Filling a bed left the outer row too far from the edge, and staggered rows worse still. Two defects, both from anchoring the lattice at the region's min corner: - Odd rows offset by `radius` started at `MinX + 2·radius`, leaving a bare strip a whole plop wide down one side of every other row. - All the leftover slack piled up on the far edge, where plops hung 13cm outside the bed on a 4×8ft garlic bed. Nothing clips them, so they drew over the bed outline. Spacing is a constraint between neighbouring plants competing for the same soil, light and water. A bed edge is not a competitor, so the outer row owes it half the spacing — the arithmetic inside every square-foot-gardening chart (4/square = 6" apart, 3" from the square's edge). The wrinkle: a plop is a CLUMP, not a plant. defaultPlopRadius is 1.5×spacing, so keeping the whole circle inside the bed insets the outer row by 1.5 spacings, three times what the rule allows. So centre the lattice and set the minimum centre-inset to `radius - spacing/2`: the clump may cross the edge by up to half a spacing, putting its outermost plants exactly the half-spacing from the edge the rule asks for. Capped there — a clump mostly outside the bed would be a drawing of plants in the path. Same bed, same 15 plops, now symmetric with a deliberate 6.5cm overhang inside the 7.5cm budget instead of an accidental 13cm on one side only. The stagger falls out of the centring for free: an offset row holds one fewer plop, and centring that run puts it exactly half a pitch off its neighbours. TestFillRegionDeterministicPacking expected 4 plops in a 60×60 bed; the fourth was centred ON the east edge with half of it outside, well past the budget. It is 3 now — the fix working, not a regression in it. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> Claude-Session: https://claude.ai/code/session_01H3zbym8Doka2d7D48maSgZ
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 disabled, not broken — the chat routes simply aren't registered. |
PANSY_AGENT_MODEL |
ollama-cloud/glm-5.2:cloud |
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. |
PANSY_AGENT_ENABLED |
on when a key is present | Turns the assistant off without removing the key. |
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 garden assistant disabled at startup with which of the three conditions failed, so the answer is in the first few lines of the log.
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:
