We've made our testing table more keyboard-friendly, allowing you to bulk delete rows and copy multiple values at once.

You can now add additional columns that act as helper variables for assertions (JavaScript, LLM assertions). Place the correct answer in these helper variables and use them in assertions for more efficient and accurate testing.

Based on user feedback, we've improved LLM assertions. Now, the entire conversation history is included in the context, providing a more comprehensive view for better testing.

You can now use multiple messages in the “messages” column. Currently, it's possible to simulate user and assistant messages. We're working on the ability to mock Tools and upload images for Vision testing.

Tests are a big focus for us, and we're committed to continuously improving them.

Stay tuned for more updates!

We're excited to announce significant updates to Langtail's table component aimed at improving your test-writing experience:

Stay tuned! We're in the process of developing an "LLM as a judge assertion" feature, set to take our testing capabilities to the next level. More updates coming your way soon!

We're thrilled to introduce our new dashboard view! Now serving as the main hub for each project, the dashboard provides a snapshot of your project's activity and performance at a glance. With recent logs and quick statistics, you can stay updated the moment you log in.

The first version of the Langtail SDK is now live! 🥳 The SDK can function as an OpenAI proxy and is also compatible with prompts directly deployed within Langtail. Dive into the details over at our GitHub docs.

Currently, we've rolled out the JS SDK. If you're interested in a Python SDK, we'd love to hear from you.

We've released a new video that's now featured on our homepage. Get a quick overview of what Langtail offers by watching our latest video.

We're happy to announce that you can now embed publicly shared prompts into iframes! Here's a quick example:

We've significantly expanded our documentation to help you hit the ground running:

Sharing is caring, and we've made it even better! When you share a prompt publicly, we'll automatically generate an OG image for you.

Tired of hardcoding API endpoints and keys directly in code? We've got you covered! Introducing project-level environment variables:

Our brand new website is live, showcasing the four key features that make Langtail the ultimate tool for prompt engineering:

We've got a pricing plan for everyone! Choose from three tiers:

We've been busy expanding our documentation to help you get the most out of Langtail. Head over to our docs page to explore the latest information and guides.

Already building your application using the OpenAI SDK? No problem! With Langtail Proxy, you can experiment with Langtail without migrating your prompts. Here's how:

We've also released some handy enhancements to make your life easier:

Chatbots can now stay up-to-date with the current date! Introducing the helper, a new feature designed to keep your chatbots in sync with real-time.

Say hello to granular control over your logs. You can now filter logs by any column, even custom-send metadata. Find what you need, when you need it.

Ever wondered about our pricing? We've just launched our pricing page, making it easier for you to find the perfect plan for your needs. Check it out!

Good news, everyone! We've just launched a new feature that lets you publicly share your prompts. Previously, users needed an account to view a shared prompt, but now, anyone can view it thanks to our new read-only Playground view. 🎉

In the read-only Playground, you can see all messages, variables, and Tools (functions). It's an open window to the world of your prompts. Currently, only a fixed version of the prompt can be shared, but we're already working on updates that will let you share and always view the most recent version of a prompt.

We've made some significant improvements to our developer experience for JavaScript assertions in Tests:

We're excited to announce that we've released support for a templating engine, based on Handlebars! With this new feature, you can now tackle more complex use cases, including:

Simply deploy a prompt with this template, send the correct variable, and watch as the final version of the prompt resolves. You can then view this in the Logs. This added flexibility opens up a world of possibilities for your prompt handling.
