A Backend for Chat & Messaging Apps on PostgreSQL
Messaging apps need durable, queryable history and solid access control. Kolaybase stores conversations and messages in PostgreSQL, authenticates users, and exposes message history over a REST API your client reads directly.
Durable message history
Persist every message in PostgreSQL with indexes for fast retrieval and pagination.
Per-conversation access
Row-level security ensures users only read conversations they're a participant in.
Simple REST integration
Load and send messages with plain HTTP from web or mobile, with filtering and ordering built in.
Scales with PostgreSQL
Handle growing message volume with Postgres indexing, partitioning, and concurrency.
Load a conversation's messages
const { data } = await kb
.from("messages")
.select("id, sender_id, body, sent_at")
.eq("conversation_id", conversationId)
.order("sent_at", { ascending: true });Frequently asked questions
- Can Kolaybase power a chat app?
- Yes for storage, auth, and history over REST. Live push (realtime subscriptions) is on the roadmap; today many apps poll or pair Kolaybase with a realtime transport for delivery.
- How do I keep conversations private?
- Use row-level security policies tied to conversation membership so the API only returns messages a user is allowed to see.
