Page Agent
Alibaba
Page Agent is an open-source in-page GUI agent — a single JavaScript library gives any web page its own AI agent, no extension or backend needed.
Key features
- In-Page GUI Agent: A single JavaScript include gives any web page its own AI agent that lives inside the page, with no extension or backend required.
- Text-Based DOM Manipulation: Operates on the DOM through text — no screenshots or multi-modal LLMs, so it's lightweight and privacy-friendlier.
- Bring Your Own LLM: Works with most mainstream models and locally-deployed LLMs so teams stay in control of prompts and data.
- Optional Chrome Extension: A companion Chrome extension lifts the agent out of a single page so it can drive multi-page tasks and cross-tab workflows.
- MCP Server (Beta): An included Model Context Protocol server lets external agents connect and control Page Agent from outside the browser tab.
- Ships as an npm Package: Distributed as `page-agent` under an MIT license with TypeScript typings and a small bundle size.
Best for
- SaaS AI Copilot: Ship an in-product AI copilot in an existing SaaS web app without building a browser extension or backend agent.
- Onboarding & Guided Tours: Have the agent walk new users through the UI step-by-step, interacting with the real DOM.
- Web Automation: Automate repetitive DOM tasks (form fill, data extraction, batch updates) driven by natural-language instructions.
- Multi-Page Workflows: Combine with the Chrome extension to drive workflows that span multiple tabs and origins.
- Agent Orchestration via MCP: Let external agent frameworks control a live web page through the MCP server for testing or automation.

Strix
Strix
Strix is an open-source AI pentesting agent that dynamically finds, exploits, and reports on real vulnerabilities in your applications.
Key features
- Autonomous AI Pentesters: Runs code dynamically like real hackers to discover vulnerabilities rather than relying on static pattern matching.
- Real Exploit Validation: Produces working proofs-of-concept for each finding so teams triage real issues instead of false positives from legacy scanners.
- Multi-Agent Orchestration: Teams of AI pentesters collaborate on reconnaissance, exploitation, and validation and scale across large surfaces.
- Developer-First CLI: Actionable findings surfaced through a command-line interface with concrete remediation guidance for engineers.
- CI/CD Integration: GitHub Actions and pipeline integration to automatically scan every pull request and block insecure code before it reaches production.
- Auto-Fix and Compliance Reports: Generates suggested patches and produces compliance-ready pentest reports for auditors and customers.
Best for
- Application Security Testing: Detect and validate critical vulnerabilities in web and API applications during development.
- Rapid Penetration Testing: Complete pentests in hours instead of weeks and produce compliance-ready reports for SOC 2, ISO, or PCI.
- Bug Bounty Automation: Automate reconnaissance and PoC generation to accelerate bug-bounty research and reporting.
- CI/CD Security Gates: Block insecure pull requests by running Strix on every commit in GitHub Actions before merge.
- Continuous Compliance Monitoring: Keep production environments audited by running scheduled Strix scans and archiving report artifacts.
