Zenbu
An extensible IDE for orchestrating coding agents, built on the minimal Pi agent. Around it, everything — including agent-management tools — is a plugin, so teams build their own workflow for running agents in parallel, reviewing AI-written changes and tracking the codebase.

Our take
An extensible IDE for running and orchestrating coding agents, built on the minimal Pi agent. Everything is a plugin — including the tools for managing agents — so teams shape their own workflow for running agents in parallel, reviewing changes nobody typed, and tracking the codebase. YC 2026; founder ex-Vercel/Next.js.
Best for
Developers running multiple coding agents who want to customize how they manage and review them.
Pros
- Built for orchestrating parallel agents
- Plugin-extensible, no fixed workflow
- Reviews AI-written changes in one place
- Founder with deep dev-tools pedigree
Cons
- Very new, small ecosystem
- Plugin model means assembly required
- Best once you already use agents heavily
How it compares
Where Cursor and Windsurf bake in one agent workflow, Zenbu leaves it open — the IDE itself is plugins, so teams build their own.
Full review
Zenbu is an extensible IDE for orchestrating coding agents. As agents take on more of the work, they create new complexity: running several in parallel, reviewing changes nobody wrote by hand, verifying their output and keeping track of the codebase. Zenbu is built to manage exactly that.
It sits on top of Pi, a minimal customizable coding agent, and makes everything a plugin — including the tools for managing agents — so teams can build the workflow that fits them rather than adopt one fixed approach. It is part of Y Combinator's 2026 cohort; the founder was on the Next.js core team at Vercel and co-authored React Scan.

Composio
Composio provides the execution infrastructure that connects AI agents to real software. It sits at the tooling and connectivity layer of the agent stack, giving developers one framework - SDKs, a CLI and 850+ pre-built connectors - to let agents act across apps such as GitHub, Slack and Salesforce. It handles the hard parts: complex authentication and OAuth, plus remote sandboxed environments for safe execution, exposed over the Model Context Protocol so agents can reason and then reliably take action. The platform is built for production, with SOC 2 and ISO 27001:2022 certifications and deployment across public cloud, VPC and on-premises. Composio operates from San Francisco and Bangalore and raised a $25M Series A led by Lightspeed, with angels including Vercel's Guillermo Rauch and HubSpot's Dharmesh Shah.
LiteLLM
LiteLLM, from BerriAI, is an open-source AI gateway that gives you a single OpenAI-compatible interface to 140+ providers and 2,500+ models, including OpenAI, Anthropic, Gemini, Bedrock, Azure, Mistral, Ollama and vLLM. You can use it as a lightweight Python SDK for direct calls, or deploy the proxy server as a centralized gateway for a team, with virtual keys, budgets, load balancing, rate limiting, request logging and LLM guardrails. It has become a default building block in the AI stack, with 45,000+ GitHub stars, 240M+ Docker pulls and over a billion requests served, and is used by companies including Netflix, Adobe and Stripe. The core is free; an enterprise tier adds JWT auth, SSO/SAML, audit logs, SLAs and dedicated support.
Claude Code
Terminal-based agentic coding tool from Anthropic for autonomous multi-step coding tasks.
Kiro
AWS agentic IDE built around spec-driven development: it writes a spec, then builds matching code, tests and docs across IDE, CLI and web.
