OpenVault vs Autodesk Vault

What is Autodesk Vault

Autodesk Vault is a product data management (PDM) system integrated with Autodesk's CAD ecosystem. Inventor, Fusion, and AutoCAD connect to a Vault server where files are checked in and checked out, revisions are tracked, and workflows can be enforced. A design change follows a formal check-in ceremony: you have the file exclusively, you make your changes, you check it back in with a comment, and the system records the revision.

Autodesk Vault is a strong fit for teams whose entire workflow lives inside Inventor and Fusion. The integration runs deep. Vault's file state is visible inside the Inventor UI. The check-in process is part of the Inventor save dialog. Revisions and relationships between parts and assemblies are managed at the native object level. If you have a large Inventor assembly with hundreds of parts and sub-assemblies, Vault keeps the interdependencies intact. For those teams, the tight coupling is not friction. It is the whole point.

Vault works on the client-server model. You maintain or subscribe to a server, parts are locked when you check them out, and the network is part of your normal workflow. Teams embrace this because the check-out lock prevents accidental collisions and the server is the single source of truth.

Autodesk Vault requires a license and is purpose-built for the Inventor and Fusion user base.

What is OpenVault

OpenVault is an open-source version control tool for engineering data. It uses Git underneath but wraps the workflow for CAD files. Instead of a check-out lock, OpenVault operates offline-first. You clone a repository, work locally, commit changes, and sync when you are ready or when the network is available. The model is much closer to how software teams use Git than how PDM teams use a locked file system.

OpenVault works with any CAD tool that produces files. SolidWorks, Fusion, CATIA, NX, KiCad, Altium, FreeCAD. It doesn't care what generated the file. It routes large binary files through Git LFS automatically, so a 500 MB assembly stays fast and doesn't bloat the repository. When two people edit the same file, OpenVault flags the conflict and shows both versions so the engineer with design intent can decide what to keep.

OpenVault is free and open source under the MIT license. You install it locally with pip install openvault and start using it immediately. For teams that want a shared web interface, BOM tools, and cloud-hosted repositories, Tool Crib Cloud adds those capabilities on top of the local CLI.

OpenVault's philosophy is that version control should not require a server or a license. The workflow should mirror Git so engineers who have used Git don't stumble. It should work offline. It should handle any CAD tool across all vendors' ecosystems. And it should keep the audit trail as a natural result of doing the work rather than an extra step.

When Autodesk Vault is the right choice

You are entirely on Inventor and Fusion. If your engineering organization uses Inventor for mechanical design and AutoCAD for drawings, Vault is purpose-built for you. The integration is native, the workflows are familiar to Inventor users, and the system understands the relationships between Inventor parts, assemblies, and drawings automatically.

You need formal change control and workflow enforcement. Vault can enforce approval chains, state machines, and review gates. If a design change must pass through an ECN (Engineering Change Notice) process, Vault can model that. It can prevent a file from moving to production status until all approvals are signed off.

Your team expects a central server and lock-based concurrency. Some teams prefer the guarantee that only one person can edit a file at a time. Vault's check-out lock gives you that. You do not have to think about merging conflicts because Vault prevents them outright. If your team likes this model and has people who manage the Vault server, it removes a class of problems.

You work in a regulated industry and need documented audit trails with legal weight. Vault's audit log is designed for compliance. The server is the single source of truth. If you need to prove that file version 5.2 was approved and sealed at a specific time, Vault's server-based log is evidence. Some teams in aerospace and medical devices have audit procedures that assume a central server is the keeper of the record.

You want vendor support and integration with Autodesk's broader ecosystem. Autodesk stands behind Vault, provides official support, and integrates it with Fusion Manage for enterprise-scale PLM. If your company has an Autodesk account manager or a Fusion Manage subscription, Vault integrates cleanly.

When OpenVault is the right choice

You use multiple CAD tools and need one version control system. A modern engineering team might use SolidWorks, Fusion, FreeCAD, and KiCad in the same company. Vaults and PDM systems are usually tied to one CAD platform. OpenVault treats all files equally. One repository tracks SolidWorks parts, STEP files, Fusion designs, KiCad schematics, and BOMs together. Your audit trail covers the entire product across every tool in use.

You want version control without a server or license. OpenVault is free, open source, and runs on your laptop. No server to set up, no per-seat licenses to negotiate, no network dependency. You install it with pip and start working. For solo engineers or small teams, this removes complexity. For larger teams that want to share repositories, Tool Crib Cloud adds web collaboration without the overhead of running a managed server.

