HUMANIZER

Moves like a human. Not a bot

Curved trajectories. Bézier paths with natural drift, never point-to-point jumps.

Variable velocity. Speeds up through the middle and slows into the target, the way Fitts’s law predicts a real hand.

Overshoot and settle. Lands slightly past the target, then corrects, like a real pointer.

Real event streams. Genuine coalesced pointer events, human typing cadence, and natural scroll, not teleported inputs.

Solari humanizes cursor movement with curved paths, variable speeds, natural acceleration, and subtle overshoot. This helps bypass bot detectors and lets agents navigate websites more like a real person.

FEATURES

Browsers, built for agents

Stay signed in

Cookies, storage, and logins persist across sessions.

Replay every session

Review every browser action with shareable recordings.

Smart proxy

Built-in residential proxies with rotating IPs and session geolocation.

Works with your stack

Connect through Playwright, Puppeteer, Selenium, or raw CDP. No rewrite.

Persistent Browser State

Cookies, storage, and session state persist across runs.

Move files seamlessly

Upload files and retrieve downloads directly from browser sessions.

Step in instantly

Watch sessions live, take control, then hand them back.

Scale without limits

Launch hundreds of warm browser sessions simultaneously.

TWO WAYS TO RUN

Run faster. Debug smarter

Headless

Run faster

Execute browser tasks without rendering a visible interface. Lower overhead and faster throughput for automated workloads.

Headful

See and take control

Stream the browser live, watch each action, and step in whenever human input is needed.

ANTI-BOT

Bypass the web’s toughest bot detection

Cloudflare
BOT MANAGEMENT & TURNSTILE
Cleared. Scores every request with machine learning trained on Cloudflare’s global network, plus TLS and HTTP fingerprinting and behavioral heuristics. Turnstile replaces the CAPTCHA with an invisible browser challenge.
DataDome
BOT & ONLINE FRAUD PROTECTION
Cleared. Runs every request through an AI engine in real time, weighing thousands of client-side and server-side signals to determine whether traffic is automated or human.
HUMAN
BOT DEFENDER (PERIMETERX)
Cleared. Uses behavior-based detection to model how real people move, click, and type, backed by interactive challenges that distinguish humans from automation.
Akamai
BOT MANAGER
Cleared. Grades traffic at the edge using browser fingerprinting, behavioral anomaly detection, and JavaScript telemetry collected while the page runs.
Google
RECAPTCHA
Cleared. Assigns a risk score from on-page behavior. v3 scores silently with no prompt, while v2 can fall back to checkbox and image challenges.
