🛒 UnderAutomation Licensing & Buying Guide
Welcome! If you are looking to integrate robot control into your software, you likely have questions about how our licensing works, how to get a quote, and what happens after purchase.
This guide acts as a FAQ to clarify the entire process, from your first download to long-term deployment.
1. The Lifecycle: How it Works
We believe in simplicity. No hidden subscriptions, no "per-robot" fees. Here is the journey of a license:
⏱️ Phase 1: The Trial
- Start immediately: Download the SDK (website, NuGet, PyPI, or GitHub) and start your free 30-day trial.
- Need more time? If your Proof of Concept (POC) takes longer than expected, simply use the form on our website to extend your trial.
💳 Phase 2: Purchase & Perpetual Ownership
- One-time payment: When you buy a license, you receive a software key. It's like a password string to use in a
RegisterLicensemethod (no USB key or any license software to install). - Perpetual Use: Your license is yours forever. Even if you never pay us another cent, your applications will continue to work eternally.
- No runtime fees: You can deploy your application to as many customers, robots, or machines as you want.
🛠️ Phase 3: Maintenance & Support
- Included Maintenance: Depending on the license, you get 1 or 3 years of active maintenance. This grants you access to software updates and technical support.
- Renewing (Optional): When maintenance ends, you can choose to renew it for another year to keep getting updates.
- If you don't renew: The maintenance period closes, but your software keeps working. You simply stay on the last version you downloaded.
2. Which License is Right for You?
We used to have a "Site License," but this has evolved into two distinct offers: Standard and Pro. For those needing total control, we offer the Source license.
All licenses are perpetual and allow unlimited redistribution of your compiled application to your customers.
| Feature | Standard 🥉 | Pro 🥈 (Most Popular) | Source 🥇 |
|---|---|---|---|
| Ideal for... | Agile devs, POCs, smaller projects. | Mission-critical production environments. | Total sovereignty & deep customization. |
| Duration | Perpetual | Perpetual | Perpetual |
| Maintenance | 1 Year included | 3 Years included (No paperwork for 3 yrs!) | 3 Years included |
| Redistribution | Unlimited (Commercial allowed) | Unlimited (Commercial allowed) | Unlimited (Commercial allowed) |
| Support | Standard | Priority (<24h) + Remote assistance | Priority + Remote assistance |
| Deliverable | Obfuscated DLL | Obfuscated DLL | Full C# Source Code + VS Solution |
3. The "Source" Advantage
Why do companies choose the Source License? It's about risk management and independence.
- Audit & Compliance: Your security team can audit every line of code.
- Debugging: Step through the library code directly in Visual Studio to understand exactly what is happening.
- Independence: You are not locked into a "black box" vendor. Even if UnderAutomation disappears in 10 years, you own the engine and can maintain it yourself.
- AI Coding Agents: The full source code, combined with the included context files (
AGENTS.md), gives AI coding agents (Claude, Copilot, Cursor, Codex...) precise knowledge of the SDK internals. The LLM understands the code structure and generates accurate, idiomatic integrations instead of guessing from a black-box API.
4. Purchasing, Quotes & Payments
We make the administrative side as frictionless as possible for your purchasing department.
📄 Quotes and Invoices
- Self-Service: You can generate a formal Quote or Invoice (PDF) directly from our order page in your preferred currency (EUR or USD).
- Manual Request: If you have specific vendor forms or need a custom reference, you can handle the process with us via email.
💳 Payment Methods
- Credit Card: We accept payments in USD and EUR.
- Bank Transfer (Wire): We accept wire transfers in EUR to our French IBAN.
- Note: Wire transfers are currently not available in USD.
🤝 Distributors & Resellers

- Become a Reseller: We are always open to new partnerships. Contact us if you wish to distribute our products.
5. Academic & Research Discount 🎓
UnderAutomation actively supports research and education.
If you represent a University or a Public Research Center, you are eligible for a 40% discount on our licenses. This allows students and researchers to access industrial-grade connectivity tools at a budget-friendly price.
6. Technical Compatibility
Regardless of the license you choose, the technology stack remains robust:
- .NET: The core engine. Works with Desktop, Web, APIs, and Services.
- Python: Supported via a wrapper. You get a Python-friendly API while the .NET engine does the heavy lifting.
- LabVIEW: Supported via a set of VIs that wrap the .NET library, designed to fit the native LabVIEW dataflow programming style.
