Harden AIF is a free, local security tool for AI coding agents. Its post-trained model checks tool calls before they run, using your request and session context. It beat frontier models on key agent-security benchmarks, while keeping your repo and tool output on your machine.














Very cool product. Just gave it a spin and I think this is gonna just stick to the part of tools I use! Good going team.
@himanshu_garg Love it! Thanks for the feedback, Himanshu. Our goal is to set and forget, so that it just keeps working around the clock without any babysitting needed from your side.
Very timely for managing critical safety of coding agents. Many congratulations on the launch 🚀🚀🚀
@parthpareek Thanks, Parth. Also, feel free to book a call if you face any issue. Our team will be more than happy to get things set up on your system. Harden is free for individual developers.
been waiting on the PH launch for a while
this seems awesome for companies now shipping AI code to also remain secure!
@arcinston Really appreciate that Arush, and we have been excited to get this out too. Harden is free for individual developers. You can just set it up right away using a single command, and it can just fit into your current workflow and existing AI coding agent that you're already using
Hey team! Congrats on the launch day. I like the supporting of multiple agents instead of concentrating on some one. More practical aaproach! Best of luck today!
@kate_ramakaieva Thank you, Kate. We started with the coding agents that are the most popular and are expanding coverage to more agents. If there are agents that you want us to cover, just drop a note here.
Congratulations on the launch @pushpak_pujari1 ! Excited to try out Harden finally.
@siddhartha_saxena2 Thank you! Would love your feedback. Once click install from https://harden.run/
@rukhsar_amjad Yes, definitely do try it. It is completely free, installs in seconds, and watches your agents 24/7 so that you don't have to.
Congrats on the launch!
@thisiskp_ Thanks a lot, KP! Really appreciate the support. Coming from someone who’s built so much in public and around developer communities, it means a lot 🙌
@thisiskp_ Thank you, KP. Your support means a lot.
