## 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? Telemetry feature. ## What is the current behavior? - Session replay is off, and nothing in the code keeps it off. - `packages/common/posthog-client.ts` sets no recording config at all. - So PostHog's project setting alone decides, for every app sharing that project. - Studio, www and docs share one project. - Studio shows customer data almost everywhere: SQL editor, table rows, connection strings, API keys. - posthog-js masks inputs by default. It does not mask rendered text. - [GROWTH-1055](https://linear.app/supabase/issue/GROWTH-1055) ## What is the new behavior? - `posthogClient.init()` takes a masking config, and disables recording when it gets none. - Studio passes one behind `NEXT_PUBLIC_POSTHOG_SESSION_REPLAY`. - Every other app passes nothing, so it never loads the recorder. - Studio masks all text and all inputs. - `data-ph-capture="true"` opts one element's text back in. Unused so far. - Canvas is blocked, because it records as images that text masking cannot reach. - Query strings and fragments are stripped from recorded URLs, where auth callbacks carry tokens. - Request and response bodies are never recorded. - Console logs are never recorded, since masking only reaches DOM text. - Masking is set in code, so PostHog's settings cannot loosen it. - Consent gating is unchanged. Nothing records before a user accepts. ## Additional context - Recording needs three things: this env var, the PostHog project toggle, and user consent. - All three are off or unset, so merging this changes nothing at runtime. - `NEXT_PUBLIC_POSTHOG_SESSION_REPLAY` goes into Vercel on Preview scope first, to test on a preview build. - Production scope comes later, once we are ready to record there. - `NEXT_PUBLIC_*` is inlined at build time, so each scope needs a rebuild afterwards. - Text inside HTML attributes (`title`, `alt`, `href`) is still recorded as-is. - posthog-js exposes no hook for masking attributes, so covering it needs `ph-no-capture` per component. - Staging has no server-side masking config, so that is where this gets verified. - Plan: enable recording on staging, verify masked text on a preview, then decide on production. - Network timing stays on for the dashboard performance work. Payloads stay off. - Tests cover both masking functions and the config values. ## Screenshots https://github.com/user-attachments/assets/aa064a04-f977-4453-a3da-2fe0cdcead08 <img width="889" height="651" alt="CleanShot 2026-07-31 at 10 13 43" src="https://github.com/user-attachments/assets/f1d07946-fd68-42b2-89f1-d201bc605638" /> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit ## Summary by CodeRabbit * **New Features** * Added privacy-focused session replay for Studio. * Text and form inputs are masked by default, with explicit opt-in capture. * Network recordings remove query strings and fragments. * Headers, request bodies, canvas data, and console logs are excluded. * **Bug Fixes** * Improved whitespace and capture-attribute handling during masking. * Session replay remains disabled without a masking policy or explicit enablement. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

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.
