bolt.diy benchmark

The community built sibling of a commercial product, and the gap between them is the point of measuring it: same interaction model, noticeably less polish in the agent loop. It has one of the widest p10 to p90 spreads in the index, because a run that picks up the wrong model configuration behaves nothing like one that does not. Worth the entry for anyone who needs the whole stack under their own control.

Seeded at launch

The reader scores, lab notes and open ratings published here were written by this lab in August 2026 to populate the reader column before the site had readers. They are not customer submissions, they are not vendor supplied and nobody was paid for them. Anything submitted since then comes from a registered account. The lab index is measured from logged runs and is unaffected either way.

What agent performance looked like in practice

Across 45 recorded executions this product met the published pass criterion cleanly 25 times, partially 10 times and failed 10 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
