Crashmire or Giskard: which one to choose?
Giskard is a French red-teaming and evaluation platform for AI agents, with an open-source library and a platform for teams. Crashmire is a service: we crash-test your agent and deliver the report.
| Giskard | Crashmire | |
|---|---|---|
| What is tested | Security and answer quality: attacks, jailbreaks, hallucinations, regression tests. | Your agent's behaviour as it is (prompt, tools, rules) when its target is out of reach or someone tries to trick it: does it cross a line? |
| How it works | A Python library and a platform (Hub) your teams use to design and run their tests, with CI integration. | A service: you describe the agent, we replay it on several models and several runs. No access to your systems, nothing to install. |
| Who it is for | Technical and data teams who want to tool their own continuous testing. | Executives, risk and compliance, CISOs, business teams deploying an agent; from SMBs to large organisations. |
| What you get | A tool and test results; the fixes are up to your teams. | A report for management: flaws with how they happened, tested fixes (before / after), mapping to the AI Act and OWASP, a re-test included. |
| Price | Free library; enterprise platform on quote. | Public prices: online from €490 excl. VAT for an SMB, €4,900 to €25,000 for a large organisation, continuous monitoring from €36,000 a year. |

And both together?
Yes: a tool like Giskard for your developers' daily tests, Crashmire for the independent opinion before a release and for the compliance file.
