Backbuild

Backbuild is the platform for SaaS builders who need AI intelligence and mathematically proven software correctness.

The Free tier is a complete workspace: Mail, Chat, Meetings, Calendar, Contacts, Docs, Sheets, Slides, Diagrams, and Photos, with dedicated photo, video, training-video, audio, and music editors, Files, Backbuild Finances, a built-in help desk, and a post-quantum zero-knowledge password and secrets manager. It is also a complete data platform on every tier: custom entity types and entities with typed relationships, saved views, workflows, AI skills, automations, custom tools, the AI assistant, and the full platform REST API, with on-demand containers (including a post-quantum encrypted remote desktop), virtual workers, and video meetings available on usage credits.

Backbuild is AI-native: every capability is exposed to AI agents through the Model Context Protocol (MCP), including full browser and desktop control. Compliance and governance controls (audit logging, role-based access control, organization-scoped permissions) ship on every tier, including Free. The secrets vault uses hybrid post-quantum cryptography (X25519 with ML-KEM-768, NIST FIPS 203) with Argon2id key derivation and is zero-knowledge: secrets are encrypted on the user's device and Backbuild cannot read them.

The Pro and Enterprise tiers add the SaaS Builder (tenants, packages, payments, custom domains, integrations, marketplace) and multi-environment management. Backbuild Science adds research and publishing for students and faculty. Backbuild Prove adds formal mathematical verification of software with HOL-kernel-checked proofs and Lean 4 cross-checks.

Available on the web and as the Backbuild Desktop app for Windows and macOS, with Linux coming soon.
