Selenium gave us browser automation. agent-qa adds intent, self-healing, and memory.
Selenium is the two-decade veteran of programmatic browser control. agent-qa is what the same job looks like now: plain-English tests, adaptive execution, and a harness built for coding agents.
Try agent-qa, the source-available AI QA agent that remembers what a decade of scripts never could.
agent-qa vs Selenium
| Capability | agent-qa | Selenium | Details |
|---|---|---|---|
| Plain-English authoring | Selenium tests are code plus locators plus explicit waits. agent-qa tests are natural-language YAML anyone can review. | ||
| Survives UI changes | XPath and CSS locators are Selenium's most famous failure mode. agent-qa re-plans from intent when the UI shifts and remembers the change. | ||
| Execution memory | agent-qa accumulates behavioral memory across runs; Selenium sessions know nothing about the last run. | ||
| Source access | Selenium is open source; agent-qa is source available under FSL-1.1-ALv2 and adds an AI harness on top of open foundations. | ||
| Local and CI execution | Both run anywhere. agent-qa needs no Grid topology to plan, execute, and report a flow. | ||
| Mobile app testing | Selenium's ecosystem reaches mobile through Appium as a separate stack. agent-qa covers web and native mobile in one contract. | ||
| Coding-agent native | agent-qa exposes MCP tools, Skills, artifacts, and failure classification designed for autonomous agents; Selenium predates the idea. | ||
| Wait/timing management | Explicit and implicit wait tuning is a Selenium discipline of its own. agent-qa's runtime observes actual app state while executing intent. |
Why teams retire Selenium suites for agent-qa
Decades of locator debt, gone
Legacy Selenium suites are archaeology: brittle XPath, page objects three refactors behind, waits tuned for servers that no longer exist. agent-qa lets you re-express what those tests were for, in English, and delete the debt instead of servicing it.
The team that can write tests gets bigger
Selenium coverage depends on engineers fluent in the framework. agent-qa tests are plain-English YAML, product engineers, QA specialists, and coding agents all author at the same speed, so coverage stops bottlenecking on framework expertise.
A harness from the agent era
Selenium was designed for humans writing scripts against browsers. agent-qa is designed for a world where coding agents change code continuously and need to verify it themselves, MCP tools, Skills, memory, and evidence built in from the start.
Selenium earned its place in history. agent-qa is what you'd build today: source available, but with intent instead of locators, memory instead of amnesia, and coding agents as first-class operators.
Frequently asked questions
Is agent-qa a good Selenium alternative?
Yes. It's the generational upgrade path. agent-qa replaces locator-based scripts with natural-language tests that self-adapt, remember prior runs, and produce reviewable evidence, while staying source available and repo-owned like the Selenium workflow you're leaving.
What does agent-qa cost compared to Selenium?
Selenium is free and open source. agent-qa is source available under FSL-1.1-ALv2 with no paid tier or license fee for FSL-permitted use. Selenium's hidden cost is the engineering time spent maintaining locators, waits, and Grid infrastructure; agent-qa trades that for LLM token spend under your control, with caching to keep repeat runs cheap.
How do I migrate a large Selenium suite to agent-qa?
Don't port code, harvest intent. Group your Selenium tests by user journey, write each journey as one agent-qa YAML test, and run both in parallel until trust is established. Teams typically find hundreds of scripts collapse into dozens of intent-level tests.
Does agent-qa need Selenium Grid or similar infrastructure?
No. agent-qa runs against local browsers, CI runners, and mobile emulators or devices you already have, there's no hub-and-node topology to operate, and no vendor cloud in the loop.
Can agent-qa test legacy web apps that Selenium currently covers?
Yes. agent-qa drives real browsers, so server-rendered and legacy UIs work the same as SPAs, often better than old Selenium scripts, because intent-based execution doesn't depend on the exact markup those scripts froze in time.

Each row names its own target, and a target is what decides where a test runs. This one names a web target, so it carries a URL.
Self-healing execution
When an action fails, agent-qa re-observes the screen and finds another route to the same outcome.
