Is Revalvo right for you?
A good fit for
Useful for developers comparing prompt versions on representative cases before shipping them.
Before you choose
Prompt data and keys are stored in browser IndexedDB according to the vendor, but remote providers receive requests; OpenAI/Anthropic connections use an in-memory CORS proxy. Fully offline use requires a local runtime. GitHub sync needs a scoped token. Forty evaluator options and HTML/Markdown/JSON/CSV reports are advertised. Example pass rates are demos, not independent tests; a score is not proof of correctness.
Workflow and handoff
Use a non-sensitive representative dataset, compare outputs and scoring rules and inspect provider/proxy handling and report evidence before release.
