# agent-qa vs Browser Use

> Compare agent-qa vs Browser Use for recurring QA: repo-owned YAML expectations, application memory, MCP, failure evidence, and web and native mobile testing.

The Browser Use alternative built for recurring QA.

Turn a successful browser task into a regression test your team can review, rerun and diagnose, with application memory that stays beside the code.

Try agent-qa, a source-available QA runtime for maintained test coverage. It packages natural-language test definitions, application memory, web and native mobile execution, and step evidence into one repository-owned workflow that your coding agent and CI can run again.

## The choice for recurring QA

Choose agent-qa over Browser Use when you need recurring regression tests with explicit expectations, scoped application memory and diagnosable results across web and native mobile. Browser Use supplies flexible browser automation; agent-qa supplies the QA contract and lifecycle around the task.

## Capability comparison

- **Versioned regression expectations.** agent-qa: Yes; Browser Use: Partial. agent-qa provides YAML tests with stable IDs, named targets and verification steps. Browser Use’s Python library lets you keep task prompts and custom checks in your repo, but you build the regression-test contract around its general-purpose Agent API. Sources: [agent-qa test contract](https://vostride.com/docs/agent-qa/configuration/test), [Browser Use open-source library and Cloud distinction](https://github.com/browser-use/browser-use), [Browser Use agent configuration and custom tools](https://docs.browser-use.com/open-source/customize/agent/all-parameters).

- **Scoped behavioral memory.** agent-qa: Yes; Browser Use: Partial. agent-qa curates reviewable Markdown observations by product, suite and test. Browser Use has execution history, and its Cloud offering documents persistent memory and workspace files. agent-qa’s distinction is its built-in QA scopes, trust controls and observation lifecycle in your repository. Sources: [agent-qa behavioral memory](https://vostride.com/docs/agent-qa/memory), [Browser Use action history and structured output](https://docs.browser-use.com/open-source/customize/agent/output-format), [Browser Use open-source library and Cloud distinction](https://github.com/browser-use/browser-use), [Browser Use persistent Cloud workspaces](https://docs.browser-use.com/cloud/agent/workspaces).

- **Coding-agent access through MCP.** agent-qa: Yes; Browser Use: Yes. Both offer MCP integration. Browser Use documents local and Cloud servers for browser automation. agent-qa’s local MCP tools operate on tests, suites, execution jobs, artifacts and failure classification, giving a coding agent a QA workflow around the browser actions. Sources: [agent-qa MCP reference](https://vostride.com/docs/agent-qa/mcp), [Browser Use local MCP server](https://docs.browser-use.com/open-source/customize/integrations/mcp-server), [Browser Use Cloud MCP server](https://docs.browser-use.com/cloud/guides/mcp-server).

- **Web, Android and iOS QA.** agent-qa: Yes; Browser Use: Partial. agent-qa runs web tests and native Android and iOS targets through the same test format and CLI. Browser Use’s documented products automate web browsers. Testing a responsive website there is useful, but does not provide agent-qa’s native mobile target and device workflow. Sources: [agent-qa native mobile targets](https://vostride.com/docs/agent-qa/guides/mobile-testing), [agent-qa test contract](https://vostride.com/docs/agent-qa/configuration/test), [Browser Use hosted agent and browser products](https://docs.browser-use.com/cloud/quickstart), [Browser Use open-source library and Cloud distinction](https://github.com/browser-use/browser-use).

- **Test evidence and CI results.** agent-qa: Yes; Browser Use: Partial. Browser Use returns action history, screenshots, errors and structured output. agent-qa organizes evidence into test and step records, offers JUnit output for CI, and lets an agent inspect and classify a failed run without assembling that QA reporting layer itself. Sources: [agent-qa recorded evidence](https://vostride.com/docs/agent-qa/guides/recorded-evidence), [agent-qa coding-agent workflow and CI output](https://vostride.com/docs/agent-qa/guides/coding-agent-workflow), [Browser Use action history and structured output](https://docs.browser-use.com/open-source/customize/agent/output-format).

- **Reuse across repeated runs.** agent-qa: Yes; Browser Use: Yes. Browser Use Cloud can save scripts in persistent workspaces, reuse them against live sites and repair them when needed. agent-qa provides action-plan caching with contextual keys and invalidation, alongside separate behavioral memory. Both should be evaluated against unchanged regression expectations. Sources: [agent-qa action caching](https://vostride.com/docs/agent-qa/caching), [agent-qa behavioral memory](https://vostride.com/docs/agent-qa/memory), [Browser Use rerunnable scripts](https://docs.browser-use.com/cloud/agent/scripts).

