Loopstack AI provides an open‑source NestJS‑based framework that lets developers define AI‑driven workflows with declarative YAML while implementing custom logic in TypeScript. The platform orchestrates stateful, long‑running agentic loops, offers human‑in‑the‑loop checkpoints, and records each transition for auditability via a web UI, CLI and SDK. Pre‑built templates and a community registry accelerate development without vendor lock‑in.

Problem
Developers and enterprises must stitch together multiple AI services, custom code, and orchestration logic to build AI‑driven applications. Existing solutions often require extensive boilerplate, lack a unified way to define long‑running, stateful workflows, and provide limited visibility for compliance or debugging.
Solution
Loopstack AI delivers an open‑source automation framework built on NestJS that lets teams define AI workflows with declarative YAML schemas while writing custom logic in TypeScript. The platform orchestrates agentic loops, supports persistent state and human‑in‑the‑loop checkpoints, and records every transition in version‑controlled YAML for auditability. Loopstack Studio offers a web UI to monitor, pause, and resume executions, and the CLI and SDK enable seamless integration into existing codebases or CI pipelines. Pre‑built templates and a community registry accelerate development without sacrificing control or compliance.
Target Audience
Primary users are software engineers and AI product teams building custom AI applications, as well as enterprise automation groups that require auditable, long‑running AI workflows with human oversight.
Features
- Hybrid architecture: NestJS services for custom AI logic combined with YAML‑based workflow definitions.
- Structured agentic orchestration: safe execution paths for autonomous AI loops with built‑in governance.
- Stateful long‑running workflows: automatic state persistence, human‑approval checkpoints, and resumable runs lasting days or weeks.
- Visual auditability: version‑controlled YAML and Loopstack Studio UI provide real‑time execution graphs and change history.
- Open‑source BSL license: full self‑hosting, no vendor lock‑in, and unrestricted customization.
- CLI and Registry: one‑command installation of community‑contributed modules, tools, and workflow templates.
- API/SDK and RunService: programmatic triggering of workflows from NestJS controllers, webhooks, or scheduled jobs.
- Extensible block model: workspaces, workflows, tools, and documents can be extended with TypeScript decorators for seamless integration.
