T Thoma

PLM for small + mid-size manufacturers

Documents. BOMs. Changes.
Workflows. Done.

Thoma is a native Windows PLM that runs on your own server. Install in minutes, bring your own data, and stop fighting the cloud-only incumbents.

No credit card. 15 seats included on the trial.

Everything a small engineering team needs

The PLM tools your shop has been faking with shared drives and spreadsheets — built into one Windows-native application.

Document control

Versioned documents with check-in / check-out, audit trails, and watermarked outputs.

Bills of materials

Multi-level BOMs with where-used, effectivity, and revision tracking.

Change requests

Engineering change orders with affected documents, approvers, and full history.

Workflows

Configurable approval flows for documents, parts, and process changes.

Project management

Stage-gate templates, baselines, Gantt, budget, ROI, gate reviews — full PM subsystem, not a bolt-on.

SolidWorks + Office add-ins

Check files in and out without leaving SolidWorks, Word, Excel, or PowerPoint.

Native Windows install

One installer, portable Postgres bundled, runs on your hardware. No SaaS lock-in.

Install on your hardware. Own your data.

Thoma ships as a single native Windows installer with portable Postgres bundled. No SaaS account, no per-document upload fees, no cloud-vendor lock-in. Your CAD drawings, BOMs, and change history live on a server you control.

Air-gapped deployments are first-class. Many of our customers are CMMC-adjacent and can't put controlled-document data in someone else's cloud.

# Install on a Windows server
> thoma-installer-1.0.0.exe
# That's it. Tray icon comes up.
# Open the admin URL, set your first admin,
# import your trial license, log in.

Try it before you commit

The live demo lets you click around a working Thoma instance with realistic data — no signup, no install. Tenants reset after 6 hours of inactivity.
