Curator's take

The n8n-for-agents play at real scale (29k stars): build agents visually, conversationally, or in code, wire them to Slack/Notion/Salesforce-class integrations, and keep tables, files, knowledge bases and scheduled runs in the same workspace — it's a platform, not a library. Self-hosting is honest but heavy: Docker with 12GB+ RAM recommended, Postgres + pgvector, and note that the Chat/copilot feature remains a Sim-managed service even self-hosted (you fetch a COPILOT_API_KEY from sim.ai). Ollama/vLLM local models supported. Pick it when non-engineers need to build and operate agents; pick a code-first control plane (agentfield) when engineers do, and skip the platform entirely for a single agent.

README.md

A workspace to build, deploy and manage AI agents and workflows.

Quickstart

Cloud-hosted: sim.ai

Self-hosted

npx simstudio

Open http://localhost:3000

Docker must be installed and running. Use -p, --port <port> to run Sim on a different port, or --no-pull to skip pulling the latest Docker images.

The Sim platform — chat on the left, the visual workflow builder on the right

Capabilities

Connect 1,000+ integrations and every major LLM
Add Slack, Notion, HubSpot, Salesforce, databases, and more
Build agents visually, conversationally, or with code
Ingest files, knowledge bases, and structured table data
Monitor runs, logs, schedules, and workflow activity

One workspace, every surface

Chat and workflows are just the start — tables, files, knowledge, and scheduled tasks all live in the same workspace.

bytechef

Open-source platform unifying AI agent orchestration with classic workflow automation — visual builder, 200+ integration components, self-hosted via Docker. Apache 2.0 + EE split.

Why it fitsBoth are open, self-hostable platforms unifying AI-agent orchestration with classic workflow automation behind a visual builder and big integration catalogs — Sim leans agent-first with knowledge/tables/files built in; ByteChef leans integration-first with its 200+ components.

agentfield

Open-source control plane that runs AI agents as microservices: write plain Python/Go/TS functions, get REST endpoints with routing, queues, retries, memory and tracing — one laptop to 10k agents.

Why it fitsSame 'run your AI workforce' ambition, opposite audiences: AgentField turns plain Python/Go/TS functions into agent microservices for engineers; Sim gives teams a visual workspace where agents are built and operated without touching the runtime.
