Control which AI crawlers
access your applications.

Scalix Shield identifies the AI crawlers and bots reaching your deployed applications and lets you allow, block, or rate-limit each one — per crawler, per category, or with custom rules. Enforced at the gateway, with no code changes required.

49 known crawlers

Built-in database of 43 AI crawlers and 6 search engines across 6 categories, maintained from operators’ published documentation.

Allow / block / rate-limit

Set a policy per crawler or per category. Rate limits are enforced per minute at the gateway.

IP verification

Crawler identities are validated against operator-published IP ranges, refreshed automatically — spoofed user-agents are detected.

Generated robots.txt

Your policies compile to a robots.txt you can serve, so compliant crawlers see your rules before requesting a page.

Live visibility

See who's reading your site.

Shield identifies every crawler that touches your applications and judges it against your policy in real time. Identities are verified against operator-published IP ranges — a spoofed user-agent doesn't get Googlebot's privileges.

Allowed — passes through, logged
Rate-limited — held to your per-minute budget
Blocked — including impostors that fail IP verification

Set a policy. Ship a robots.txt.

Choose what each crawler may do. Shield enforces the decision at the gateway in real time and compiles your policy into a robots.txt that compliant crawlers read before requesting a page.

Interactive demo — your real policies are managed in the console, per project.

Six crawler categories

Search engines

Googlebot, Bingbot, Applebot and others — typically allowed to preserve search visibility.

AI assistants

Crawlers that fetch pages in response to a user’s question, such as ChatGPT-User and PerplexityBot.

AI coding agents

Agents that read documentation and repositories while writing code.

AI training scrapers

Crawlers that collect content for model training. Allow, block, or rate-limit each one.

AI data providers

Companies that resell crawled content as datasets.

AI agents

Autonomous agents acting on a user’s behalf.

Custom rules and full visibility

Define your own user-agent rules for crawlers not yet in the database — they take precedence over built-in policies. Every decision is logged: which crawlers reached you, how often, and the action Shield took — in the console or via the API.
