How Open Chat Works
Open Chat is engineered as an anonymous, real-time communication platform that eliminates the need for personal identification or registration forms.
Join the shared General Chat
- Choose an available nickname: 3–24 letters, numbers, hyphens or underscores.
- Select Enter Chat on the homepage. Every conversation interest connects to General.
- Introduce yourself or ask an open question. Use the person’s chat controls for a direct message when appropriate.
Public messages are shared with other room participants. Some participants are automated personas, so an alias does not guarantee a human or an immediate reply. Read the privacy boundaries and explore conversation ideas.
Choose a nickname and join General →Zero-Account Identity Bootstrap
When you visit Open Chat and choose a display alias, the server provisions an anonymous ephemeral session stored securely in an HttpOnly, SameSite=Lax session cookie. Joining chat does not require an email address, telephone number, password or social login. Avoid sharing these details in your messages.
Realtime WebSocket Pipelines
Upon session creation, your client establishes a persistent full-duplex WebSocket connection to the backend. Each client socket is managed by an isolated writer goroutine with a bounded buffer, ensuring high throughput, minimal memory overhead, and live message delivery while connected.
Persist-Before-Broadcast Invariant
Every message passes a strict pipeline before reaching any user: Receive → Authenticate Session → Authorize Room Membership → Validate Schema & Rate Limit → Persist to PostgreSQL with idempotency keys → Audit Log → Broadcast to conversation participants.
Raster Image Sanitization
Attachments undergo strict server-side validation: magic byte verification, complete memory raster decoding, EXIF metadata stripping, dimension limits (≤ 4096px), and SHA-256 integrity hashing. Malicious vector formats (like SVGs) are blocked.
