Use the right notation for every discipline
Each team works with focused libraries, connectors, metadata, starters, and checks designed for its discipline.
- Eight engineering disciplines
- 1,000+ editable symbols
- 27 specification-backed connectors
For multidisciplinary engineering teams
Build the complete system together.Without losing the details that matter.
Bring software, cloud, data, network, DevOps, electrical, mechanical, and robotics specialists into one governed workspace. Co-edit live diagrams, link specifications and decisions to exact work, and keep every review in context.
- Live diagrams + specs
- Roles + restricted projects
- SSO + MFA
- Versions + audit

System spec synced12 linked diagrams
One organization, many engineering languages
Specialized work. Shared system context.
Struct avoids the two common extremes: isolated discipline tools with no common view, or generic canvases that strip away the meaning engineers need.
Connect specifications across disciplines
Connect requirements and decisions to whole diagrams, exact nodes, relationships, or other specifications with a navigable way back.
- Visual and Markdown authoring
- Bidirectional references
- Markdown, HTML, and Word export
Collaborate on one current system
Co-edit diagrams and specifications, preserve versions, and use expiring links for controlled asynchronous review.
- Authenticated live sync
- Conflict-aware versioning
- Review links and audit events
Teamwork in Struct
One controlled project record across engineering disciplines.
Teams can work in focused diagram languages while shared interfaces, specifications, versions, reviews, and access controls stay connected.
- 01Organization and project rolesOwner, admin, member, and viewer access with explicit grants for restricted projects.
- 02Cloud synchronizationNodes, relationships, annotations, metadata, Specifications, and presentation order update together.
- 03Review threads and versionsAnchor feedback, save named checkpoints, and preserve decisions beside the engineering state.
- 04Controlled sharingCreate review and live links with project policy, expiration, and audit context.
From concept to controlled record
A collaboration model that scales with the work.
Start privately, invite the right specialists, and add governance as the system becomes a shared organizational asset.
Create the organization and project
Keep teams, seats, projects, retention, and policy isolated within the correct organizational boundary.
Invite each discipline
Assign owner, admin, member, or viewer roles and restrict sensitive projects to explicit grants.
Build diagrams and specifications live
Synchronize nodes, routes, annotations, metadata, and linked specifications as the team works.
Review, version, and present
Save durable versions, share expiring reviews, inspect audit events, and explain the system with animated walkthroughs.
Governance without ceremony
Control access. Preserve evidence. Keep moving.
Organization features are designed to make engineering work easier to trust without turning every change into an administrative workflow.
People and roles
Manage seats, expiring invitations, tenant switching, role assignments, and immediate suspension from one organization boundary.
- Owner, admin, member, viewer
- Seat reservations and invitations
- Project-level restricted grants
Identity and security
Use Argon2id password sign-in, TOTP MFA with recovery codes, or enterprise OpenID Connect SSO with PKCE.
- Verified email and domain allowlists
- Just-in-time SSO provisioning
- Revocable sessions and review links
History and evidence
Preserve project versions, organization audit events, retention settings, and the decision context attached to the architecture.
- Conflict-safe version history
- Reviewable organization events
- Configurable retention
