Every line auditable. Every module forkable. Every integration yours to own. Built for operators running tight margins who can't afford black-box vendor lock-in.
Assembling your stack
Six production-hardened modules. Each ships independently, integrates cleanly, and can be replaced without touching the rest.
Inventory Sync
CoreReal-time stock levels across all locations. Variance alerts fire before you run out, not after.
Webhooks push deltas every 200ms. Sub-second sync between 50+ locations.
Multi-Location
OperationsOne dashboard for every register. Drill from chain-wide P&L to a single line item in two clicks.
Supports up to 500 concurrent locations on a single tenant.
Offline Mode
ReliabilityInternet goes down. Register stays up. Transactions queue locally and sync the moment connectivity returns.
IndexedDB queue with conflict resolution. Zero lost transactions in 18 months of production.
Plugin Marketplace
ExtensibilityLoyalty programs, kitchen display systems, accounting exports — install in one command, fork and modify at will.
140+ community plugins. Build and publish yours with the Plugin SDK.
API-First Architecture
DeveloperEvery action in the UI is a documented API call. Build your own front-end, integrate your ERP, or automate anything.
REST + GraphQL. OpenAPI 3.1 spec ships with the repo.
Real-Time Analytics
IntelligenceRevenue per cover, hourly throughput, void rates by operator — live, not last night's batch job.
ClickHouse backend. Sub-second query on 100M+ transaction rows.
One command.
Six services.
Your entire POS stack — database, cache, analytics engine, message queue, API gateway — spins up in under 90 seconds on any Linux box.
Signal from production
We run 23 locations on Terminal. Switched from Toast 14 months ago — saved $94k in annual licensing fees and our IT team actually understands the codebase now.
Built a custom loyalty integration in a weekend using the Plugin SDK. With our old POS that would've been a 6-month vendor negotiation and a $40k quote.
White-labelled Terminal for a chain of 8 boutique hotels. Clients get a POS that looks like theirs, I own the code, and there's no licensing call when they want a new feature.
Deploy your
demo instance
We spin up a sandboxed Terminal instance pre-loaded with your industry's sample data. No credit card. No sales call. Just a working POS you can break, fork, and explore.
