Activepieces

Activepieces, backed by Y Combinator, is an automation platform for building AI-powered workflows connecting 700+ business applications, trusted by MoneyGram, Red Bull, Rakuten, DocuSign, Roblox, and PostHog, with 300,000+ users. AI Agents provide intelligent automation with custom logic and integrations; a visual drag-and-drop Workflow Builder creates automations without code; 700+ integrations reach tools like HubSpot, Slack, OpenAI, Notion, and Salesforce; enterprise controls include SSO, SCIM provisioning, RBAC, and audit logging; deployment is available cloud-hosted or self-hosted (Docker, Helm); and Impact Analytics tracks adoption, hours saved, and cost savings. A free-forever plan requires no credit card, with execution-based pricing described as "$0 per execution — run millions, pay the same," a genuinely unusual, predictable cost structure. It's also open source under the MIT License. Good fit for a team that wants no-code automation across 700+ apps with predictable pricing that doesn't scale with execution volume, plus the option to self-host for full control.
