onto their invite's revokedAt, and any invite row minted before codes were stored on disk is dropped together with the tenant it produced (its token dies; its workspace stays — re-pair with a fresh invite). Upgrade the package and restart serve together, so both processes speak registry v2.
Config
awewarm-hub config [--data-dir /data] persists the default data dir on the hub machine (the flag overrides once; --unset clears it). The default is ~/.awewarm-server, shared with awewarm's solo server. Inside it: tenants.json (token hashes, invite codes, the serve record with caps/bind/version/start time) and one private tenants/<id>/ workspace per tenant. Serve stamps its caps into tenants.json at launch so one-shot CLI processes on the same box read the same numbers; a data dir whose serve never launched says "caps unknown" instead of guessing.
Self-Update
awewarm-hub self-update # upgrade to the latest release
awewarm-hub self-update --check # show versions only
Development
python3 -m venv .venv && source .venv/bin/activate
pip install -e ../awewarm -e . # the open-source engine, editable, plus this package
python3 -m unittest discover -s tests
awewarm-hub -v says editable (with the git state) when running from this checkout; pip's recorded metadata freezes at pip install -e . time, so re-run it after a version bump to keep pip show in sync. awewarm-hub self-update refuses on a checkout — pull and re-install instead.
The source repository is wehuman01/awewarm-hub (open, MPL-2.0); releases are built and published to PyPI on tag push. See docs/CONTRIBUTING.md for the engineering doctrine and docs/CHANGELOG.md for release history.
