What is open·kritt?

Pointing a model at an entire repository and asking it to find vulnerabilities rarely works well. open·kritt takes a focused approach: break the research into small, well-defined tasks, run them across AI agents in parallel, and combine their output into findings you can validate and prioritize.

It is built for security researchers and security-minded developers who want control over their prompts, workflows, model providers, and infrastructure.

What it does

• Build workflows — chain focused prompts into reusable security research playbooks.
• Run scans — analyze remote or local repositories and their dependencies with Codex, Claude Code, or Grok Build.
• Verify findings — use post-scripts to validate issues, build proofs of concept, and produce reports.
• Export scan results — package canonical findings, structured data, post-processing output, reports, and proofs of concept in one ZIP archive with a share-safe manifest; completed scans produce complete exports, while stopped or failed scans with findings produce clearly marked partial exports. Attacker-influenced report and PoC source is kept as plain text.
• Prioritize results — apply custom severity rankers, a consistent finding schema, and automatic de-duplication.
• Bring your own model access — use a Codex login or connect through OpenAI, Anthropic, DeepSeek, OpenRouter, or xAI.

Built from real security research. The Kritt team has earned over $1,500,000 in bug-bounty payouts under the researcher name Blockian (Immunefi · HackenProof · blockian.xyz · @Kritt_AI). open·kritt is the open-source distillation of the internal project behind that work.

Getting started

You need Git, Docker with Docker Compose, and Node.js 20 or newer. The repository-local CLI has no install step.

git clone https://github.com/Kritt-ai/open-kritt
cd open-kritt
./kritt setup
./kritt start

Open http://localhost:5173 once the stack is running. You only need one model-access option; ./kritt setup guides you through the available logins and API keys. A GITHUB_TOKEN is optional and only needed for private GitHub repositories.

On a server without a browser or desktop, leave the stack running and open another shell:

./kritt-headless

The headless CLI imports portable workflow, post-script, skill, and ranker JSON; creates scans with the same backend validation as the web form; displays scan status, stages, and failure reasons; edits non-secret runtime settings; and exports finding bundles. It does not display finding contents in the terminal. See the headless CLI guide.

The default ports bind to 127.0.0.1, and the backend does not include application authentication. Keep the stack private.

Tool-enabled agents run as root inside disposable job containers, with writable repository copies and direct internet access so they can install tools, compile targets, run tests, and build proofs of concept. Run open·kritt on a dedicated Docker host or VM; see the threat model before scanning untrusted code.

For prerequisites, manual Docker setup, and provider-specific instructions, read the installation guide and AI provider setup.

In Accounts, use the persisted Active switch to choose which accounts may receive new assignments while keeping other credentials saved. See active provider accounts.
