Integrate Polar billing in server-side Python applications using the versioned Polar and PolarAsync clients. Use when implementing Polar customers and external IDs, checkout or customer portal sessions, customer-state entitlement checks, webhook validation and processing, API error handling, usage-event ingestion and metered billing, or migrating an application from the old Polar Python SDK.
Evidence-capture protocol for verifying web/dashboard/backoffice/checkout changes in the Polar local stack by driving the real UI with Playwright. Auto-discovered by the built-in /verify skill; can also be invoked directly. Brings up the Docker stack, logs in via the real email-OTP flow, and exercises flows end-to-end (including a live Stripe checkout) capturing screenshots as evidence.
Integrate Polar billing in server-side TypeScript applications using the versioned createPolar and createPolarCore clients. Use when implementing Polar customers and external IDs, checkout or customer portal sessions, customer-state entitlement checks, webhook validation and processing, API error handling, tree-shakable SDK calls, usage-event ingestion and metered billing, or migrating an application from the old Polar TypeScript SDK.

Helps manage the Polar local development environment through the dev docker
CLI. Use it to start, stop, debug, or reason about the local stack.
dev docker deliberately splits the stack so many worktrees can share one set
of heavy infra:
polar-shared:
postgres, redis, minio, tinybird, and optional prometheus/grafana. Postgres
and redis publish no host ports; MinIO exposes 9000/9001 for browser
uploads. Use dev docker exec <service> ... for services without host ports.polar-app-<N>: api,
worker, web. Only api and web publish host ports, offset per instance so
worktrees don't collide.Knowing this prevents the most common confusion: there is no localhost:5432
for the database (it lives in the shared stack and is reached through
dev docker exec db ...). MinIO does expose ports 9000/9001 for browser
uploads and console access.
dev docker auto-detects the instance for the current worktree, so -i is
rarely needed. Priority:
POLAR_DOCKER_INSTANCE pinned in dev/docker/.env.docker (dev docker set-instance N)CONDUCTOR_PORT env var → (port - 55000) / 10 + 1~/.config/polar/docker-instances.json)Run dev docker ports to see the resolved instance and its URLs (add --json
for tooling). To wire this worktree into Claude Code's preview, run
dev docker launch-json, which writes a per-instance .claude/launch.json with
the correct ports (it's gitignored, so regenerate after set-instance).
| Task | Command |
|---|---|
| Start full stack (background) | dev docker up -d |
| Start and block until healthy | dev docker up -d --wait |
| Start in foreground (stream logs) | dev docker up --no-detach |
| Rebuild with fresh base images | dev docker up -b --pull -d |
| Show this instance's ports/URLs | dev docker ports (--json for tooling) |
| Write Claude Code preview config | dev docker launch-json |
| Stop app stack | dev docker down |
| Stop app and shared infra | dev docker down --all |
| Follow logs | dev docker logs -f [service] |
| Print logs and exit | dev docker logs --no-follow [service] |
| Status | dev docker ps |
| Restart a service | dev docker restart <service> |
| Shell into a service | dev docker shell <service> |
| One-off command in a service | dev docker exec <service> <cmd> |
| Reset this instance | dev docker cleanup -f |
| Wipe ALL shared data | dev docker cleanup --all -f |
| List every instance | dev docker list |
| With monitoring | dev docker up --monitoring -d |
| Service | Project | Host port (instance 0 / N) | Notes |
|---|---|---|---|
| api | polar-app-<N> | 8000 / 8100+N | FastAPI; /healthz healthcheck |
| web | polar-app-<N> | 3000 / 3100+N | Next.js; healthchecked |
| worker | polar-app-<N> | none | Background jobs |
| db | polar-shared | none (exec) | PostgreSQL; DB polar_dev_<N> |
| redis | polar-shared | none (exec) | Redis DB index = N |
| minio | polar-shared | 9000, 9001 | S3; buckets polar-s3-<N>; console at 9001 |
| tinybird | polar-shared | none (exec) | Analytics |
| prometheus / grafana | polar-shared | none (exec) | --monitoring only |
Discover the exact host ports for the current worktree with dev docker ports.
Only api and web get host ports: Port = Base + Instance (Base 8100 for api,
3100 for web) for instances 1–99. Instance 0 uses the legacy 8000 / 3000.
| Instance | API | Web |
|---|---|---|
| 0 | 8000 | 3000 |
| 1 | 8101 | 3101 |
| 2 | 8102 | 3102 |
| 5 | 8105 | 3105 |
Everything else is per-instance but not on a host port: database polar_dev_<N>,
redis DB index <N>, buckets polar-s3-<N> / polar-s3-public-<N>. Reach them
via dev docker exec <service> or docker exec polar-shared-<service>-1.
