- Embed a digital employee that runs long-running tasks inside your SaaS
- Build model evaluation, legal, ops, or planning agents backed by frontier coding models
- Add an AI feature that produces videos, games, docs, or codebases as artifacts for end users
- Skip building sandboxing, streaming, retries, and permissions in-house
- Give internal teams a governed way to run Codex or Claude Code against production data
- Deploy an agent backend with production credits and hard cost caps
Known Agents
Known Agents
Analytics and control platform to track, control, and monetize AI agents, crawlers, and bots visiting your website.
Key features
- Real-time Agent Tracking: Identifies and logs every crawler, scraper, and AI agent visiting your site with timestamps, user-agent analysis, and source classification so teams can monitor agent-driven traffic as it happens.
- LLM Referral Attribution: Tracks when content served from your site is referenced by LLMs and assistant platforms, enabling measurement of downstream referrals and visibility into which pages are surfaced by agents.
- Automatic robots.txt & Response Control: Generates and manages robots.txt rules and dynamic response behaviors to allow, block, or tailor content served to specific agents or crawlers without manual server changes.
- SDKs and Integrations: Provides an official Node.js SDK (and other integrations) to embed tracking, referral reporting, and control hooks into websites, servers, and CMS platforms for automated instrumentation.
- Agent Profiling & Analytics Dashboard: Aggregates agent visits into dashboards and reports that show agent types, frequency, pages accessed, geographic distribution, and trends to inform content and security decisions.
- Monetization & Growth Tools: Surfaces opportunities to convert agent traffic into growth by identifying pages frequently referenced by assistants and enabling referral tracking and attribution for business metrics.
- Blocking and Protection Controls: Allows operators to detect scraping behavior and enforce blocks or mitigations selectively for malicious crawlers while permitting beneficial agents.
- Real-time tracking of crawlers, scrapers, and AI agents
- Identification via User-Agent strings and additional request signals
- LLM referral tracking (identify referrals from LLM assistants)
- Automatic robots.txt generation and management
- Scraper blocking and access-control policies
- Official Node.js SDK (available on GitHub) for easy integration
- WordPress plugin compatibility / integrations for CMS sites
- Traffic analytics and reporting geared toward agent traffic
- GitHub-hosted SDK and developer resources
Best for
- Publisher Monetization: Identify which articles and pages are frequently referenced by LLMs or assistants, attribute downstream traffic, and prioritize content or referral flows to capture new visitors or revenue.
- Security and Anti-Scraping: Detect, profile, and selectively block scraping agents or abusive crawlers in real time while preserving access for legitimate assistants and search bots.
- Content Optimization for Assistants: Analyze which pages are surfaced by AI agents and optimize structured data, copy, and canonical signals to improve how LLMs and assistants use site content.
- LLM Referral Tracking: Instrument server-side SDKs to capture referral metadata when external assistants cite or link to your content, enabling measurement of agent-driven conversions.
- CMS/Platform Integration: Embed Known Agents via SDK or plugin (e.g., for WordPress) to get immediate visibility into bot and agent behavior without custom engineering work.
- Operational Monitoring: Use agent activity dashboards to detect sudden spikes in crawler traffic, diagnose indexing or scraping incidents, and adjust rules or capacity accordingly.
- Detect and block content scrapers and abusive crawlers
- Track which LLMs and assistants refer traffic to your site
- Optimize and configure site behavior specifically for AI agents
- Monetize agent-driven referral traffic and measure impact
- Automatically generate and serve robots.txt tailored to agent types
- Integrate agent analytics into web applications via Node.js SDK
