Top Recommended Replacements
OpenBOM (Free Tier)
FREEBest for Small Hardware Teams
Why we like it
The 'Free User' plan allows for unlimited multi-level BOMs and item catalogs; includes an 'Excel-like' collaborative interface that is much faster to set up than Arena.
Keep in mind
The free version is strictly for one user; advanced Change Management (ECOs) and ERP integrations require moving to a paid subscription.
Aras Innovator (Community Edition)
Best Enterprise-Grade FOSS
Why we like it
A massive, scalable PLM used by global corporations (like Airbus and Microsoft); the 2025 Community Edition is free for up to 50 users and includes core 'Product Engineering' modules.
Keep in mind
Extremely complex to install and maintain; requires Windows Server and SQL Server; lacks the automated 'Connectors' for CAD found in the paid subscription.
Odoo PLM
Best for Manufacturing Integration
Why we like it
The 'One App Free' plan allows you to use PLM for $0; handles engineering change orders (ECOs) and versioning directly alongside manufacturing and inventory.
Keep in mind
Adding a second integrated app (like Inventory) triggers a per-user cost; the open-source Community version lacks some high-end security features of the Enterprise suite.
Ganister PLM
Best for Graph-Based Data
Why we like it
Modern 'Graph-powered' PLM that excels at showing relationships between parts, requirements, and documents; very fast and responsive web UI; open architecture.
Keep in mind
Requires technical knowledge of Node.js and Neo4j for self-hosting; smaller community compared to Aras or Odoo.
Duro (Free Tier)
FREEBest for Rapid Startup Scaling
Why we like it
Designed specifically for agile hardware teams; emphasizes 'Simple PLM' over complex configuration; free tier for early-stage teams to manage parts and BOMs.
Keep in mind
Proprietary code; the free version limits the number of active products and total storage.
InvenTree
Best for Electronic Components
Why we like it
Exceptional at managing part libraries and stock; integrates directly with KiCad; handles BOM rollups and multi-location inventory for $0 if self-hosted.
Keep in mind
More focused on PDM/Inventory than full 'Lifecycle' workflows like stage-gate approvals or quality management (QMS).
Propel (Free Demo)
Best for Salesforce Users
Why we like it
Built natively on Salesforce, allowing your sales/marketing teams to see the same product data as engineers; excellent for 'Customer-Centric' PLM.
Keep in mind
No permanent free tier; pricing is enterprise-level, though it is often cited as easier to use than Arena.
FusePLM
FREEBest for Simple Workflows
Why we like it
Specializes in 'no-nonsense' change management; includes a free tier for very small teams to manage a single product lifecycle; highly intuitive card-based UI.
Keep in mind
Proprietary; the free version is very restricted; lacks the deep compliance tools (like 21 CFR Part 11) found in Arena.
BeProduct (Free Tier)
FREEBest for Soft Goods/Apparel
Why we like it
Tailored for consumer goods and fashion; handles tech packs and supplier collaboration with a visual-first approach; free tier for individuals/small designers.
Keep in mind
Not designed for complex electronics or medical devices with rigid compliance requirements.
OpenPLM
Runner Up (Legacy Choice)
Why we like it
A mature, Django-based PLM that focuses on 'Parts' and 'Documents' as the core of the digital thread; 100% free.
Keep in mind
The user interface is very dated; development has slowed significantly in recent years compared to modern tools like Ganister.
LibrePLM
Best for Odoo Power Users
Why we like it
A dedicated open-source bridge for Odoo; provides advanced PLM features like engineering change management for $0; keeps data private on your own server.
Keep in mind
Dependent on the Odoo ecosystem; requires technical server management.
GitHub (with PLM scripts)
FREEBest for 'PLM-as-Code'
Why we like it
By using JSON/YAML for BOMs and Git for version control, many startups build a 'Free PLM' stack using GitHub Actions for release approvals.
Keep in mind
Zero built-in 'Part' awareness; lacks the UI for procurement or inventory management.
