Weatherdeck – a read-only status board for AI coding agent lanes

Moshik21 released Weatherdeck, an open-source, read-only status board that displays the state of AI coding agent lanes from JSON documents pushed over HTTP by any source. Weatherdeck runs on Python 3.9 to 3.14 using only the standard library, one SQLite file and one HTML/JS/CSS page, requires no build step, CDN, telemetry or root access, and is pre-1.0 hobby software with best-effort support. The board marks a source that stops reporting as silent and fogged rather than showing stale data as fresh, and makes no LLM or model call anywhere.

Weatherdeck is a status board for machines and the work running on them a TV or phone page fed by small pushers , not a weather app and not a monitoring or alerting system. What you see. Every picture here is the demo weatherdeck run --demo , with theme=ship-deck on the page address . Its sources are invented and nothing in it is real. - Waiting on you. The amber plate counts the calls that need a person and says how long each has waited. - Honest progress. Progress shows as a percent range where the source gives one for example 38-42% . A lane the board cannot read is counted as "can't tell" the "+7 more" line says 1 , not shown as fine. - A quiet source is named. The lamp by the clock counts live sources. When one stops reporting it reads "2/3 live", and that machine's ship is drawn in fog and labelled silent. - One board for TV and phone. The same page is the open sea on a wide screen and one column on a phone. In the clip, Cinder one of the invented sources stops reporting. Still frame https://github.com/Moshik21/weatherdeck/blob/main/docs/img/tour-still.png . The phone page from a few minutes into the demo, cropped after the ALL FINE tile: the calls, then the problems, then that tile, which is lit only when no call or problem is open and every feed reports. It is an at-a-glance board for work reported by many sources, meant to be left on a TV or a phone: what is waiting on you, what is moving and how far along it honestly is, what got done, what is next, and whether you can trust what you are looking at. - Any tool can leave a card. One small JSON file in a drop directory becomes a status tile; the board only reads it docs/ADDINS.md https://github.com/Moshik21/weatherdeck/blob/main/docs/ADDINS.md . - Any tool can feed it. A source is anything that can send one JSON document over HTTP. Sources are discovered, never configured; machines and items appear on their own. - Checkable. Every push a host receives is one line in its received log weatherdeck received --diff : what each source sent and what changed on the board. - Honest about gaps. A source that stops reporting stays on screen, marked silent and fogged. The board never shows stale data as fresh, and says so when a source is missing. It claims no value for itself or any tool until a number is measured docs/honesty.md https://github.com/Moshik21/weatherdeck/blob/main/docs/honesty.md . - Read-only, local, tiny. Python standard library only, one SQLite file, one plain HTML/JS/CSS page. No build step, no CDN, no telemetry, no root. - Runs anywhere. The same command natively on Windows, macOS and Linux, no admin needed. Run several hosts at once; every page says which host serves it. - Deterministic. No model or LLM call anywhere; the only outbound traffic is an adapter pushing to a host you name. What this is not. It is not a monitoring or alerting system: it never pages anyone, and it shows only what sources push to it. It is not a hosted service: you run it yourself, on machines you choose. And it is pre-1.0 hobby software, open-sourced because it solved a problem the author had: details may change, and support is best effort. You need Python 3.9 to 3.14 an older one stops at startup with a one-line message; the Microsoft Store one is fine for trying it; to run it at logon or run the beat, see docs/runbook-windows.md https://github.com/Moshik21/weatherdeck/blob/main/docs/runbook-windows.md . Nothing to install: run it from a source checkout or the release zip. Get the code by cloning this repository git clone it, then cd into the folder , or by unzipping the zip that scripts/build-package builds from a clone. pip install is not supported yet and stops with a message saying so. Below, weatherdeck means python3 bin/weatherdeck on macOS/Linux and bin\weatherdeck.cmd on Windows cmd or PowerShell . 1. See it with synthetic data. weatherdeck run --demo Open http://127.0.0.1:8787/ http://127.0.0.1:8787/ . Three invented sources report; one stops reporting after about two and a half minutes, shows late from about 2:40 and silent about three minutes after start, so you can see the offline state. Ctrl-C stops it. --port N to change the port. 2. Run it for real. weatherdeck on background; prints the URLs weatherdeck status weatherdeck off The data lives in your per-user data directory --data DIR or $WEATHERDECK DATA to choose another . On Windows, weatherdeck startup install also starts it at every logon, with no admin rights. 