Carlquist is the middleware layer between your legacy databases, ERPs, and vendor APIs — and the modern Node.js applications your team builds. Secure adapters, canonical schemas, and full observability. Ship in days, not quarters.
Enterprise middleware for legacy modernization
The Platform
Carlquist is not another API gateway. It's the translation layer that makes legacy systems speak modern — with enterprise guarantees baked in.
Legacy sources your business actually runs on — not just the shiny ones.
A modern, typed surface your frontend and partner teams can actually build against.
Enterprise promises that hold up in an audit, not just a slide deck.
How It Works
No six-month implementation. No consultants. Your first adapter ships today.
Point Carlquist at a legacy source. Schema detection and auth config are automatic.
carlquist connect
Map source fields to your canonical schema. Visual editor or code — your choice.
carlquist map
Publish a typed REST or GraphQL API with auth, rate limits, and versioning.
carlquist expose
Stream changes in real-time. Webhooks, Kafka, or polling — built-in dead letter handling.

Platform Capabilities
Role-based access, field-level masking, AES-256 at rest, TLS 1.3 in transit. Full audit logging. SOC 2 Type I in progress.
Structured logs, distributed traces, and per-adapter metrics. Correlation IDs propagated end-to-end.
Drag-and-drop mapping designer. No code for 80% of integrations. Git-backed version control.
One source of truth. Versioned schemas shared between adapters and consumers. JSON Schema + Zod.
Exponential backoff, dead-letter queues, idempotency keys, and backpressure controls. Legacy doesn't melt.
Deploy in US, EU, or APAC. Enforce data residency per adapter. Meet any compliance requirement.
