What is Revalvo?
Revalvo is a local-first workbench for writing, running, versioning, and evaluating prompts across multiple AI models in parallel. It compares model outputs side-by-side with real-time scoring and maintains full version history with diffs, all without sending data to external servers.
Revalvo pricing
Pricing model: Freemium
Free to use; you only pay for API calls to model providers (e.g., OpenAI, Anthropic, Groq, OpenRouter)
Revalvo pros
- Local-first privacy: API keys stored in browser IndexedDB only, no hosted database or servers
- Parallel multi-model comparison: Run same prompt against 12+ providers simultaneously and see results side-by-side
- Git-style version control: Full immutable version history with diffs and rollback for prompts
- Supports local-only inference: Works with Ollama and LM Studio for completely offline operation
- No signup required: Bring your own API keys, no Revalvo account or markup
Revalvo cons
- Browser-dependent: Requires modern browser with IndexedDB; no mobile app or desktop client
- Reliant on user API keys: No built-in free credits; costs depend entirely on provider pricing
- Limited evaluator options: Only 40 pre-built evaluators available; custom scoring requires external setup
- Browser local storage limits: Large batch evaluations may be constrained by IndexedDB quotas
Frequently asked questions about Revalvo
Do I need a Revalvo account?
No. Revalvo is local-first—just paste your API keys into your browser and start running prompts. No signup required.
Where are my API keys stored?
API keys are stored in IndexedDB (browser storage) only. Revalvo never stores them on servers.
Can I use Revalvo completely offline?
Yes. Use local runtimes like Ollama or LM Studio to run models locally without sending data anywhere.
How many models can I compare at once?
You can run the same prompt against any combination of the 12+ supported providers in parallel.
Does it track costs?
Yes. Every result shows latency, token count, and cost per API call to the provider.
