Basalt, #1 AI observability tool for teams, is launching its brand new Agent Builder : prototype, test, and deploy complex AI flows composed of multiple prompts, and run them through a dataset of scenarios.
Thanks Nicolas for the hunt !
I’m François, co-founder of Basalt, and together with the team we’re super excited to share our brand new feature: the Agent Builder 🚀
What pain are we solving ?
We're experts in AI observability, and along the way we noticed something important: engineers and PMs want to prototype AI agents before shipping them, but workflow builders are not made for evaluations.
What’s new with our Agent Builder
Basalt's Agent Builder is the easiest way to design, test, and optimize complex AI flows built from sequences of prompts and actions.
👉 Create and customise your own flows
👉 Chain prompts and actions with ease
👉 Run each prompt on the best-suited model
👉 Set custom evaluation criteria for each step
👉 Measure performance on hundred of real case scenarios with dedicated datasets
Stop testing prompts in isolation. Turn your flow into a single, end-to-end workflow you can evaluate thoroughly, and then deploy with confidence.
Hope you enjoy it !
❤️ from the Basalt team
Friends don’t let friends building AI apps without proper logging, and evaluation.
Basalt is the go to tool, easy to install, simple to setup.
Great to see the improvements from v1
I’m Guillaume, co-founder of Basalt, and today we’re introducing a major step forward in how teams build with AI: the Basalt Agent 🎉
Until now, prototyping agents meant juggling between workflow tools, prompt sandboxes, and spreadsheets, but none of them were really made for evaluation.
That’s the gap we’re closing.
With Agent Builder, you can:
🔗 Chain prompts and actions effortlessly
🤓 Assign each step to the best model for the job
📐 Define your own evaluation metrics
📊 Run large-scale tests on real-world scenarios
From your first chained prompt, to complex multi-turn agentic workflows, Basalt gives you a single place to design, test, and optimize, before you ever ship.
This one’s for everyone who’s ever said, “I just want to see how it performs in context.”
Now you can.
Thank again to @picsoung for the hunt! I hope you’ll enjoy using it as much as we enjoyed building it 💛
This looks amazing, François! 👀 How does the evaluation part work across different models?

Excellent! Can agents hit my own retrieval system when testing?
Basalt
@pierre_lemaire Yes it can! You can use API Request node to ping your system or even soon a code block :)
Basalt
@pierre_lemaire absolutely ! You can implement your own retrieval system in the workflow builder and test how well it performs

That’s a solid upgrade! Congrats.
