Schematic design
Create the logical netlist by placing components and splices, connecting pins and defining conductors on connections.
HarnessHive
HarnessHive is a browser-based CAD workspace for designing electrical wiring harnesses, combining schematic, routing, BOM and cut-list, and true-to-scale formboard views in one live document. It supports collaborative design teams with version history, part libraries, manufacturing exports and an AI assistant for reviewable design proposals.
Browser-based wiring harness CAD
HarnessHive is a browser-based CAD workspace for designing electrical wiring harnesses. It combines schematic, wiring, bill of materials and cut-list, and true-to-scale formboard views in one live document, so changes to the design can flow into related manufacturing information.
The product is intended for harness engineers and teams that need to design, review and hand off harnesses collaboratively. It includes real-time editing, version history, part libraries and exports for drawings, spreadsheets and harness data, while its AI assistant can inspect a harness or prepare changes as proposals for review.
Core features
Wiring and routing
Define connector locations, branch points, routes and coverings for the physical harness layout.
Live BOM and cut list
Use one live model to derive parts, cut lengths and BOM rows, then export the BOM and cut list as XLSX.
To-scale formboard
Maintain a manufacturing drawing at true 1:1 scale and export it as a full-size PDF for a build board.
Collaboration and version history
Edit the same harness with live cursors and presence, per-user undo, read-only history and snapshots, and Admin, Editor and Viewer roles.
AI-assisted proposals
Ask the in-editor assistant questions about a harness, attach CSV wire lists, use supplier pages to create parts, or generate a reviewable proposal; changes are applied only after approval.
Practical use cases
Startups and machine builders
Build a first harness in the browser using linked schematic, routing, BOM and formboard views instead of maintaining separate documents for each representation.
Collaborative engineering teams
Let multiple contributors edit and review the same harness, with role-based access and history that preserves prior work between design sessions.
Harness production handoff
Hand a manufacturing shop a true 1:1 formboard PDF and an XLSX BOM and cut list derived from the current harness model.
AI-assisted design exploration
Attach a CSV wire list or ask questions about an open harness, then review and apply the assistant's proposed parts, connections or larger harness changes.
Reusable parts management
Keep connector, terminal, conductor, seal and splice definitions in organization or local libraries while pinning the exact version used by each occurrence.
Pros and Cons
Pros
- Combines schematic, physical wiring, BOM and cut-list, and a 1:1 formboard in one live harness document.
- Supports real-time collaboration with per-user undo, read-only history and role-based access.
- Provides practical manufacturing outputs, including full-size formboard PDFs and XLSX BOM and cut lists.
- Uses versioned parts and libraries, pinning the exact part version used by each harness occurrence.
- AI changes are presented as reviewable proposals instead of being applied automatically.
Cons
- The AI assistant is a beta feature and uses a shared per-workspace quota that resets daily.
- KiCad and Onshape importers are listed as coming soon rather than currently available.
- The available evidence does not specify broader import formats, browser requirements or detailed collaboration limits.
FAQ
Is there a free trial?
Yes. HarnessHive offers a 14-day free trial with no credit card, and the full product and AI assistant are included during the trial. Nothing charges automatically when the trial ends.
How does HarnessHive fit into a harness-design workflow?
HarnessHive runs in a browser, with no installation required. The site describes a live document that combines schematic, wiring, BOM and cut-list, and formboard views.
What files can HarnessHive export?
A harness can be exported as a true 1:1 formboard PDF, schematic and wiring sheets as PDF, a BOM and cut list as XLSX, and complete harness data as JSON. KiCad and Onshape importers are described as coming soon.
How are team members and roles handled?
Every person in a workspace uses a seat, including people who draw, review or only read harnesses. The available roles are Admin, Editor and Viewer.
Are the AI assistant and MCP server unlimited?
The AI assistant and MCP server are included in the plan and trial, but usage is subject to a shared workspace quota that resets daily. The assistant is identified as a beta feature.
