Ranked by their public customers on usedby: Braintrust (44 customers), LangSmith (43 customers), and Arize AI (37 customers). ### Which Manufact alternatives offer a free trial? Braintrust, LangSmith, and Arize AI offer a free trial or a free plan, according to their own pricing pages. ### Do Manufact customers use other tools too? None of the 11 Manufact customers on usedby is listed with another tool on this list yet. ### How does usedby rank Manufact alternatives? Only tools of the same or a competing category, from another vendor, count. They are ranked by their public customers at every proof level, job posts included; a tie goes to the stronger proofs (more confirmed, then more observed). Each tool shows its mix: confirmed (a case study, a press release), observed (the vendor’s customer page), signal (a job post, the weakest proof). Shared customers are shown for information and never set the order. Tools of other categories that the same companies use are listed apart, as tools used with Manufact. usedby does not publish departures, so no company is shown switching from Manufact to another tool. --- Source: https://www.usedby.ai/alternatives/manufact · How we check: https://www.usedby.ai/methodology
