Linden
Validate AI Outputs Before They Reach Your Application
LLMs can generate malformed JSON, missing fields, schema violations, and inconsistent outputs that break production applications. Linden is an AI reliability layer that validates structured AI responses before they reach your system. Define schemas and business rules, then receive clear validation decisions: ALLOW, WARN, REGENERATE, or BLOCK. Integrate in minutes using our API and Python SDK.
Hi everyone! 👋
I built Linden after repeatedly running into the same issue while working with LLMs: AI outputs often look correct but fail because of malformed JSON, missing fields, schema violations, or inconsistent data. Most applications either trust the response or write custom validation logic from scratch.
Linden provides a reliability layer between your AI model and your application. You define the expected schema and validation rules, and Linden returns a simple decision—ALLOW, WARN, REGENERATE, or BLOCK—before the response reaches production.
This MVP includes:
Python SDK
API key authentication
Schema validation
Business rule validation
Validation history and analytics
This is my first SaaS launch, and I'd genuinely appreciate any feedback, feature requests, or ideas. Thanks for checking it out! 🚀

Who hunted Linden?
Linden was hunted by Harleen. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
