About StyloBot

Bot protection you can run yourself.

StyloBot helps you stop unwanted traffic without sending your request data to someone else's service. Install it, use the defaults, and get on with running your site.

Where the name comes from

William Gibson described black ice as "king hell ice, black as the grave and slick as glass. Fry your brain soon as look at you." That's what most bot defenses feel like to legitimate users: invisible, hostile, and happy to fire first.

StyloBot is named after Stylo, the dog. He is large, determined, and always gets in the way. The product follows the same idea: stop bad traffic while letting real people through.

Fuzzy ice. Gets in the way. Never hurts.

Built for real sites

StyloBot is built by mostlylucid limited, a software company with more than 30 years of experience building products and engineering teams across Europe and North America.

It works with .NET and can run beside any web application. You do not need to change how your site works to add protection.

The product includes a deep set of detection checks and controls for teams that need them. You can review decisions, tailor policies, and manage larger deployments when you are ready. None of that is required to get started.

The open-source core is AGPL-3.0 licensed and does not send telemetry or callbacks. It is designed to start up, protect one site, and stay out of your way. Paid plans add live configuration, detailed dashboards, shared access, reporting, fleet management, compliance tools, and support.

What StyloBot stands for

Your data stays yours
Run StyloBot in your own infrastructure. Your traffic data does not become a vendor training feed.
Observe before you block
Start by watching traffic. Turn on blocking when the settings are right for your site.
Never punish real users
Protection should stop bots without making real visitors jump through hoops.
A useful free edition
The open-source edition works quietly in the background. Paid plans add live control, reporting, and shared access when your team needs them.
