The LLM-Independent Engineering Platform
nxtOS is an enterprise-grade, LLM-independent agentic development platform. A self-hosted, multi-agent runtime plans, builds, reviews, tests and documents software end to end — under your control, with the models you choose. It is built for engineering organisations that need repeatable delivery, full auditability and zero vendor lock-in.
Key Capabilities
Native Multi-Agent Runtime
Specialised agents — planner, project manager, coder, reviewer and librarian — coordinate the full delivery lifecycle with scoped permissions.
Any LLM, No Lock-In
First-class support for Anthropic, OpenAI, Gemini, local and custom providers, with per-agent routing, cost tracking and budget control.
Built-in PM & Workflows
An integrated project-management and operator UI with declarative, approval-gated workflows keeps delivery repeatable and governed.
Persistent Knowledge & Memory
A PostgreSQL/pgvector memory backend and a deterministic code-intelligence corpus retain architectural context across long-running projects.
Audit-Grade Traceability
Versioned task contracts, immutable message logs and streaming execution provide a complete, reviewable delivery history.
Self-Hosted, Two Ways
Run locally for a single engineer or on your own server for whole teams — your source code never leaves your infrastructure.
Built For Future-Oriented Organisations
Engineering Teams
Increase delivery throughput with AI while preserving discipline, quality gates and review.
Technical Founders
Move from idea to PRD to production-ready code and documentation in one governed workflow.
Enterprises & Integrators
Deliver repeatable, auditable engineering with explicit provider policy and no lock-in.
