| content.faq | - | `[{"answer":"An open-source Python framework that scans smart contract source code for security issues using built-in detectors, generates visual contract analysis reports, and provides an extensible API for writing custom vulnerability checks. Enables developers to catch bugs before deployment and better understand contract behavior. It is indexed under Blockchain Dev Tools.","source":"https://github.com/pricing","question":"What is Slither?","confidence":0.6},{"answer":"Slither supports a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://github.com/pricing","question":"What platforms does Slither support?","confidence":0.6},{"answer":"Yes. Slither can be deployed cloud / SaaS and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://github.com/pricing","question":"Can Slither be self-hosted?","confidence":0.6},{"answer":"We have confirmed 9 integrations for Slither, including GitHub Actions, Hardhat, Foundry, Brownie, Dapp, Pre-commit, Docker and Pyth Oracle detectors, plus 1 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://github.com/pricing","question":"What does Slither integrate with?","confidence":0.6},{"answer":"Yes. Slither is published under the AGPL-3.0 licence, a copyleft licence, so check its terms before embedding it in a closed-source product. Licence terms can change between releases, so verify against the repository for the version you intend to use.","source":"https://github.com/crytic/slither","question":"Is Slither open source?","confidence":0.95}]` |
