TinyFish vs Browser Use: Features, Pricing and Scalability

Browser Use and TinyFish both help developers automate websites with AI, but they offer different approaches to building and running web agents. Browser Use provides an open-source framework for creating customizable browser agents, alongside Browser Use Cloud for managed execution. TinyFish provides managed web agent execution through an API, handling browser interactions and infrastructure as part of the service.

This comparison examines the differences in architecture, customization, pricing, scalability, and operational requirements to help developers evaluate which approach fits their workflow.

Browser Use vs TinyFish: Architecture and Deployment

Browser Use: Framework you build on

Browser Use gives you a Python framework for creating browser agents. You write the orchestration code, choose your LLM, and run the agent — either locally on your machine or on Browser Use Cloud.

The open-source version (MIT license) is fully self-hostable. You control the model, the browser, the proxy, and the retry logic. This is genuine developer freedom — and it's why 85K developers have starred the repo.

Browser Use 2.0, their custom-trained model, runs at ~$0.002/step when using your own infrastructure — roughly 7.5x cheaper per step than TinyFish's PAYG rate. For developers who already have browser infrastructure and want granular control, this is a significant cost advantage.

Browser Use Cloud adds managed infrastructure: hosted browsers, session management, and an API layer. Pricing starts at $0.03–0.06/hr for browser sessions, billed separately from AI agent tasks.

TinyFish: Platform you call

TinyFish abstracts the entire AI agent infrastructure stack into a single API call. You describe a task in natural language, and the platform handles browser execution, LLM reasoning, proxy rotation, infrastructure-level handling, and structured output — all server-side.

No framework to install. No browser to manage. No LLM to configure. The tradeoff: less customization, more abstraction.

Browser Use Cloud changes the operational requirements of the open-source approach by providing managed infrastructure for browser-agent execution. Developers evaluating Browser Use should therefore distinguish between running the framework themselves and using its hosted services. The open-source framework offers greater control over implementation choices, while the managed cloud offering reduces the infrastructure developers need to operate.

Benchmark Comparison

Both platforms have published Mind2Web results:

Both scores are self-reported and use different evaluation methods, which makes direct comparison imprecise. Browser Use uses a custom agentic judge and reports 97.7% when excluding 2 tasks classified as impossible. TinyFish uses standard evaluation and published all 300 execution traces for independent verification, but the 90% score was recorded in February 2026, and accuracy may have improved since then with model updates. Neither score has been independently replicated by a third party.

Benchmark scores are a useful signal, but production reliability depends on more than accuracy on a test set: infrastructure-level handling, session persistence, parallel execution, and failure recovery all factor in. The best benchmark is testing both against your actual target sites.

Note: Benchmark results should be interpreted in the context of their evaluation methods. Differences in task selection, success criteria, model versions, and judging approaches can affect reported scores. For production decisions, compare both platforms on the same target websites using identical task definitions and success criteria.

Scaling: The Core Divergence

This is where the architectural difference becomes a product difference.

Browser Use (open source): Runs on your machine. One browser, one session, one task at a time. If you need parallelism, you build it, spinning up multiple instances, managing resource allocation, handling failures across sessions. This is entirely doable for engineering teams with infrastructure experience, but it's infrastructure work.

Browser Use Cloud: Adds managed parallelism (up to 500 concurrent sessions), but browser sessions and AI tasks are billed separately. You're still managing the orchestration logic.

TinyFish:

TinyFish manages Agent execution and browser infrastructure through its API. Standard accounts support two concurrent Agent runs and five concurrent Browser sessions, with higher limits available through Enterprise. Teams running larger workloads can use asynchronous execution and workload-specific concurrency settings rather than managing their own browser fleet.

For production workloads, concurrency should be evaluated alongside task duration, queueing behavior, retry rates, and cost per successful workflow.

Pricing: Build vs Buy

The cost comparison depends on whether developers use the Browser Use open-source framework with their own infrastructure or pay for Browser Use Cloud. Self-managed deployments involve browser hosting, model usage, proxies where required, and engineering maintenance. Cloud offerings reduce some of that operational responsibility but introduce their own usage-based charges.

TinyFish uses a different billing model: Agent execution costs $0.016 per step, while Browser sessions cost $0.002 per minute. Search and Fetch are free within their published rate limits. A useful comparison should include both the direct execution cost and the engineering work required to maintain the workflow.

Site Compatibility and Infrastructure

Browser Use's open-source framework gives you full control over your stealth approach. The community commonly uses compatibility libraries and browser configuration patches for improved site access. You choose your proxy provider and configure rotation logic. This flexibility means you can fine-tune for specific target sites — but the maintenance is yours. Browser Use Cloud includes browser-level compatibility features and Cloudflare compatibility out of the box.

TinyFish's infrastructure-level handling works reliably on most sites with strict automation requirements automatically. Residential proxy rotation is included at no extra cost. The key difference is that TinyFish adapts automatically when access issues occur — without manual intervention. For a detailed breakdown, see our infrastructure handling guide.

Both platforms have limitations on the most aggressive enterprise-grade protection systems.

Browser Use vs TinyFish: Comparing a Real Workflow

Consider a workflow that needs to open a supplier portal, locate the latest product pricing, and return a structured list of products and prices. With Browser Use's open-source framework, developers can configure the agent, select the model, and control how the workflow is executed. With Browser Use Cloud, some of the execution infrastructure is managed. With TinyFish Agent, developers provide the starting URL and a task goal through the API.

The comparison should focus on how each approach handles setup, authentication, error recovery, structured results, and ongoing maintenance. The most relevant metric is not simply the number of API calls, but whether the workflow completes accurately and how much engineering effort is required to keep it reliable.

Decision Framework

Choose Browser Use (open source) if you:

• Want control over your agent framework, LLM selection, browser configuration, and orchestration logic.
• Prefer a self-hosted solution with access to the underlying source code.
• Have engineering resources to manage browser infrastructure, session handling, and ongoing maintenance.
• Need flexibility to customize agent behavior for specific workflows.

Choose Browser Use Cloud if you:

• Want managed browser infrastructure without operating your own browser fleet.
• Prefer working within the Browser Use ecosystem while reducing infrastructure management.
• Need cloud-based execution for browser agents, with usage-based pricing.

Choose TinyFish if you:

• Want to execute multi-step website tasks through a managed API using natural-language instructions.
• Need structured results without building and maintaining your own agent orchestration system.
• Want browser execution, model inference, and supporting infrastructure included in Agent's step-based pricing.
• Need managed concurrency, with two concurrent Agent runs available on standard accounts and higher limits through Enterprise.

The key difference: Browser Use's open-source framework prioritizes developer control, Browser Use Cloud provides managed execution, and TinyFish focuses on goal-directed web workflows through its managed API. The right choice depends on the level of customization, infrastructure management, and execution control your application requires.

Test Against Your Real Workflow

If you're already using Browser Use and it works for your scale — keep using it. The OSS community is strong and the per-step cost is hard to beat.

If you're hitting scaling limits, spending too much time on infrastructure, or need production-grade infrastructure-level handling without building it yourself — try the same workflow on TinyFish.

Upon sign-up, you'll have $8 available in Wallet credit (So you can run Agent and Browser before you add a card. Search and Fetch cost $0 credits).