Your team already knows Git. If your mechanical engineers, electrical engineers, and software engineers all speak Git, OpenVault feels native. The commands are Git commands. The mental model is Git. You branch, commit, merge, and diff the same way you do with source code. There is no new learning curve because you already know the system.

You work offline and need version control that does not require the network. OpenVault is offline-first. You clone, work locally, and sync when ready. No locked-out moments when the server is slow or down. No latency on every save. You can travel, work on an airplane, and sync when you land. Git operates the same way, and OpenVault inherits it.

You need honest conflict resolution for CAD files. Autodesk Vault prevents conflicts by locking files. OpenVault accepts that conflicts happen and shows you both versions when they do. Automatic merging of 3D geometry is an unsolved problem. Some teams prefer to see both versions and decide with design intent rather than prevent the situation entirely.

You want to version control non-CAD engineering data alongside your models. Specifications, test reports, simulation results, and manufacturing drawings are often stored separately from the CAD system. OpenVault version controls them together. You commit a design change and its associated test report and BOM in one atomic change. They never drift apart.

You need an alternative to PDM because overhead or cost is the barrier. If you have evaluated SolidWorks PDM, Vault, or Windchill and the barrier is complexity, per-seat licensing, or server maintenance, OpenVault removes all of that. It is lightweight, free, and straightforward.

The architecture and workflow difference

Autodesk Vault: Check-out, edit, check-in. You request a file, Vault locks it and gives it to you, you edit it, you save it, and you check it in with a message. While you have the lock, no one else can edit it. This prevents conflicts by preventing simultaneous edits.

OpenVault: Clone, branch, commit, sync. You clone the repository once, create a branch for your work, commit changes locally, and push when ready. Multiple people can edit different files at the same time. If two people edit the same file, OpenVault flags it and you resolve it together.

The Vault model is familiar to PDM users and older version control systems. The OpenVault model is how modern software teams work. Neither is inherently right. The right one depends on how your team prefers to coordinate.

Multi-CAD teams: the strongest case for OpenVault

A composite manufacturing company uses CATIA for structural design, FreeCAD for fixture design, SolidWorks for mechanical subassemblies, KiCad for electronics, and Fusion for rapid prototyping. No single PDM system speaks all of them natively. Some tools integrate with Vault or PDM, others do not.

OpenVault tracks all of them in one repository. A BOM edit, a structural change, and an electrical schematic update travel together as one commit. The audit trail is unified. When you ask "what changed on January 15?", you see all the changes across all the tools, all the authors, all the messages. That visibility matters when you need to trace dependencies.

Autodesk Vault would integrate Fusion and Inventor pieces but not the CATIA or KiCad parts. You would split version control across two systems, and the dependencies between them would have to be managed manually.

Trying each one

OpenVault is easy to try. Install it with pip install openvault, run openvault init, and start committing files. The CLI is free. The learning curve is one tutorial if you know Git. You can try it on a real project this week. If it does not fit, delete it. No server, no license negotiation, no vendor involvement.

Autodesk Vault requires infrastructure. You need a server instance or a subscription through Autodesk. Setup takes longer. Trying it on a real project takes more coordination. But the payoff is that if you commit to it, the integration with Inventor and Fusion is seamless. The investment in setup is paid back by the integration quality.

Making the choice

Start with these questions:

1. Do you use only Inventor and Fusion? If yes, Autodesk Vault is a strong first choice. Its integration is unmatched for that ecosystem.
2. Do you use multiple CAD tools or non-CAD engineering files? If yes, OpenVault is likely simpler. One system, one audit trail, one workflow.
3. Do you have a strong preference for check-out locks or for offline-first branching? This is a philosophy question. Locks are safer against some kinds of mistakes. Branching is more flexible and requires more discipline. Both work.
4. Do you need formal change control workflows and approvals? Vault can enforce them. OpenVault is data-centric and leaves approval workflows to your process, your tools, and your team.
5. Do you want to run software on your own infrastructure or use a hosted cloud system? Vault is server-based (you manage it or Autodesk manages it). OpenVault CLI is local. Tool Crib Cloud adds hosted repositories if you want cloud without the server burden.
6. What is the barrier today? If you have no version control, either is better than nothing. If you use PDM and it feels too heavy, OpenVault might be the relief you need. If you use nothing and your CAD ecosystem is all Inventor, Vault is the purpose-built answer.
