2B.AI

🟢No Code

AI-powered Chrome extension that automates task creation from any web content through drag-and-drop capture, intelligent intent recognition, and Google Calendar synchronization to improve daily productivity workflows.

Agent Cloud

🔴Developer

Open-source platform for building private AI apps with RAG pipelines, multi-agent automation, and 260+ data source integrations — fully self-hosted for complete data sovereignty.

Agent Cloud follows an open-core freemium model. The self-hosted community edition is completely free under AGPL 3.0 — the only costs are your own infrastructure (typically $50–$300/month on cloud VMs) and any LLM API fees (e.g., OpenAI at ~$0.01–$0.03 per 1K tokens). For teams that want a hosted experience, the Managed Cloud tier offers RNA Digital-operated infrastructure with usage-based pricing starting in the $500–$2,000/month range, scaled to cluster size and connector volume (contact sales for exact pricing). The Enterprise tier adds SSO/SAML, dedicated single-tenant VPC deployment, audit logging, 24/7 SLA-backed support, and onboarding workshops under annual contracts typically ranging from $25,000 to $100,000+ per year depending on deployment model, seat count, and support level. Compared to alternatives like Dify Cloud (from $159/month for Pro) or Botpress Enterprise, Agent Cloud's free self-hosted tier makes it significantly cheaper to evaluate and run long-term if you have the DevOps capacity.View Details →
