Langtail is an LLMOps platform that helps teams speed up the development of AI-powered apps and ship to production with fewer surprises. With Langtail, you can debug prompts, run tests, and observe what’s happening in production.
👋 Hi Product Hunters! I’m Petr, co-founder and CEO of Langtail.
Over the past year, I’ve spoken with dozens of founders and engineers about their experiences building AI-powered apps. I heard from almost everyone that taking an app from a simple demo to a great product that can be shipped to users is HARD WORK. Some of the common challenges I heard:
- LLMs can be unpredictable, making traditional testing tools more frustrating than helpful.
- Writing a good prompt is an art form, and sometimes the best person for the job isn’t an engineer - which is a problem if all of the prompts live in git.
- The best practices for using LLMs are constantly changing as new models are released and as teams get more experience.
We built Langtail to address the pain points that a team experiences as they take their proof-of-concept and turn it into a real product.
Here are the top features in Langtail:
🧪 **Playground:** Debug and collaborate on prompts with your team.
✔️ **Tests:** Create a suite of tests to evaluate how changes affect your prompt’s output.
🚀 **Deployments:** Publish prompts as API endpoints, allowing you to easily invoke them from your app.
📊 **Observability:** Logs provide insight into how your prompt is responding to real-world users and metrics help you monitor key metrics like latency and cost.
