Open-source lab

Open sourcefor enterprises.

Production-minded open-source products and reference architectures for business logic, telemetry ownership, controlled code execution, and data-contract drift.

PURISTA

Business logic first. Deployment shape second.

PURISTA is an open-source TypeScript stack for enterprise software architecture and implementation. It maps business capabilities into validated services, commands, subscriptions, and runtime adapters so teams can start simple and scale toward distributed or Kubernetes deployments when the organization is ready.

message flow PURISTA

Definition service builders schemas, commands, subscriptions

Implementation business logic validated command handlers

Runtime adapters bridge, stores, providers

deployment shape monolith -> services -> kubernetes

AI Harness

AI agents need an operating model before they touch enterprise workflows.

AI Harness is self-hosted TypeScript infrastructure for building provider-neutral LLM agent systems inside an application or platform, with typed agents, workflows, tools, skills, state, sandboxing, run events, traces, and eval helpers.

CloudGrid

Observability is not a place to rent your own production truth.

CloudGrid is an open-source, self-hosted OpenTelemetry observability platform that keeps traces, logs, metrics, dashboards, and AI-agent evaluation inside infrastructure the enterprise operates.

QuickJS Sandbox

Run code you did not write without pretending the host process is a sandbox.

QuickJS Sandbox gives TypeScript applications a controlled QuickJS WebAssembly guest runtime for user-provided, plugin, or AI-generated JavaScript and TypeScript, with explicit host capabilities and structured results.

SurrealDB Client Generator

Keep SurrealDB schemas, validation, and TypeScript clients in sync.

surql-gen reads SurrealDB schema definitions from a live database or .surql files and generates Zod schemas, TypeScript types, and optional client helpers while preserving customization points outside regenerated code.
