ProofHound vs TextGrad
Both stand on ai prompt generators. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APISelf-hostedWeb
Choose ProofHound for LLM classification workflows that need prompt iteration, auditable experiments, and controlled deployment. The free plan has tight project, member, and upload limits; the Pro plan is planned but checkout is not open.

TextGrad provides a PyTorch-like way to optimize text and other objects using LLM feedback. Its provider keys, experimental engine, and deployment options are important practical considerations.

ProofHound: what it does well
- Accepts CSV, TSV, JSONL, JSON array, and ZIP datasets.
- Targets overall accuracy or category-specific recall and precision.
- Keeps immutable prompt versions and experiment records.
- Supports A/B testing, staged releases, full rollout, and rollback.
- Offers self-hosting and private data storage on user infrastructure.
What to know first
- The free plan is limited to three projects and one member.
- Free plan dataset uploads are capped at 200MB each.
- The Pro checkout is not open yet.
- Users bring their own model provider.
TextGrad: what it does well
