<!-- ccr-slack-attribution --> _Requested by **Pam Chia** · [Slack thread](https://supabase.slack.com/archives/C076KTY11DF/p1789979683276099?thread_ts=1789953317.522459&cid=C076KTY11DF)_ ## 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? Bug fix. ## What is the current behavior? **Before:** `copyToClipboard` writes text with `navigator.clipboard?.writeText(text)`. When `navigator.clipboard` is undefined — an insecure context, such as self-hosted Studio served over plain http or Studio reached over a LAN IP, where `ClipboardItem` is also undefined so the Safari branch above is skipped — the optional chaining makes the whole expression resolve to `undefined`. Nothing throws, so the `catch` never runs and the success callback on the next line runs anyway. The caller is told the copy succeeded: the UI shows its "Copied!" confirmation state and the copy-tracking telemetry event fires as a successful copy, even though nothing reached the clipboard. That contradicts the documented contract of those events, which are defined as firing only when the clipboard write succeeded. ## What is the new behavior? **After:** the missing-clipboard case fails instead of silently succeeding. The callback does not run, no copy event fires, and the error toast that the function already shows on failure (`Unable to copy to clipboard`) is what the user sees. Every working path behaves exactly as before, including the Safari `ClipboardItem` branch, which is untouched. ## Additional context How: throw when `navigator.clipboard` is missing, inside the `try` block that already exists, so the case lands in the existing `catch` and its error toast rather than falling through to the success path. The now-redundant optional chaining on the write is dropped. One case was added to the existing shared clipboard util tests asserting that the callback does not fire and the error toast shows when the Clipboard API is unavailable; it fails on `master` and passes with this change.

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.
- Envoy is a cloud-native, high-performance edge and service proxy.
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.
