In 2026, browsing the web is an agent's job. Google now lets Chrome browse and fill in forms on a person's behalf, and every team building its own agents needs cloud browsers that start fast, stay signed in and scale with the fleet.
Hyperbrowser sells browsers, sandboxes, web data APIs and agents from one credit balance, and teams look elsewhere when concurrency, stealth or the flat browser rate stop fitting. The strongest alternatives are Solari, Browserbase, Steel, Kernel and Anchor Browser, and Solari leads for teams that bring their own agent: it starts sessions faster on an open benchmark and runs browsers, sandboxes and desktops from one account. This guide covers why teams move, what to check, and what each vendor costs.
Why Do Teams Look for a Hyperbrowser Alternative?
Teams usually start looking when the fleet outgrows a plan ceiling, a protected site needs stronger stealth, or the bill grows faster than the work. Hyperbrowser says its Startup plan is $30 a month with 25 concurrent sessions, its Scale plan is $100 a month with 100, Enterprise starts at 1,000+ concurrent sessions and browsers cost $0.10 per hour on every self-serve plan, on Hyperbrowser's pricing page.
Above the Scale plan, the next step is a sales contract. Hyperbrowser also keeps ultra stealth mode for Enterprise, which matters the day a target site starts blocking basic stealth.
The flat rate is the third reason. A bigger Hyperbrowser plan buys more capacity, not a lower price per browser hour.
What Should You Look for in a Hyperbrowser Alternative?
The right alternative fixes the limit that started the search without adding a new one. Check these five things:
Session start time. An agent that opens a fresh browser per task waits for it on every task. Compare vendors on the same benchmark run, not on each vendor's own numbers.
Concurrency without a contract. Check how many browsers run at once on a self-serve plan. A fleet that doubles next quarter should not need a sales call to keep running.
Stealth, proxies and CAPTCHA solving. Find the plan where each one starts, because a stealth feature on the top tier sets the real price of a protected site.
Logins that survive between runs. Your agent should sign in once and reopen the same cookies next time. Signing in on every run costs time and trips security checks.
Code and screens on the same account. Many agents also run generated code or operate desktop apps. One account removes a second vendor, a second key and a second bill.
The Alternatives at a Glance
1. Solari
Solari is the environment an agent runs in: you bring the model and the logic, and Solari supplies the browser, the machine and the screen. Here is what Solari does for a team moving off Hyperbrowser:
Solari starts sessions in milliseconds. On Steel's open-source benchmark, across 5,000 runs with Solari's results in a pull request that is still open, Solari averaged 199.9 ms end to end with session create at 8 ms, about 4.5x faster than Steel, about 4x faster than Kernel, about 14.8x faster than Browserbase and about 40x faster than Anchor. An agent that opens a session per task gets that time back on every task.
Solari runs a whole fleet at once. With Solari you can launch up to 100,000 browser sessions at once, so your agent works through a full list in one pass. Solari's Professional plan is $200 a month with 150 concurrent browsers and sessions up to 24 hours.
Solari keeps your agent signed in. A Solari profile saves your login, cookies and site data, so every later session opens already signed in. Profiles use Playwright's storage state format, and Solari browsers work with Playwright and Puppeteer, so your existing scripts and logins move over as they are.
Solari gets through sites that block automation. Turn on stealth, route traffic through a residential, static or mobile proxy, and Solari solves the CAPTCHA in the background. Stealth starts on Solari's Starter plan at $20 a month with 10 concurrent stealth sessions, so a protected site does not need a contract.
Solari costs less per hour. Solari bills $0.07 per browser hour on Professional and $0.05 on Team, with no end-of-month overage charge, so a growing fleet pays a lower rate instead of a bigger flat one.
Browsers are only part of the job. Solari sandboxes run agent-generated code with commands, files, snapshot and fork, at $0.0245 per vCPU-hour on Professional. For computer-use models, Solari desktops add a full Linux computer with a screen your agent can operate, and every session can be recorded and replayed for review.
