Can Supabase Pro be vibe coded?
Self-host a Postgres backend with auth, storage, and a small API surface
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Supabase Pro, self-host a Postgres backend with auth, storage, and a small API surface. The hard boundary is managed postgres, backups, auth delivery, storage, edge functions, observability, and support, plus infrastructure scale, operations, and reliability.

The achievable core
- Self-host a containerized Postgres backend with auth, storage, and a small API surface, route domains, retain logs, and perform backups on one user-owned server.
- Build a focused single-user workflow with real persistence, search, and export.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- managed Postgres, backups, auth delivery, storage, edge functions, observability, and support
- global edge network
- managed databases
- autoscaling
- Reliability at the vendor's scale is an operations problem, not a prompt.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.
Why people still pay
People still pay for Supabase Pro because hosting products sell an operations team and failure-domain diversity, not merely a deploy button. The recurring cost buys patching, certificates, isolation, secrets, builds, deploys, logs, metrics, backups, capacity, incidents, and security response, not just the visible interface.
Reliability at the vendor's scale is an operations problem, not a prompt.

Build brief — a focused alternative to Supabase Pro
Context
**Supabase Pro** — Self-host a Postgres backend with auth, storage, and a small API surface. It currently costs Variable pricing.
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Supabase Pro, self-host a Postgres backend with auth, storage, and a small API surface. The hard boundary is managed postgres, backups, auth delivery, storage, edge functions, observability, and support, plus infrastructure scale, operations, and reliability.
This brief describes a focused, single-operator replacement for the part of Supabase Pro that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Self-host a containerized Postgres backend with auth, storage, and a small API surface, route domains, retain logs, and perform backups on one user-owned server.
Build a focused single-user workflow with real persistence, search, and export.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Linux server.
Docker.
Domain and DNS access.
Backup destination.
Basic systems administration.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a personal replacement for Supabase Pro in an empty repository.
Use Docker Compose, Caddy, PostgreSQL, Redis, and a small Go control plane; do not offer alternative stacks.
The core loop is: self-host a containerized Postgres backend with auth, storage, and a small API surface, route domains, retain logs, and perform backups on one user-owned server.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Accept a Git repository or container image and one explicit Dockerfile-based build path.
Implement applications, environments, secrets, domains, health checks, and rolling container replacement.
Use Caddy for automatic TLS and route only to healthy local containers.
Capture bounded build and runtime logs and expose restart, rollback, and redeploy actions.
Back up PostgreSQL metadata and document backups for each deployed application's data volumes.
Add host metrics, disk alerts, update instructions, disaster recovery, and a prominent single-server warning.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out multi-region or serverless infrastructure.
Deliberately leave out managed data stores and global edge delivery.
Deliberately leave out DDoS response, compliance, and guaranteed uptime.
Finish by running the tests and listing the exact commands used.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Managed Postgres, backups, auth delivery, storage, edge functions, observability, and support.
Global edge network.
Managed databases.
Autoscaling.
Reliability at the vendor's scale is an operations problem, not a prompt.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
What you still own after launch
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Risk
**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.
Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.
