Prerequisite for seed-packet capture (#81). majordomo's media pipeline is stdlib-based and cannot decode HEIC or webp — and HEIC is the iPhone camera default, so the capture feature's very first input would fail on the device that motivates it. Normalizing at the upload boundary means everything downstream only ever sees JPEG. internal/imagenorm.Normalize(reader, opts) decodes any of jpeg/png/heic/webp, downscales to fit MaxDim (2048, ollama-cloud's limit) on the longest edge with Catmull-Rom (sharp on the text a packet is mostly made of), and re-encodes JPEG. CGO stays off: github.com/gen2brain/heic runs libheif as WASM via wazero (pure Go), golang.org/x/image/webp is pure Go. Both register with image.Decode. The ~5 MB these add only links into the binary when #81 imports this package — it's not pulled into cmd/pansy yet, so main is unchanged in size for now. Guards against hostile uploads: input capped at MaxBytes (ErrTooLarge) before a full read, and the decoded pixel count checked from DecodeConfig BEFORE the bitmap is allocated, so a small file claiming a huge canvas (a decompression bomb) is refused up front. TestNormalizeAllFormats round-trips all four formats to a valid JPEG — its real job is catching a dropped blank import, where the intuition-breaking failure is that the COMMON format (png) breaks while the exotic one (heic) still works. heic/webp fixtures live in testdata (Go has no encoder for them); the webp is a known-good 16x16 from Python's stdlib test corpus, verified to decode.

pansy
Self-hostable garden planner: drag beds, bags, and containers onto a real-scale field, click into them to place freeform plops of plants, and zoom out to see what's planted where. Go backend + React frontend, one static binary.
🤖 This is a vibe-coded project
Essentially all of the code in pansy was written by an LLM (Claude), with a human directing the work, reviewing it, and deciding what ships. Every pull request also gets an automated adversarial review before it lands.
That's said up front because you deserve to know it before you trust pansy with anything: it hasn't been through the kind of scrutiny a hand-written, widely-used project has. Read the code before you self-host it. Back up your database. Bugs here are the ordinary kind of bugs, not a scandal — but so is the fact that nobody hand-wrote the thing.
See DESIGN.md for the architecture. Work is tracked in this repo's issues — start from the tracking epic.
Quickstart
Prerequisites: Go 1.26+, Node 20+.
Develop
Run the Go API and the Vite dev server together (Vite proxies /api → the API):
make dev
Then open http://localhost:5173. Or run the two halves in separate terminals for independent restarts:
make dev-api # Go API on :8080
make dev-web # Vite dev server on :5173
Build & run
Produce the single static binary with the web build embedded, then run it:
make build
./pansy
Open http://localhost:8080 — one process serves both the JSON API and the app.
Test
make test
Configuration
All configuration is via environment variables; every value has a default, so ./pansy runs with none set.
| Variable | Default | Description |
|---|---|---|
PANSY_PORT |
8080 |
TCP port the HTTP server listens on. |
PANSY_DB |
./pansy.db |
SQLite database file path (created if absent). |
PANSY_BASE_URL |
(empty) | Externally-visible base URL; used to derive the OIDC redirect URI. |
PANSY_REGISTRATION |
open |
open or closed — gates local self-service signup. |
PANSY_LOCAL_AUTH |
true |
Enable local password auth. Set false for pure-OIDC. |
PANSY_OIDC_ISSUER |
(empty) | OIDC issuer/discovery URL (Authentik). Enables SSO when set. |
PANSY_OIDC_CLIENT_ID |
(empty) | OIDC client ID. |
PANSY_OIDC_CLIENT_SECRET |
(empty) | OIDC client secret. |
PANSY_OIDC_BUTTON_LABEL |
Sign in with Authentik |
Label for the OIDC button on the login page. |
PANSY_TRUSTED_PROXIES |
(none) | Comma-separated proxy CIDRs/IPs to trust for client-IP resolution. |
The garden assistant reads three more. Setting none of them leaves the assistant off; the app runs exactly as it does without it.
| Variable | Default | Description |
|---|---|---|
OLLAMA_CLOUD_API_KEY |
(empty) | Ollama Cloud API key. Without it the assistant is off, not broken. This is the one agent value that stays in the environment — it is never stored in the database or editable in Settings. |
PANSY_AGENT_MODEL |
ollama-cloud/glm-5.2:cloud |
Default model spec, passed verbatim to majordomo.Parse — a comma-separated list is a failover chain, e.g. ollama-cloud/glm-5.2:cloud,ollama-cloud/kimi-k2.6:cloud. An admin can override this per-instance in Settings without a redeploy; a blank Settings value inherits this. |
PANSY_AGENT_ENABLED |
on when a key is present | Default on/off for the assistant. Also overridable in Settings (which can inherit this default). |
The model and enabled flag can be changed at runtime by an admin under Settings (the gear appears in the nav for admins) — the change swaps the live assistant with no restart. The env vars above are the defaults an untouched instance uses, and the API key is intentionally not among the runtime-editable settings: a secret in the database would land in every backup. Precedence for the model and enabled flag is Settings value, if set → env var → built-in default.
The assistant acts without asking first, which is only reasonable because every turn is one undoable change set — see the History panel in the editor.
If you set the key and the assistant still doesn't appear, check that the variable reaches the container, not just your orchestrator's stack config — Compose needs it listed under the service's environment:. pansy logs why the assistant is off at startup, and Settings shows the same status (a key present, the resolved model, and whether it's actually running).
Local email/password auth is live (POST /api/v1/auth/register, /auth/login, /auth/logout, GET /auth/me, GET /auth/providers); the session is an HttpOnly cookie (Secure when PANSY_BASE_URL is https). The first account registered becomes admin, and it may register even when PANSY_REGISTRATION=closed to bootstrap the instance.
OIDC (Authentik-first) is live too: set PANSY_OIDC_ISSUER, PANSY_OIDC_CLIENT_ID, PANSY_OIDC_CLIENT_SECRET, and PANSY_BASE_URL (needed for the redirect URI). Register PANSY_BASE_URL + /api/v1/auth/oidc/callback as the redirect URI in your IdP. GET /auth/oidc/login starts an authorization-code + PKCE flow; first login provisions a user just-in-time (a matching verified email links to an existing local account instead of duplicating it). Provider discovery is lazy, so a briefly-unreachable IdP never blocks startup or local auth. Set PANSY_LOCAL_AUTH=false for pure-Authentik deployments (local register/login are then rejected and hidden from /auth/providers).
Docker & deployment
CI (.gitea/workflows/build-image.yml) builds the single-binary image and pushes it to the Gitea registry on every branch push:
| Ref | Tag |
|---|---|
main |
gitea.stevedudenhoeffer.com/steve/pansy:latest |
| any other branch | gitea.stevedudenhoeffer.com/steve/pansy:<branch-name> |
| every build | gitea.stevedudenhoeffer.com/steve/pansy:sha-<short> (immutable; use to pin) |
The image runs as a non-root user, serves on :8080, and stores the SQLite database on the /data volume. Run it directly:
docker run -d --name pansy \
-p 8080:8080 \
-v pansy-data:/data \
gitea.stevedudenhoeffer.com/steve/pansy:latest
Or as a Komodo/Compose stack:
services:
pansy:

- "8080:8080"

Pin PANSY_TAG to a sha-<short> tag for reproducible deploys, or leave it at latest to track main.
