Backbuild

Backbuild is a complete workspace you can use to run daily work and, with Pro, build and ship products. The Free plan bundles mail, calendar, contacts, files, docs, sheets, slides, diagrams, and photo/video/audio/music studio editors—so you can handle content, collaboration, and operations in one place.

Beyond the workspace, Backbuild is also a platform for SaaS builders and AI-driven workflows. It includes typed data modeling (custom entity types and entities with typed relationships), saved views, workflows, AI skills, automations, custom tools, an AI assistant, and a full platform REST API. You can run on-demand containers, virtual workers, and encrypted remote desktop and meetings (on usage credits).

Backbuild is designed for AI agents via a full MCP surface: mail, docs, billing, containers, and the secrets vault can be controlled by AI agents with browser and desktop control. It also includes governance features such as audit logging, role-based access control, and organization-scoped permissions on every tier.

If you want research or correctness guarantees, Backbuild Science and Backbuild Prove extend the platform: Science focuses on LaTeX-based research and proof tooling, while Prove adds formal mathematical verification with HOL-kernel checking and Lean 4 cross-checks (for supported languages). Backbuild is available on the web and as a desktop app for Windows and macOS (Linux coming soon).

What is Backbuild’s core product—workspace, platform, or both?

Both. Backbuild includes a complete workspace on Free, and it also provides a build-and-ship platform with a REST API, data modeling, workflows, and AI tools (with Pro features for shipping products).

Is Backbuild’s secrets manager zero-knowledge?

Yes—secrets are encrypted on the user’s device before they reach Backbuild, so Backbuild cannot read the stored secrets even if compelled to try.

What does “AI-native with MCP” mean in practice?

Every capability is exposed to AI agents through the Model Context Protocol (MCP), including full browser and desktop control. This lets agents interact with features like mail, docs, and other platform functions.

Do governance and compliance controls require upgrading?

No—audit logging, role-based access control, and organization-scoped permissions are included on every tier, including Free.

What are Backbuild Science and Backbuild Prove used for?

Backbuild Science supports research and publishing workflows with proof tooling and exports. Backbuild Prove focuses on formal mathematical verification for supported languages, using HOL kernel verification and a Lean 4 cross-check.

Where can I use Backbuild?

Backbuild is available on the web and as a desktop app for Windows and macOS, with Linux coming soon.
