<!-- ccr-slack-attribution --> _Requested by **Lakshan Perera** · [Slack thread](https://supabase.slack.com/archives/C023E4L60R3/p1784055775538959?thread_ts=1784055775.538959&cid=C023E4L60R3)_ ## I have read the [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) file. YES ## What kind of change does this PR introduce? Docs update. ## What is the current behavior? Both the "Edge Function bundle size issues" troubleshooting page and the Edge Functions "Limits" page stated only a single **20 MB** limit. In practice, that 20 MB figure applies only to **local bundling** with the Supabase CLI. When a function is deployed via the **Management API or Dashboard**, bundling runs server-side and is capped at **5 MB** due to an infrastructure (Lambda) limit. Customers deploying that way were surprised to hit an error like `Function source code exceeds the maximum deployment size (5 MB). Reduce the size of your function and try again.` even though the docs implied 20 MB was available. ## What is the new behavior? Both pages now state the distinction explicitly: - **Local bundling (Supabase CLI):** up to **20 MB**. - **Server-side bundling (Management API or Dashboard):** up to **5 MB**. The troubleshooting page also adds a "Deploying larger functions" section pointing customers at the workaround: if a function is under 20 MB but over the 5 MB server-side limit, bundle it locally by running `supabase functions deploy` with the `--use-docker` flag to force local bundling and get the higher limit. ## Additional context **How / files changed:** - `apps/docs/content/troubleshooting/edge-function-bundle-size-issues.mdx` — rewrote the intro to describe both limits, added the "Deploying larger functions" workaround section, and fixed the frontmatter `keywords` (replaced `"10MB"` with `"5MB"` and `"20MB"`). - `apps/docs/content/guides/functions/limits.mdx` — updated the "Maximum Function Size" line to list both the 20 MB local and 5 MB server-side limits. Before, both pages said only 20 MB, so customers deploying via the API/Dashboard were surprised by a 5 MB error; after, both pages state the 5 MB server-side vs 20 MB local distinction and point to local bundling as the workaround. --- _Generated by [Claude Code](https://claude.ai/code/session_019bBXmQTRBWJbo3UTpfjPLU)_ Co-authored-by: Claude <noreply@anthropic.com>

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.