3. Send it something. Any tool, one POST from the same machine, no setup needed : curl -X POST http://127.0.0.1:8787/api/ingest -H 'Content-Type: application/json' -d '{ "schema": "lookout.feed", "schema version": "1.0", "source": { "id": "my-laptop" }, "items": { "id": "build", "title": "Nightly build", "state": "running" } }' The schema id reads lookout.feed on purpose: it is the wire name every adapter already speaks, kept unchanged when the product was renamed see docs/feed-spec.md https://github.com/Moshik21/weatherdeck/blob/main/docs/feed-spec.md , "Schema ids" .To feed it continuously, run the example adapter, which turns a hand-edited list plus this machine's vitals into a feed and pushes it to every host in a list: cp examples/adapter/work.example.json work.json cp examples/adapter/sinks.example.txt sinks.txt edit the hosts python3 examples/adapter/push example.py --work work.json --sinks sinks.txt To feed it from your own tool, see docs/adapters.md https://github.com/Moshik21/weatherdeck/blob/main/docs/adapters.md , "Write a pusher for your tool". 4. Let other devices see it. Add addresses to hosts.bind in your config file a LAN address, a VPN range, or both , create a token per source weatherdeck token new my-laptop , and open the page from your phone. Once any token exists, pushes need Authorization: Bearer <token . For a TV, open the page full-screen on any machine that can reach the host, or in kiosk mode on the host itself.The config file is <data /config.json , in the data directory from step 2 weatherdeck status prints that directory; --config FILE or $WEATHERDECK CONFIG names another file . It does not exist until you create it. A minimal one: { "hosts": { "bind": "localhost", "auto:192.168.1.0/24" } } Restart the host after editing it weatherdeck restart . Every key is in docs/hosting.md https://github.com/Moshik21/weatherdeck/blob/main/docs/hosting.md . 5. Remove it. Stop the host with weatherdeck off , then delete the folder you unpacked or cloned and the data directory where weatherdeck status says it is . On Windows, run weatherdeck startup remove first if you ran startup install . Nothing else is installed: no service, no registry entry, no files elsewhere. | | Windows 11 | macOS Apple Silicon | Linux Ubuntu, WSL2 | |---|---|---|---| | Host weatherdeck run , on , ingest | supported | supported | supported | | Python | 3.9 to 3.14 3.8 is not supported | 3.9 to 3.14 3.8 is not supported | 3.9 to 3.14 3.8 is not supported | | Test suite on GitHub's hosted runners first run, 2026-10-16; 433 tests, .github/workflows/test.yml , run by hand | 10 to 13 tests fail on every Python version.

What each release was actually run on is in CHANGELOG.md https://github.com/Moshik21/weatherdeck/blob/main/CHANGELOG.md , with the checks only a person can make a real Safari, iPhone and TV; only the dashboard depth scene has been signed off so far, see docs/device-checklist.md https://github.com/Moshik21/weatherdeck/blob/main/docs/device-checklist.md listed as such.

Packages that bundle an adapter for a specific tool are built from that adapter's own repository, not here. - examples/ : the synthetic demo feeds, a tiny generic adapter and an example host config examples/host/ . Open the static demo: a folder of plain files that shows the board with a recorded feed of invented sources, no server and no Python needed to look at it. It is built in the source repository, not from this package which does not carry the build scripts : there, python3 scripts/build-static-demo writes dist/static-demo/ ; open dist/static-demo/index.html in a browser, or put that folder on any static host. A yellow bar, DEMO: recorded synthetic feed , stays on the screen and says nothing is live. The page replays three recorded frames in order, a slow step every 25 seconds, so the calls, lanes and weather change as they did in the recording with reduced motion it holds one frame and offers a button for the next . To record the frames again, in the source repository, python3 scripts/record-demo-feed . On a TV, a desk screen or a laptop any window 700 CSS px or wider the front door is the open sea /sea , or no route : the fleet on the water at full screen, one ship per machine with its name plate, the headline card for the calls on the left and the log along the bottom, on a 640 x 360 art-pixel stage. Each ship plate carries a quiet badge: how many asks wait on you from that machine, and how many of its lanes are off course or alerting. A ship opens its plan, a place opens its list. The Lists door beside the ? and in a ship's plan bar opens the page board /board , docs/theme-spec.md section 24 : a header with the way back to the sea and the key, a three-state strip needs you, needs attention, all fine , the lanes grouped under the goal they serve, else by project a state word and icon, the job, one sentence, the worker's own notes behind a tap and the sea with a caption for every picture. On a phone the page board is /sea itself. The tv view never shows the page board: there the sea is the whole display. The list below describes the stage's parts one column on a phone with the tv view . 