AI agents need secure environments that scale

Every task needs an isolated place to browse the web, run code, or operate software. As demand grows, those environments must start fast, stay contained, and run in parallel.

Solari gives them exactly that

Solari provides secure, isolated environments each agent can work in, from cloud browsers and sandboxes to desktops.

Designed for agents

Built for an agent, all through one API.

Engineered for speed

Browsers are ready in 8 ms and sandboxes in 90 ms, so your agents never wait on infrastructure.

Built for scale

Run one agent or a fleet of thousands in parallel, each in its own isolated environment.

PRODUCTS

One platform. Everything AI agents need to execute

Give every agent the environment it needs without stitching together separate infrastructure.

Cloud Browsers

For agents that need to browse, authenticate, scrape, and interact with the web.

Solutions by industry

One platform

Learn one client. You know all three

import { Solari } from "@solarisdk/browser"
 
const client = new Solari({ apiKey: process.env.SOLARI_API_KEY })
 
const browser = await client.launch({ stealth: true, proxy: "us", captcha: true })
// Drive it with Playwright or any CDP client

One API gives your agents access to browsers, sandboxes, and desktops. Use the same authentication, session management, and infrastructure across every environment. Start with one primitive today and and another as your agents grow.

FAQ

Before you deploy. Everything you need to know

Solari is the fastest infrastructure for AI agents. We offer stealthy headless browsers, full VMs, and isolated sandboxes. Our infra stack enables your agents to access every environment in one API.

A browser is best for agents that need to interact with websites, log in, scrape data, or automate web workflows. A sandbox is ideal for safely running code, scripts, and tools in an isolated environment. A VM is better for workloads that need a full operating system, persistent desktop, custom software, or deeper system-level control.

Yes. Team and Enterprise customers can deploy Solari within their own VPC for greater control over infrastructure, networking, and security. Contact our team to discuss private deployment requirements.

Yes. Idle machines pause automatically instead of shutting down, allowing you save states. The machine stops counting against your plan, and it picks up right where it left off on the next connect. Any running machine can also be snapshotted, rewound, or forked into independent parallel copies from one prepared starting point.

We support TypeScript, Python, Go, Rust, and C++.

Stealth mode makes the browser behave more like a real person. Residential proxies route traffic through real home networks in the country you choose. reCAPTCHA, hCaptcha, and Turnstile are handled automatically. Persistent profiles keep logins, cookies, and site data across sessions, so agents can start already signed in.

Solari sandboxes execute untrusted, AI-generated code on hardware-isolated microVMs, fully separated from your systems.

Yes. You can create a custom template with the image builder by picking a base OS, adding apt and pip packages, running your own setup commands, and setting environment variables. You can also snapshot a machine you set up by hand. Any machine launched from that template starts in about a second with your tools already in place.
