Inventory.
In any shape you need.
Open Stock Keeper is a shape-shifting inventory engine. Track every flight, every seat, every ancillary, every partner service — across any dimension you can describe. Time, geography, channel, partner, you name it.
In active build · early access available. Built on DocumentForge with smarts from RuleForge.
Coming SoonInventory, redefined
Most airline inventory systems were built around flight legs, then bolted on ancillaries, then bolted on partner products. Open Stock Keeper starts from first principles: anything you can count is a counter, on any dimension you can describe.
Built on the Open Order Database for sub-millisecond reads, with the Open Rules Engine powering conditional logic — eligibility, partner overrides, throttles — declaratively. Live numbers, audit trail, replay from any point in history.
Built on DocumentForge
Sub-millisecond decrements, append-only revision history, deterministic replay. The same engine that powers our Order Database.
Shape-shifting counters
Track anything: flights, cabins, seats, ancillaries, lounges, partner inventory. Slice over any dimension — time, geography, channel, partner.
Smarts via RuleForge
Conditional logic — partner overrides, fare-class throttles, eligibility — authored as visual rules. No procedural code rotting in microservices.
Chainable counters
Flight → cabin → seat → ancillary → partner service. One decrement cascades the dependency tree, in one transaction, with full audit.
Real-time + replayable
Live numbers for every consumer. Full audit trail for finance. Deterministic replay for ops. The same data, three views.
Partner-friendly
Partners can query and adjust counts via a clean public API. Capacity sharing, slot trading, codeshare reconciliation — built in.

We're scoping the first integrations now. If your airline has an inventory pain point that doesn't fit a flight-leg counter, we want to hear about it.
