Top Recommended Replacements
InvenTree
Best Overall FOSS Alternative
Why we like it
The most modern open-source inventory and part management system; features native KiCad integration via a database library plugin; allows for full stock tracking and BOM management.
Keep in mind
Requires self-hosting (Docker/Python); lacks the native 'live' 3D MCAD synchronization that Altium offers out of the box.
PartKeepr
Runner Up
Why we like it
Dedicated specifically to electronic component management; handles large libraries with complex technical parameters and multi-supplier data; 100% free.
Keep in mind
The user interface is dated (PHP-based); development is less active compared to InvenTree; integration with modern ECAD tools requires manual database mapping.
Ki-nTree
Best for Quick Library Building
Why we like it
Specifically designed to automate the 'Part Request' workflow; pulls data directly from Digi-Key, Mouser, and Element14 into your InvenTree or KiCad library.
Keep in mind
It is a utility script/tool rather than a full standalone management server like Altium Vault.
OpenBOM (Free Tier)
FREEBest for Supply Chain Collaboration
Why we like it
Cloud-native platform focused on the Bill of Materials (BOM); the free tier allows for basic BOM management and vendor tracking; great for small teams moving to production.
Keep in mind
Proprietary; the free version has significant limits on the number of users and advanced inventory functions (like PO generation).
LibrePLM
Best for Integrated Product Lifecycle
Why we like it
An open-source PLM integrated with Odoo ERP; handles version control and engineering information directly; great for teams that want to manage the whole product, not just the PCB.
Keep in mind
Geared more toward mechanical engineers; requires a solid understanding of the Odoo ecosystem to implement successfully.
KiCad Database Libraries
FREEBest for Native KiCad Users
Why we like it
Allows KiCad to pull component data from a central SQL database (like MySQL or PostgreSQL); provides a 'Single Source of Truth' similar to Altium's vault architecture.
Keep in mind
Requires you to manage your own database and write the SQL connectors; no built-in web UI for part requests or lifecycle state management.
PartsBox (Free Plan)
FREEBest for Small Stock Tracking
Why we like it
Incredibly user-friendly interface; free for hobbyists/small projects; includes an excellent search engine for parts and automated pricing updates from distributors.
Keep in mind
The free tier is strictly for non-commercial use; business plans are subscription-based and can scale in cost similarly to Altium's offerings.
Aras Innovator (Open Release)
FREEBest Enterprise-Grade FOSS
Why we like it
A massive, scalable PLM platform used by global corporations; the 'Open Release' allows for deep customization of electronic design lifecycles.
Keep in mind
Extremely complex to install and manage; the community version lacks some of the automated 'Connectors' for ECAD software.
EasyEDA Library
FREEBest for Cloud-Only Teams
Why we like it
Completely cloud-integrated library management; automatically synced with LCSC (supplier) data; zero setup required for team-based part sharing.
Keep in mind
Proprietary; data is stored on EasyEDA servers; limited flexibility for those who want to host their own 'private' vault.
Bomist (Free Plan)
FREEBest Desktop Client
Why we like it
Native desktop app (Windows/Mac/Linux); very fast; handles inventory and part data locally with a beautiful UI; free for small personal libraries.
Keep in mind
Not open source; team collaboration features (which mirror Altium Vault) require a paid monthly subscription.
Odoo PLM
Best for Manufacturing Integration
Why we like it
Integrates BOMs directly with your manufacturing (MRP) and inventory modules; handles engineering change orders (ECO) natively.
Keep in mind
The 'PLM' module is an enterprise app in the Odoo ecosystem, meaning it's only free if you use the Odoo Community version and a third-party plugin like LibrePLM.
GitHub/GitLab (for Designs)
FREEBest for Project Versioning
Why we like it
Best-in-class for managing project files and schematics; can be paired with 'Altium-to-Git' scripts to handle the revision management part of Altium Vault for $0.
Keep in mind
Does not handle 'Components'—strictly a file-level version control system; lacks supply-chain/part-parameter awareness.
