Free due diligence software: what to look for
“Free due diligence software” usually means one of three things: a single-purpose lookup (one registry), a paid platform with a limited trial, or a genuinely free multi-source tool. Here is how they differ and what to look for — and where OpenDD fits.

The questions that matter: How many types of check does it run (just company info, or IP, litigation, sanctions and trust too)? Does it cite primary sources you can verify, or opaque aggregated data? Is it actually free, or a trial that expires? And can you export a report? Many free tools do one thing; few do the full workup without a paywall.
How OpenDD compares
| Capability | Single-purpose free tools | Paid platforms (trial) | OpenDD |
|---|---|---|---|
| Corporate & financial | Sometimes | Yes | Yes, free |
| IP (patents/trademarks) | Rarely | Add-on | Yes, free |
| Litigation records | Rarely | Yes | Yes, free |
| Sanctions screening | Sometimes | Yes | Yes, free |
| Security/privacy posture | No | Add-on | Yes, free |
| Primary-source citations | Varies | Varies | Always |
| Report export | Rarely | Yes | Yes, free |
| Price to start | Free | Trial then paid | Free |
The bottom line
If you only ever need one registry lookup, a single-purpose tool is fine. If you need a defensible, multi-angle workup — corporate, IP, litigation, sanctions and trust — without a paywall, that is exactly what OpenDD is built for. Browse the full toolkit or read how to do due diligence for free.

Frequently asked questions
What is the best free due diligence tool?
The best free tool is one that runs multiple check types (corporate, IP, litigation, sanctions, trust), cites primary sources you can verify, and lets you export a report at no cost. OpenDD is built to do all of these on a free plan.
Is free due diligence software reliable?
It is as reliable as its sources. Prefer tools that link every finding to a primary source (registries, court dockets, filings) so you can verify it yourself, rather than opaque aggregated scores.
Can I export a report from a free tool?
With most single-purpose free tools, no. OpenDD lets you export Word and PDF reports on the free plan.
