Clobber is a hosted central limit order book. Create markets with a POST, accept orders in microseconds, stream fills over WebSocket. No exchange team required.
Everything a venue needs: markets, accounts, orders, settlement. Deterministic matching, price-time priority, an internal ledger that always balances.
Binary outcomes, currency pairs, or anything with a price. Tick size, fees and limits are yours to set.
Limit, market, IOC, FOK. Idempotency keys built in, acks in under a millisecond.
Book deltas, trades and fills per account, sequenced so you never miss an event.
Declare the result and every position settles atomically against the internal ledger.

Anywhere users should trade against each other instead of against a house price.
Launch a CLOB-based prediction market in days. Binary contracts, probability pricing, atomic settlement on resolution.
Let your audience predict with points or credits. Price discovery is the engagement loop; no real money, no licensing.
Game items, GPU hours, tickets, carbon credits. Replace fixed prices with a continuous double auction.
Self-serve with a card. No sales calls unless you want one.
A deterministic engine, every command journaled, replicas replaying the same log. Failover is a replay, not a fire drill. A public status page is on the way.