- **Local execution and model choice.** agent-qa: Yes; Browser Use: Yes. Browser Use’s open-source library runs locally and supports multiple model providers; its hosted products are optional. agent-qa also runs locally or in CI with configured providers and endpoints. Its QA format lets the team review model selection together with test and run configuration. Sources: [agent-qa model and runtime configuration](https://vostride.com/docs/agent-qa/configuration/global-config), [agent-qa coding-agent workflow and CI output](https://vostride.com/docs/agent-qa/guides/coding-agent-workflow), [Browser Use open-source library and Cloud distinction](https://github.com/browser-use/browser-use), [Browser Use supported model providers](https://docs.browser-use.com/open-source/supported-models).

- **Test setup and side-effect verification.** agent-qa: Yes; Browser Use: Partial. Browser Use supports custom tools and deterministic initial actions. agent-qa packages setup, teardown and inline hooks as registered scripts in Docker sandboxes, with exported variables that YAML verification steps can check for API or backend outcomes. Sources: [agent-qa sandboxed hooks](https://vostride.com/docs/agent-qa/guides/hooks), [agent-qa test contract](https://vostride.com/docs/agent-qa/configuration/test), [Browser Use agent configuration and custom tools](https://docs.browser-use.com/open-source/customize/agent/all-parameters).

## Why choose agent-qa when the task becomes a test suite

### Make the expected result reviewable

A useful regression test specifies what must remain true. agent-qa keeps those expectations in YAML with the target, identity and run controls, so a reviewer can assess coverage in the same pull request as the implementation.

### Keep product knowledge with the tests

Let the memory curator preserve useful observations and deprecate contradicted ones. Product, suite and test scopes give future steps relevant application context without treating a past run as proof that today’s application still works.

### Complete the agent’s verification loop

Give your coding agent one workflow to validate a definition, run the web or native mobile journey, inspect failed-step evidence and rerun after a fix. Test artifacts and JUnit output make the same result useful to teammates and CI.

## Verdict

agent-qa is our choice for engineering teams that need maintained regression coverage across web and native mobile: the expected behavior, learned application context and failure evidence all have a defined place. Browser Use remains useful for general browser tasks and custom automation. Choose agent-qa when the result you need is a QA process the team can keep running and reviewing.

> Note: Browser Use’s open-source library, hosted agent and managed browsers are distinct offerings. This page identifies Cloud-specific persistence and reuse explicitly; the recommendation is for recurring QA and does not assert benchmark superiority over Browser Use.

## Evaluate agent-qa against Browser Use

1. Select a release-critical flow and write down the same expected visible state and backend side effects for both implementations before running either agent.
2. Use the same app revision and test data to run a passing build and an intentional regression. Verify the failed expectation from recorded evidence, not only the agent’s final text.
3. Repeat the flow using each tool’s available reuse mechanism. Record the model, elapsed time, token usage and retained files, and check that the regression still fails.
4. Ask your coding agent to inspect a failure and rerun the unchanged expectations after a fix. Include a native Android or iOS journey if mobile coverage is part of the release.

## Frequently asked questions

### Is agent-qa a Browser Use alternative for AI testing?

Yes. For recurring regression testing, agent-qa is our recommendation because YAML expectations, application memory, native mobile targets and QA evidence are part of its workflow. Browser Use is a flexible browser automation library and hosted service that you can use for QA; your application code supplies more of the testing structure around it.

### Is Browser Use only a paid cloud product?

No. Browser Use has an MIT-licensed open-source Python library that can run on your machine with your chosen model provider, as well as optional hosted products. agent-qa is source-available under FSL-1.1-ALv2 with no paid tier. Model usage and infrastructure can cost money in either local setup, so compare total operating costs for the configuration you intend to use.

### Does Browser Use already have memory and reusable workflows?

Yes. Its Cloud offering includes persistent memory and workspace files, and it documents rerunnable scripts that read live sites and can repair changed code. agent-qa’s reason to switch is its explicit QA memory lifecycle: reviewable product, suite and test observations, relevance-based retrieval and curation that can update or deprecate observations after runs.

### Can I keep Browser Use for scraping and use agent-qa for testing?

Yes. Keep Browser Use tasks that collect data or complete general web workflows. Put release-critical journeys into agent-qa tests with explicit outcomes, then run them from CI or your coding agent. These tools can serve different parts of the same repository without requiring an all-at-once migration.

### How do I turn a Browser Use task into an agent-qa regression test?

Start with the task’s intended outcome, identify the relevant named target and write its actions and verifications in an agent-qa YAML test. Move data preparation and API checks into registered hooks. Run both implementations against the same passing and intentionally broken builds, inspect the evidence, and retain the test only after it detects the expected regression. Python tasks do not import automatically.
