Best Free Bug Bounty Platforms of 2025

We are a web3 bug bounty platform since 2017. We help to set a clear scope (or you can do it by yourself), agree on a budget for valid bugs (platform subscription is free), and make recommendations based on your company`s needs. We launch your program and reach out to our committed crowd of hackers, attracting top talent to your bounty program with consistent and coordinated attention. Our community of hackers starts searching for vulnerabilities. Vulnerabilities are submitted and managed via our Coordination platform. Reports are reviewed and triaged by the HackenProof team (or by yourself), and then passed on to your security team for fixing. Our bug bounty platform allows you to get continuous information (ongoing security for your app) on the condition of security of your company. Independent security researchers can also report any breaches found in a legal manner.

The Open Bug Bounty initiative provides a platform for website owners to receive insights and assistance from security experts worldwide in a manner that is transparent, equitable, and organized, ultimately enhancing the security of web applications for the collective good. This platform facilitates coordinated vulnerability disclosures, allowing any legitimate security researcher to report vulnerabilities on various websites, provided the findings are obtained without using invasive testing methods and adhere to responsible disclosure practices. Open Bug Bounty's involvement is strictly to verify the reported vulnerabilities independently and to ensure that website owners are informed through all available channels. After the notification process, the website owner and the researcher can communicate directly to address the vulnerability and manage its disclosure effectively. At all stages of this process, we do not serve as a middleman between the website owners and the researchers, fostering a direct line of communication to promote a smoother resolution. This approach ultimately enhances trust within the cybersecurity community, encouraging more researchers to participate in improving web application security.