Where it fits. Hyperbrowser is the more established vendor with the broader product catalogue; Solari is the younger company and moves faster on speed and price. Solari is best for teams that run their own agent and want fast sessions, saved logins and code execution on one bill.
2. Browserbase
Browserbase is the incumbent of the category, and it suits teams that want search and fetch beside the browser.
Pricing and plans. Browserbase says its Developer plan is $20 a month with 25 concurrent browsers and 100 browser hours, then $0.12 per browser hour, and its Startup plan is $99 a month with 100 concurrent browsers and 500 browser hours, on Browserbase's pricing page; at list price, Solari is about 2x cheaper per browser hour. A team inside the included hours pays a flat fee, and overage is where the bill grows.
Where it shines. Browserbase includes search and fetch calls on every plan. A team that chose Hyperbrowser for its web data APIs keeps that breadth.
Trade-off. Browserbase's Free plan caps session length and leaves out CAPTCHA solving. If stealth started your search, check where solving begins on the plan you would buy.
3. Steel
Steel is an open-source browser API for agents, and it fits teams that want the option to run the browser themselves.
Pricing and plans. Steel says its Scale plan is $250 a month plus usage, with 100 concurrent sessions, sessions up to 1 hour and browsers at $0.08 per hour, on Steel's pricing page; at list price, Solari is about 1.6x cheaper per browser hour. Steel's rate sits below Hyperbrowser's once a team commits to the fee.
Where it shines. Steel Browser is open source and can be self-hosted. A team with data-residency rules can keep the browser inside its own network.
Trade-off. Steel keeps its stealth browser and its longest sessions for Enterprise. Teams leaving Hyperbrowser over stealth meet a similar contract step.
4. Kernel
Kernel is browser infrastructure for agents with managed logins, and its billing rewards agents that sit idle between steps.
Pricing and plans. Kernel says its free Developer plan comes with $5 a month in credits, its headless browsers bill at $0.0000166667 per second of active runtime, and a browser enters standby 5 seconds after its last CDP or Live View activity and stops accruing usage, on Kernel's pricing docs. Kernel publishes no hourly price, so a team compares it by running a sample workload.
Where it shines. An agent waiting on a model pays for the time it works, not the time it thinks. Agents with long pauses between steps benefit most.
Trade-off. Billing by the second is precise but harder to forecast than an hourly rate. Kernel also keeps HIPAA for Enterprise.
5. Anchor Browser
Anchor Browser bills by completed task rather than by browser hour, and it leans on logged-in sessions.
Pricing and plans. Anchor says its Starter plan is $50 a month with 50 credits and up to 25 concurrent browsers, overage is $1.00 per credit, each completed task costs 0.1 credits and its full stealth solution starts on the Growth plan at $2,000 a month, on Anchor's site. Anchor does not define a credit further.
Where it shines. Logged-in browsers and automated CAPTCHA bypass start on Starter, and Enterprise adds bring-your-own-cloud or on-premise deployment. A team with strict hosting rules can run Anchor inside its own cloud.
Trade-off. Task-based credits are hard to set against an hourly rate, so an estimate needs a sample workload. Full stealth also sits several tiers up.
Where Are Browser Agents Going Next?
Over the next year, browser agents move from side projects to daily production work:
Fleets run all day. Agents run on schedules and triggers, so concurrency and start time decide how much work gets done.
Sites answer agents. More sites check for automation, so stealth, proxies and saved logins become part of every session.
Agents leave the browser. Models with computer use already operate whole desktops, so one agent needs a browser, a sandbox and a screen.
Bills follow the work. Hourly rates keep falling as fleets grow.
What stays human is judgment: which sites an agent may touch, what it submits under your name, and which vendor sits in the critical path.
Which Hyperbrowser Alternative Should You Choose?
Choose Browserbase for search beside browsers, Steel for a self-hostable browser, Kernel for agents that idle between steps and Anchor Browser for billing per task. Stay with Hyperbrowser when its web data APIs and hosted agents are why your team signed up. Choose Solari when session speed, a lower browser rate and stealth without a sales call decide the budget, or when your agent also needs sandboxes or desktops.
