In 2026, software for AI agents is sold by the unit of work, not by the seat. Agents run without a person behind each login, so vendors meter the steps, minutes and hours they use, and usage- and outcome-based pricing is replacing seat licences. The unit a vendor picks decides how your bill grows when an agent goes from ten runs to ten thousand.
Solari and TinyFish pick different units. Solari charges for each hour a browser, sandbox or desktop runs, drawn from one balance that covers all three, and you bring your own model. TinyFish charges per agent step, browser minute or monitor check, with the model, proxies and anti-bot handling folded into each price. This guide covers what each price buys and which fits your agents.
Why Is Agent Infrastructure Priced by Usage?
An agent's cost follows the work it does, not the size of the team. An agent fleet may open hundreds of headless browsers overnight and none in the afternoon, so a seat count says nothing about the bill.
A per-step price grows with how many actions a goal takes. A per-hour price grows with how long an environment stays open. The same job can produce two very different bills, so compare the unit before the rate.
What Do You Pay for on TinyFish?
TinyFish sells five metered products from a prepaid Wallet, with no subscription and no monthly minimum. TinyFish says TinyAgent costs $0.016 per step, TinyBrowser $0.002 per minute, or $0.12 per browser hour at list, and TinyMonitor $0.005 per check, with 2 concurrent runs for TinyAgent and 5 concurrent sessions for TinyBrowser on pay as you go.
TinyAgent, per step. Each run includes the model the agent reasons with, so there is no model provider bill on top. A site that needs more clicks costs more per result.
TinyBrowser, per minute. You control a remote browser over Playwright or CDP and bring the agent logic yourself. This is the product to set against a Solari browser.
TinyMonitor, per check. It watches a page or search topic on a schedule and alerts by email or webhook on a change. The schedule sets the bill, so a check every few minutes costs far more than one a day.
TinySearch and TinyFetch, free. TinyFish says both are free within rate limits. Heavy volume meets those limits before it meets a bill.
Proxies and anti-bot, included. TinyFish says paid runs include residential proxies, anti-bot handling and stored screenshots and logs. There is no separate line for a proxy, so a run on a public page pays for the same bundle as a run on a guarded one.
Enterprise, by contract. TinyFish says Enterprise sets rate limits and concurrency to your workload and adds SSO, audit logs and VPC deployment. Its price is not published.
What Does the Same Work Cost on Solari?
Solari charges per hour for each environment, and a browser hour costs less on each paid plan:
Solari's Free plan costs $0 a month with $3 of usage included each month, 3 concurrent browsers and browsers at $0.15 per hour. Starter costs $20 a month with $20 of usage included and runs 20 concurrent browsers at $0.10 per browser hour. Professional costs $200 a month with $200 of usage included and runs 150 concurrent browsers at $0.07 per browser hour.
Team is a custom contract at $0.05 per browser hour with 150+ concurrent browsers. Enterprise runs browsers at a tenth of Team's rate, and Solari supports up to 100,000 concurrent browsers on Enterprise, so you can run a whole target list at once.
Included usage refills each month and Solari never bills past your balance, so there is no end-of-month overage charge.
How Do Solari and TinyFish Pricing Compare?
Solari prices the environment and lets you add only what each session needs; TinyFish bundles the model, proxies and anti-bot into one price per unit of work.
On browser hours, every paid Solari rate sits below TinyBrowser's list price, so the saving grows with every hour your agents keep a browser open. On parallel work, every paid Solari plan runs more browsers at once than TinyBrowser's pay-as-you-go cap, so your agent covers a long list in one pass.
On extras, TinyFish folds proxies, anti-bot and the model into each run. Solari charges for proxies and CAPTCHA solves only on the sessions that use them and leaves the model bill with your provider.
What Role Does Solari Play?
Solari is the infrastructure your agent runs on: cloud browsers, sandboxes and desktops from one API. You bring the agent and the model; Solari gives it a place to work.
Pay only while a session runs. Solari bills a browser only while its session is open. A short task costs the minutes it used, not the idle hours around it.
Proxies and CAPTCHA only where you need them. Turn on stealth for sites that block automation, then add proxies at $6.00 per GB on Starter and $4.00 per GB on higher plans. CAPTCHA solves cost $0.01 each on Starter and half that on higher plans; public pages run with neither charge.
Logins that stay signed in. A Solari profile saves cookies and site data in the storage state format Playwright uses. Your agent signs in once, so it never spends paid time on a login page.
Your agent, your model. Solari works with Playwright and any client that speaks the Chrome DevTools Protocol. You pay your model provider directly and can run a cheaper model on simple pages.
Code and desktops on the same bill. Solari sandboxes run the code that cleans what the browser collects, at $0.0245 per vCPU-hour on Professional. Solari desktops operate apps with no API and add $0.02 per hour for the live screen.
TinyFish is the more established vendor for hosted web agents with the model built into the price; Solari is the younger company and moves faster on speed and price.
Where Is Agent Pricing Going Next?
Over the next year, agent pricing changes in four ways:
Prices per outcome. More vendors will charge for a finished task, not the steps behind it.
Bundles split at scale. Large fleets will ask for the model, proxies and compute on separate lines.
Spend limits by default. Prepaid balances with a hard stop will become the norm for agents that run all night.
Desktops priced like browsers. As computer use agents reach production, desktop hours will be compared the way browser hours are today.
What stays human is the budget: which jobs are worth running, how often, and what a result is worth.
Which Pricing Fits Your Agents?
Choose Solari when you run your own agent and model, need many browsers in parallel or spend most of your browser hours on public pages. The same balance then pays for the sandboxes and desktops your agent uses, so one account covers the whole job.
Stay with TinyFish when you want a hosted agent with the model included, your volume is low and you would rather not hold a plan. Its free search and fetch tiers suit research that never needs a full browser.
