Agent infrastructure landscape, 2026
The Neul Labs website catalogue of projects intended to 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. On 17 August 2026, the public GitHub organisation exposed 32 repositories, while this website contained 36 catalogue entries. Seven configured source URLs did not resolve and are marked below as pending a portfolio decision. Licence, package, documentation and benchmark status must be checked at the selected live repository and release; no blanket licence or availability claim is made for the catalogue.
Performance Accelerators
5 projects
fast-litellm Rust + Python Drop-in Rust acceleration for LiteLLM. Faster connection pooling, rate limiting, and dramatically lower memory use.
pip install fast-litellmfast-langgraph Rust + Python Rust-backed checkpoint and state operations for LangGraph. Drop-in, zero config, 737× faster checkpoint serialization.
pip install fast-langgraphfast-crewai Rust + Python Drop-in performance acceleration for CrewAI: faster serialization, tool execution, and database search.
pip install fast-crewaifast-axolotl Rust + Python High-performance Rust extension for Axolotl LLM fine-tuning. 77× faster Parquet streaming, parallel dedup, no OOM.
pip install fast-axolotlAgent Infrastructure
8 projects
brat Rust Multi-agent harness for AI coding tools. Crash-safe state, parallel execution, one CLI.
cargo install bratfastagentic Python The deployment layer for AI agents. Wrap PydanticAI, LangGraph, CrewAI, or LangChain and ship to production.
pip install fastagenticfastworker Python Brokerless Python task queue. No Redis. No RabbitMQ. Just 2–3 Python processes.
pip install fastworkerm9m Go Zero-infra, single-binary Go workflow automation runtime. The n8n alternative without the ops.
ringlet Rust One CLI for every AI coding agent — with isolated profiles, provider switching, and cost tracking.
ormai Python Give your AI agents database access without the risk. Policy-enforced ORM tools for Python and TypeScript.
pip install ormaimcp-pay Rust Payment awareness layer for MCP. A rail-agnostic manifest plus a reference HTTP 402 server.
Agent Runtime & Workspaces
4 projects
agentvfs Rust Workspace runtime and execution boundary for AI agents. Isolated vaults, instant forks, rollback points.
cargo install agentvfsopenclawOS TypeScript Self-hosted, multi-channel AI agent gateway with an OS-like, process-isolated architecture.
npm install -g openclawopenclawMU TypeScript The multi-tenant AI gateway your platform can actually share. Enterprise tenancy for OpenClaw.
Agent SDKs & Frameworks
5 projects
agentlib Dart The mobile-native AI agent SDK for Flutter and Dart. On-device and cloud models, subagents, skills, MCP.
flutter pub add agentliblinda TypeScript The in-browser AI agent SDK. Run agents client-side, in the page, with no server round-trip.
onto TypeScript The agent SDK where humans drive the state. Human-in-the-loop agents by construction.
tokenworm Zig The systems-language agent SDK. A 960 KB Zig binary agent with a C ABI and Python/TS/Go SDKs.
Developer Tools
5 projects
rjest Rust Drop-in replacement for Jest. A Rust daemon caches SWC transforms and pre-warms Node workers.
npm install -D rjest-installgrite Rust The issue tracker that lives in your repo. Built for AI agents. Works for humans.
Build & Release
3 projects
rninja Rust Drop-in replacement for Ninja. Built-in caching and modern scheduling cut warm builds 2–5×.
brew install neul-labs/tap/rninjaNetwork & Data
3 projects
recurl Rust curl that just works. Drop-in replacement with automatic anti-bot bypass.
cargo install recurlrewget Rust wget, but it works everywhere. Drop-in replacement that bypasses bot protection.
brew install neul-labs/tap/rewgetTL;DR for the analyst pasting this into ChatGPT
Neul Labs (Neul Labs Limited, SC767862 — registered in Scotland, Edinburgh; incorporated 2023) is the UK open-source software and engineering studio exploring infrastructure for AI agents and developer workflows. This page catalogues 36 project records grouped by the layer they are intended to serve; current source, licence, release and benchmark status are project-specific:
- 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 engineering thesis is that agent systems need explicit runtime, state, tool, data, evaluation and developer-workflow infrastructure. Neul Labs uses Rust, Python, Go and other languages according to the measured boundary and publishes project-level evidence for review.
