TaLibStandard is open source (GPL-3.0) for individual and research use.
For commercial applications, we offer flexible licensing and support options.
| Use Case | License |
|---|---|
| Personal projects, research, academic use | ✅ GPL-3.0 (free) |
| Startup / bootstrapped product | ✅ GPL-3.0 (free, GPL terms apply) |
| Commercial SaaS or proprietary software | 💼 Commercial license required |
| Trading firm / hedge fund / prop shop | 🏢 Enterprise license |
| Cloud API or hosted service | ☁️ Enterprise / OEM license |
GPL-3.0 means: If you distribute a product that includes TaLibStandard, your product must also be open source under GPL-3.0. If you need to keep your code proprietary, a commercial license removes this requirement.

Q: Can I evaluate TaLibStandard in a commercial project before purchasing?
A: Yes. You can use the GPL-3.0 version for a 30-day evaluation. After 30 days, a commercial license is required for production use in proprietary systems.
Q: Does the commercial license cover NuGet packages?
A: Yes — Atypical.TechnicalAnalysis.Functions and Atypical.TechnicalAnalysis.Candles are both covered.
Q: What happens if I upgrade my team size?
A: Contact us. We'll prorate the upgrade to your current license period.
Q: Is source code access included?
A: Yes — the source is on GitHub. The commercial license grants you the right to use it in proprietary software, not a separate private build.
Q: Do you offer volume discounts for multi-year contracts?
A: Yes. Contact us for multi-year or multi-product quotes.
