Backbuild

Backbuild is an AI-native workspace and SaaS-building platform. The Free tier is a complete workspace (Mail, Chat, Meetings, Calendar, Contacts, Docs, Sheets, Slides, Diagrams, Photos, media editors, Files, Finances, a help desk, and a post-quantum zero-knowledge password and secrets manager) plus a data platform with custom entity types, saved views, workflows, automations, and a REST API. Every capability is exposed to AI agents through the Model Context Protocol, including browser and desktop control. Pro and Enterprise add the SaaS Builder: tenants, packages, payments, custom domains, integrations, and a marketplace. Backbuild Prove adds formal, machine-checked proofs of software correctness.
