OWASP Bug Logging Tool


OWASP BLT (Bug Logging Tool) is a powerful tool designed to allow everyone who uses the internet to help improve it. With BLT, users can submit any type of issue they encounter, whether it’s a simple design flaw like a button being the wrong color, or a serious security vulnerability. By following responsible disclosure ethics, BLT helps to ensure that reported issues are addressed in a timely and appropriate manner.

One unique feature of BLT is that it rewards users for reporting bugs. As users report more issues, they earn more points, which can be verified for extra points. Additionally, companies and organizations can get involved with BLT and launch their own bughunt programs with prize pools. This not only incentivizes users to report bugs but also encourages companies to actively seek out and address vulnerabilities before they can be exploited.

Overall, OWASP BLT is an important tool for improving internet security and promoting responsible disclosure practices. By allowing anyone to report issues, rewarding users for their contributions, and providing a platform for companies to launch bughunt programs, BLT empowers individuals and organizations to work together towards a safer and more secure online environment.


The OWASP Bug Logging Tool Project is a community-driven initiative that relies on the contributions of volunteers from all over the world. These dedicated individuals generously donate their time and expertise to help improve the security of the internet for everyone.

We understand that without the invaluable contributions of our volunteers, the OWASP BLT Project would not be possible. Therefore, we would like to express our sincere gratitude to all the contributors and supporters who have helped make this project a success.

We are proud of the diverse and dedicated community that has grown around this project. We recognize that each contributor brings their unique perspective, skills, and experiences to the table, and we value each and every one of them.

At OWASP, we strive to foster a welcoming and inclusive environment where everyone can contribute and thrive. We believe that diversity is essential to the success of the OWASP BLT Project, and we are committed to providing a safe and supportive space for all our volunteers.

Once again, we would like to extend our heartfelt thanks to all the contributors and supporters of the OWASP Bug Logging Tool Project. Your efforts are truly appreciated, and we look forward to continuing our work together to make the internet a safer place for everyone.




How it Works

OWASP BLT is a bug logging tool that allows users to report issues and get points, and companies are held accountable. Testers can win money through company-sponsored Bug Hunts, tips, or the Grand Prize/Jackpot. Organizations can keep their customers happy by giving them a consistent bug-free user experience.

Build Status


This is a call for contributions to a project called BLT. The project has a list of issues that are tagged as “good first issue” to help new contributors get started. There are also guidelines for contributing to the project. If you find a bug or have an improvement, you can report it using BLT. To make sure your contribution is linked to the relevant issue, create a new branch with the button on the right of the issue to create a new branch. Additionally, if you want to take ownership of an issue, you can use the comment “assign to me” or /assign to assign it to yourself. Contributing to the project is appreciated and benefits both the project and the contributor. Contributions are always welcome and appreciated!

  12. How to use ChatGPT to contribute to the project ?
    OpenAI’s ChatGPT can be a helpful tool when it comes to assisting with projects like OWASP’s bug logging tool. As a large language model trained on a variety of sources, it can generate human-like text based on the inputs provided to it. You can use it to facilitate many parts of your development process, including but not limited to troubleshooting, code generation, documentation writing, and testing. Here’s a detailed way to approach this:

    1. Development Phase:
      • Code Reviews and Troubleshooting: ChatGPT can provide advice on code optimization, best practices, and debugging. You can ask it for input on your Django, Flutter, JavaScript code, or any other language’s code.
      • Code Generation: For quick prototyping or generating boilerplate code, you can ask ChatGPT to generate snippets. For example, you might need a quick Django model or a Flutter widget.
      • Documentation: Writing documentation can be time-consuming. ChatGPT can help by generating documentation based on your code and requirements. You simply need to provide a clear description of what the function or component does, and ChatGPT can help generate an appropriate documentation comment.
    2. Testing Phase:
      • Generating Test Cases: You can ask ChatGPT to help you brainstorm and generate various test cases to ensure your code works as expected under different circumstances.
      • Writing Test Scripts: Similar to code generation, you can ask ChatGPT to help you write test scripts. Provide a clear description of the test, and it can generate a basic test script for you.
    3. User Support:
      • User Queries: You can integrate ChatGPT as a part of your support team to respond to user queries. You would need to train it on your specific product using Reinforcement Learning from Human Feedback (RLHF) so it can answer queries accurately and contextually.
    4. Project Management:
      • Generating Reports: You can ask ChatGPT to help you generate progress reports, or any other text-based reports. Provide it with the necessary data, and a brief about what the report needs to convey.
      • Communication: You can use ChatGPT to help draft project updates, emails, or any other communications you might have with stakeholders.
    5. GitHub Action:
      • Automating Tasks: ChatGPT could be used in a GitHub Action to automate various tasks. For example, it could be used to automatically generate release notes based on merged PRs, or to check for specific code style in PRs.
    6. Browser Extension:
      • User Interface: You can use ChatGPT to assist users on the extension. For example, you might use it to help users navigate the extension or troubleshoot problems. It could also be used to generate helpful suggestions or tips based on the context of the user’s current webpage.

Remember that GPT-4, like all AI models, is a tool that can help assist in various tasks, but it won’t replace human judgment and expertise. Always review and consider the suggestions it provides, and don’t use it for sensitive tasks without appropriate checks in place.

Remember to comply with OpenAI’s use case policy and ensure that the usage of ChatGPT is ethical, privacy-preserving, and secure.
