Line icons are stroke-only by brand rule, but a partner's logo (Grafana,
Multigres, etc.) needs to render in ITS OWN colors — a second asset kind
alongside the existing icon system, not a replacement for it.
- supabase/migrations/0002_logo_assets.sql: add width/height to `assets`
(kind + storage_path already existed from 0001)
- lib/assets/sanitize-svg.ts: sanitizeLogoSvg() — a separate allowlist that
PRESERVES fill/stroke/gradients/style color declarations (unlike the icon
sanitizer, which strips them for the stroke-only treatment), while still
blocking scripts, event handlers, and external references (internal `#id`
refs are kept so gradient defs/<use> keep working). Unit-tested against a
mixed color+attack payload.
- lib/supabase/assets.ts: insertLogoAsset() uploads to the og-assets Storage
bucket (raster-safe, unlike inline SVG bodies) and records client-measured
width/height; rowToIcon exposes kind/url/width/height for both kinds.
- app/api/assets/route.ts: POST branches on a `kind` field ('icon', default,
or 'logo'); logo accepts SVG/PNG/JPEG/WebP up to 2MB, requires width+height.
- app/api/og/route.tsx: icon slots render logos as-is (no stroke
normalization), fit to their natural aspect ratio via a new fitBox() helper.
- app/page.tsx: a second "+ Upload logo (color)" control measures the file's
natural dimensions in-browser (Image().onload) before POSTing; the icon
picker renders logo entries as real <img> (actual colors) instead of the
forced-stroke SVG redraw.

Community & Support
- Community Forum. Best for: help with building, discussion about database best practices.
- GitHub Issues. Best for: bugs and errors you encounter using Supabase.
- Email Support. Best for: problems with your database or infrastructure.
- Discord. Best for: sharing your applications and hanging out with the community.
How it works
Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.
Architecture
Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.
- Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
- Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
- PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
- GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
- Storage a RESTful API for managing files in S3, with Postgres handling permissions.
- pg_graphql a PostgreSQL extension that exposes a GraphQL API.
- postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
- Kong is a cloud-native API gateway.
Client libraries
Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
