Good to be back on Product Hunt! 🚀 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 💛 — The Basalt team
