The median turn latency is 85.2 seconds per prompt, not per whole build, which derives to 12.8 min across the full nine prompt specification. That is a tenth percentile of 52.6 seconds and a ninetieth percentile of 133.1 seconds across 45 recorded executions.

How reliable is Lovable?

82.2% of recorded executions met the published pass criterion with no operator intervention. 6 were partial and 2 failed outright. Every one of those rows is published on this page.

Can I export the code from Lovable?

Full source export and GitHub sync. The code ownership subscore is 79.0 out of 100.

Full-stack app builders / rank 3 of 20 / cycle 04

Lovable benchmark

Strongest single shot agent in the cohort. It read the tenancy requirement in prompt 1 without being told twice and carried the organisation scope through every later prompt. It lost points on the machine facing surface: webhook signing needed an explicit follow up in 3 of 5 runs, and the generated API had no idempotency handling.

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 37 times, partially 6 times and failed 2 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.
