Bruno
Bruno review on AInexfinder — freemium AI tool for Coding & Development. Features, pricing notes, and alternatives.
- True data locality and privacy
- Git-friendly versioning of API tests
- Free open-source core
- Git-native collections as plain-text files
- Lacks built-in cloud collaboration and monitoring
- Limited AI assistance versus AI-first tools
- Integrations may not cover every app in your stack
Promptfoo
Promptfoo generates custom attacks against your own AI applications to find vulnerabilities including prompt injections, jailbreaks, data leaks, business rule violations and insecure tool use. It covers red teaming, evaluations, code scanning, model security, guardrails and MCP, with an open-source core.
- Generates attacks for your specific application rather than checking a list
- Business rule violation testing addresses rules that exist only in a prompt
- Names insecure tool use, which is the risk that grows as agents can act
- Open source core makes a security tool inspectable rather than trusted
- Finds attacks it knows how to generate; novel techniques appear constantly
- Results describe the system as configured, and configurations change
- Cannot fix architecture — a dangerous permission needs removing, not filtering
