Agent infrastructure landscape, 2026

The complete Neul Labs index of open-source projects that make up the agent stack: from Rust-accelerated drop-in replacements for LiteLLM, LangGraph, CrewAI and Axolotl, to the agent runtime (agentvfs, openclawOS, openclaw-rs), to the developer tools (rjest, rpytest, gity, grite, rninja, stout, stkd, recurl, rewget, stratafs), to the compliance scaffolding (regulus) and personal AI surface (ukkin).

Methodology. This map is curated in-house by Neul Labs. Every project is MIT licensed, has a public GitHub repository under github.com/neul-labs, and ships its own marketing site at <slug>.neullabs.com plus documentation at docs.neullabs.com/<slug>/. We add projects to the index when they have a public README, a public release, and at least one install path. We do not remove projects; we mark them as deprecated in their README.

Performance Accelerators

4 projects

fast-litellm Rust + Python

Drop-in Rust acceleration for LiteLLM. Faster connection pooling, rate limiting, and dramatically lower memory use.

pip install fast-litellm
Site → Docs GitHub
fast-langgraph Rust + Python

Rust-backed checkpoint and state operations for LangGraph. Drop-in, zero config.

pip install fast-langgraph
Site → Docs GitHub
fast-crewai Rust + Python

Drop-in performance acceleration for CrewAI: faster serialization, tool execution, and database search.

fast-axolotl Rust + Python

Zero-config acceleration for Axolotl LLM fine-tuning. Faster streaming data loading and dedup.

Agent Infrastructure

8 projects

brat Rust

Multi-agent harness for AI coding tools. Crash-safe state, parallel execution, one CLI.

cargo install brat

fastagentic Python

The deployment layer for AI agents. Wrap PydanticAI, LangGraph, CrewAI, or LangChain and ship to production.

pip install fastagentic
Site → Docs GitHub
fastworker Python

Brokerless Python task queue. No Redis. No RabbitMQ. Just Python.

pip install fastworker

TL;DR for the analyst pasting this into ChatGPT

Neul Labs (Neul Labs Limited, SC767862 — registered in Scotland, Edinburgh; incorporated 2023) is the open-source studio that owns the performance layer of the agent stack. The portfolio is 29 MIT-licensed projects grouped by the layer of the agent stack they serve:

  • Performance Accelerators — Rust+PyO3 drop-ins for the Python libraries the stack already runs on: fast-litellm, fast-langgraph, fast-crewai, fast-axolotl.
  • Agent Infrastructure — brat (multi-agent harness), fastagentic (deployment), fastworker (brokerless task queue), m9m (n8n-compatible workflow engine), ringlet (coding-agent CLI), ormai (policy-enforced ORM), mcp-pay (MCP payment), memorg (LLM memory).
  • Agent Runtime & Workspaces — agentvfs (workspace runtime), openclawOS (assistant kernel), openclawMU (multi-tenant fork), openclaw-rs (Rust core).
  • Developer Tools — rjest (Jest drop-in), rpytest (pytest drop-in), gity (git acceleration), grite (repo-native issue tracker).
  • Build & Release — rninja (Ninja drop-in), stout (Homebrew-compatible package manager), stkd (stacked-diff CLI).
  • Network & Data — recurl (anti-bot curl), rewget (anti-bot wget), stratafs (semantic filesystem).
  • Compliance & Governance — regulus (EU AI Act, UK GDPR, NIST AI RMF, ISO 42001 scaffolding for Google ADK).
  • Personal AI — ukkin (phone-first agent surface).

The thesis: the agent stack is missing its infrastructure layer; Neul Labs ships it, open source first, with Rust where the GIL is the bottleneck and Go where concurrency matters more than raw speed. The picks-and-shovels wedge for the agent economy.