1. Waiting on you the one amber plate : decisions, approvals, capacity and machine problems, with where to act. A critical takes over the bar instead. 2. Trust: a lamp by the clock says how many sources are live and how old the newest report is; a silent source is named there, its machine reads SILENT and its work keeps its state with LAST KNOWN beside it. 3. Machines: a pip and a word each OK, STRUGGLING judged against the machine's own norm, a low disk, ALERT, SILENT, LOST, or ASLEEP for a machine you list in display.may sleep that went quiet during quiet hours , with vitals on the default board and the phone. A machine its owner declared RESERVED, under MAINTENANCE or DRAINING is shown calmly, with its reason and until when, and its silence is not an alarm. 4. The log: off course first: work that needs action failed, blocked, a call and work running long, nothing else. Then the rest, calmer: under way, waiting on a gate, a PR, a person, capacity or quiet hours, and until when, counted apart , no word, landed. Each row has a project chip, a plain title cut only at a whole word, one of six row words Waiting on you, Stuck, Can't tell, Working, Waiting on someone else, Finished and one sentence never a raw status line or a task id; the full text is inside the opened row; see docs/theme-spec.md https://github.com/Moshik21/weatherdeck/blob/main/docs/theme-spec.md section 9.5 and an honest percent range , or its phase "2 of 4" when the source knows the phase and not a percent; rows that do not fit fold into one "+N more" row. Its last row carries one chip per allowance account: provider, account, window, percent left and reset time, in a fixed order. 5. On the phone, below: waiting items, work under way, waiting, landed in the last 24 hours or since your day start , up next, releases, allowance, machine vitals, sources and the last 12 hours. 6. Click in. Every plate is a door to its place, and every row in a place opens in full: the calls each with the exact line to say in chat and a Copy button; the board never sends anything , the lanes with their steps and history, what is next, what landed, the machines with their stations and reporters, and the log of every push the host received. Each level is a URL /ship/<machine /deck/bridge , so Back, a shared link and a pinned TV work; a TV left on a deck or on the lists returns to the open sea after a minute. See docs/theme-spec.md https://github.com/Moshik21/weatherdeck/blob/main/docs/theme-spec.md section 16. Quiet hours with nothing waiting show a dim resting screen on the TV; a lost host shows a plate that counts down to the next try. Themes. The core is generic; each look is a folder under web/themes/ theme.name in the config . default is plain slate with system faces. ship-deck draws the fleet as a ship at sea in hi-bit pixel art machines are deck sections, work is the crew , with self-hosted OFL fonts. Each sailor stands at the station for its lane's stage, and a few creatures carry one piece of news each: a longboat for a landing, dolphins escorting the first one in ten minutes, gulls that leave a machine whose reporters go late, a whale for a release, slack sails for work gone quiet, and a lighthouse for the board's own host. Each is written to the Logbook. Opt-in sound off by default rings bells for a new call. See docs/theme-spec.md https://github.com/Moshik21/weatherdeck/blob/main/docs/theme-spec.md sections 16 and 17; weatherdeck run --demo --scenario sea-life plays every one in about three minutes. Preview any state without touching data: add controls=1 to the page URL and use the buttons late, stale, lost, host down, empty, loading, night, anchor, sky, motion, theme . night=1 forces the night palette, theme=ship-deck previews a theme. - Binds only the addresses you list; 0.0.0.0 and :: are refused. Default: localhost only. - No tokens: ingest from the local machine only. With tokens: per-source, and a token cannot speak for another source. - View profiles: full at / , a tv view at /tv/ for a screen the household can see task titles, repo names and pull-request links, no free text about what a worker is doing , and a redacted public view at /public/ counts, group and machine names, percent only . Each has its own optional read token, and each listen address chooses which profiles it serves, so a TV on the LAN can be given the tv view only. weatherdeck privacy on turns the tv view into counts only until weatherdeck privacy off . Redaction happens on the host, never only in the browser. - Feed text is untrusted: the page sets it with textContent , under a strict content security policy. bin/weatherdeck .cmd the command launchers for src/ src/weatherdeck/ server, ingest, merge, history store, demo player web/ the page: index.html, theme.js, frontdoor.js, model.js, board.js, decks.js, page.js, sightings.js, livery.js, weather.js, world.js, app.js, style.css; themes/ examples/ demo feeds, a generic adapter, an example host config docs/ spec and hosting guide scripts/ self-audit, release-scan, merged-check, build-package, build-static-demo, record-demo-feed source repo only MIT licensed, see LICENSE https://github.com/Moshik21/weatherdeck/blob/main/LICENSE .
