USE CASES

See what teams run on Solari

Web Scraping

Pull pricing, listings, company data, and market signals from live websites without maintaining brittle scraping infrastructure.

AmazonLinkedInGoogle

Browser Agents

Let agents navigate sites, fill forms, upload files, and complete multi-step browser workflows end to end.

SalesforceHubSpotStripe

E-Commerce Monitoring

Track prices, inventory, listings, and competitor changes continuously instead of checking marketplaces manually.

AmazonShopifyGoogle

Authenticated Workflows

Keep sessions signed in so agents can return to authenticated portals and continue work without logging in every run.

SalesforceHubSpotStripe

Lead Research

Find companies, collect prospect data, and enrich records automatically before leads enter your sales workflow.

LinkedInGoogleHubSpot

End-to-End Testing

Test signup, login, checkout, and account flows in real browser sessions before broken journeys reach customers.

Competitive Intelligence

Monitor competitor pricing, products, and site changes automatically instead of repeatedly checking pages by hand.

GoogleAmazonShopify

Portal Automation

Enter data, submit forms, and complete workflows inside portals that don't expose the APIs your agents need.

SalesforceHubSpotStripe

High-Volume Operations

Run browser sessions in parallel so large automation workloads finish faster without manually managing each session.

AmazonLinkedInGoogle

Code Interpreter

Execute generated code and return files, charts, tables, or structured output without provisioning infrastructure for each task.

AI Evaluations

Run identical agent tasks in reproducible environments to compare models, prompts, and agent behavior reliably.

PythonDockerGitHub

Reinforcement Learning

Launch, reset, and fork training environments in parallel to scale agent rollouts without manually managing compute.

PyTorchPythonLinux

Data Analysis

Load datasets, run analysis, and generate charts or artifacts so agents can finish analytical workflows end to end.

Parallel Execution

Split large workloads across multiple environments so independent jobs execute simultaneously instead of sequentially.

DockerLinuxGitHub

Long-Running Jobs

Keep processes alive for tasks that take minutes or hours without forcing agents to restart their work.

LinuxPythonNode.js

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.
