Best for: Release0
Release0 is a no-code builder for conversational AI agents, positioned for the case where the agent is a standalone destination rather than a widget bolted to the corner of a website. Agents are built as chat workflows in a visual editor, deployed globally across multiple regions in seconds, and given their own custom domain with an SSL certificate and full custom branding — plus QR codes, link previews, password protection and expiration dates, which together make it as suitable for a printed campaign or a gated internal form as for a support bot. That framing shows up in the metering too: plans are counted in agents and submission chats rather than in seats, so a team can run hundreds of separate small agents without paying per person. Analytics are a first-class part of the product rather than an afterthought — advanced analytics on every tier, a real-time event stream from the Pro tier up, and retention scaling from three months to five years — and a live dashboard can be shared publicly with clients or stakeholders through a single link. Everything is mobile-ready by default, and workflows can be imported and exported, which is the feature that makes agent templates reusable across clients. It integrates with OpenAI, Zapier and Google Sheets, and tagging supports segmenting agents at scale.
Ideal use cases:
- •Teams or individuals who need visual no-code builder for conversational agent workflows
- •Teams or individuals who need multi-region deployment with custom domains and ssl
- •Teams or individuals who need custom qr codes, password protection and expiration dates per agent
- •Teams or individuals who need publicly shareable real-time analytics dashboard
- •Anyone focused on no-code workflows
- •Anyone focused on chatbot-builder workflows
