What launched
Sim (built by Sim Studio, a Y Combinator company) shipped its third Product Hunt launch on July 10, 2026, for an open-source workspace that lets teams build, deploy, and orchestrate AI agents. Instead of hand-wiring API calls between a model and the tools it needs to act on, Sim gives builders a visual, Figma-like canvas: drag a block for an LLM, drag a block for Slack or Supabase or Gmail, and connect them into a working agent.
Why it matters
The AI agent space has gotten crowded with closed, hosted “agent builder” SaaS tools that lock workflows into a single vendor’s infrastructure. Sim’s pitch is the opposite: Apache 2.0 licensed, self-hostable, and SOC2 compliant for teams that need to keep agent workflows and the data flowing through them inside their own infrastructure. That combination — a genuinely open core plus enterprise-grade compliance — is unusual; most open-source agent frameworks require significant integration work to reach the same bar, and most compliant hosted platforms aren’t open source at all.
Who it’s for
- Founders and platform teams who want to prototype agent workflows quickly but don’t want to be re-architecting when they outgrow a hosted vendor’s limits.
- Regulated or security-conscious teams that need self-hosting or SOC2-level guarantees before they’ll let an agent touch production data.
- Developers already comfortable wiring together APIs, who want a canvas that speeds up the “connect the dots” part of building an agent rather than replacing their own code entirely.
The numbers behind the launch
Sim has accumulated 28.8K GitHub stars, raised a $7M Series A, and says it’s trusted by 100,000+ builders — traction that predates this specific launch but underscores that this isn’t a from-scratch product debut. It connects to 1,000+ integrations and LLMs, and is queryable/orchestratable from what the team calls a “unified visual canvas that bridges the gap between low-code layout and actual deployment.”
