agent-qa on GitHub,230stars

LambdaTest sells you a grid. agent-qa builds QA memory you keep.

LambdaTest supplies a large testing cloud priced around parallel sessions and platform tiers. agent-qa keeps the natural-language contract, LLM choice, and run evidence inside the repository workflow.

Try agent-qa, the source-available path where test intent and memory stay out of dashboards.

agent-qa vs LambdaTest

Capabilityagent-qaLambdaTestDetails
Source accessLambdaTest is not positioned as a repo-owned framework with published source, so behaviour you disagree with is a support ticket. With agent-qa it is a pull request.
Repo-owned YAMLLambdaTest keeps the test intent inside its own product. agent-qa keeps intent, config, hooks, memory and suites beside the code they cover, where your engineering process already works.
Coding-agent nativeA coding agent cannot click through a hosted editor. agent-qa ships MCP tools, packaged Skills and a CLI, so the agent that changed the code writes the test, runs it and reads the failure without leaving the loop.
Bring your own LLMWhoever picks the model sets your quality ceiling and your bill. agent-qa lets you point at any provider, any compatible endpoint, or a model on your own hardware, and change it in one line.
Local and CI executionOne command on a laptop, in CI, and from an agent. No run depends on somebody else's control plane being up, and nothing queues behind another tenant.
Web and mobile QAWeb, Android and iOS from the same natural-language flow and the same evidence model. The surface is a target named in a file, not a different product tier.
Memory, cache, hooksExecution memory, a validated action cache and sandboxed hooks compound. A suite that has been running a month is faster, cheaper and better informed about your app than the day it was written.
No platform lock-inEvery durable asset stays in your repository. Cancel agent-qa tomorrow and the tests, the memory and the evidence are still there and still readable.

Why teams switch from LambdaTest

Your tests stop being hostages

Every test you write in LambdaTest makes leaving LambdaTest more expensive. That is not an accident, it is the business model. Every test you write with agent-qa is a YAML file in your repository: reviewed in a pull request, portable to any runner, and still yours the day you cancel.

Runs compound instead of resetting

LambdaTest runs a test and forgets. Every run starts from nothing, which is why the hundredth run costs exactly what the first one did. agent-qa writes what it learned into memory committed beside your tests, so the next run starts where the last one finished and the suite gets better at your app on its own.

Grid minutes meet agent economics

Cloud-grid pricing made sense when humans wrote every script and ran suites nightly. Coding agents verify continuously, and per-session platform pricing punishes exactly that. agent-qa runs where your compute already is, gated only by the LLM budget you set.

LambdaTest wants to be where your testing happens. agent-qa makes your repo that place, and lets you rent, own, or skip infrastructure as you see fit.

Frequently asked questions

Is agent-qa a good LambdaTest alternative?

Yes, and the reason is structural rather than a feature count. LambdaTest is a cloud testing platform selling browser/device infrastructure and an AI test control plane, which means the asset you are building lives on their side of the line. agent-qa is a source-available QA agent with no paid tier, governed by FSL-1.1-ALv2: tests are plain-English YAML in your repository, runs execute on your laptop, in your CI, or from your coding agent, and every run writes back into memory committed beside the tests. The suite gets better at your app whether or not you renew anything.

How much does agent-qa cost compared to LambdaTest?

LambdaTest is priced on per-parallel-session and platform-tier subscriptions, so the bill tracks how much you test. agent-qa has no paid tier, no seats and no platform fee; FSL-1.1-ALv2 governs permitted use. You pay for the model tokens and infrastructure you already control, on the provider you choose, and the validated action cache takes roughly 60% of the tokens off a matched rerun. Adding coverage does not add a line item.

How do I migrate from LambdaTest to agent-qa?

You are re-describing intent, not porting code, which is why this is far smaller than a normal test migration. Keep any infrastructure you like. The migration is moving the test contract out of the platform: re-express your covered flows as agent-qa YAML and run them wherever suits you. Run npx agent-qa init, write each critical flow as a plain-English YAML test, and let the runtime work out the selectors and the recovery. Most teams move a smoke suite in an afternoon, and there is nothing to un-pick later because the output is files in your own repository.

Does agent-qa cover web and mobile like LambdaTest?

Yes, and from the same file. agent-qa runs end-to-end tests on web, Android and iOS with one natural-language format, one memory store and one evidence model, so a flow written once survives being pointed at another surface. LambdaTest offers device clouds; agent-qa executes mobile E2E through your own local or CI device setup, keeping evidence in the repo.

Does agent-qa provide testing infrastructure like LambdaTest?

No, deliberately. agent-qa is the harness, not the hardware: it runs against local browsers, CI runners, emulators, or devices you already have. That separation is why there's no per-session meter and why your tests aren't coupled to anyone's cloud.

Where agent-qa pulls ahead of LambdaTest

The parts of agent-qa that answer what LambdaTest leaves you carrying.

Web, Android, and iOS

Point the same natural-language flow at a web target, an Android build, or an iOS build. Playwright and Appium are execution kernels here, not code generators: no test script is ever produced. The agent decides on each action from what it can currently see, and the kernel performs it, whether that is a click in Chromium, a tap on a local emulator, or a gesture on a remote device.

Learn about mobile testing

Execution kernels

Playwright and Appium only perform the actions the agent decides on. No test script is generated, and nothing is replayed from a recording.

Three web engines

Run the same flow on Chromium, Firefox, or WebKit, and override the engine, viewport, or headless mode per test.

Native and remote devices

Drive real Android and iOS builds by app package or bundle ID, on a local emulator, a simulator, or a remote device.

Caching and token optimization

agent-qa never generates a test script. Every run works out how to satisfy each step from what is on the screen at that moment, which is why a test survives a redesign that would have broken a recorded one. Working an action out costs tokens and wall clock, so a validated one is kept and reused the next time the screen still matches, and thinking is spent only on what actually changed. The suite gets faster and cheaper the longer it lives, and none of that speed comes from freezing it into a script.

Learn about caching

No script to generate

Nothing is recorded or compiled. Each run decides its own actions, so there is no generated file sitting between your app and the test.

Reused while it holds

A validated action is reused only while its target and the surrounding screen still match. Anything else goes back to the model.

Cheaper the longer it lives

Every proved run leaves less for the next one to work out, so a suite gets quicker and costs less without being frozen in place.

Execution speed

5x

42s to 8s

A run that meets screens it has already proved spends its time acting rather than deciding.

Token saving

60%

less token usage

A reused action never reaches the model, so the only thinking billed is the thinking your app made necessary.

Version controlled, built for teams

Tests, suites, hooks, and the workspace config are files you write. What it learns about your app, the bugs it files, the rules you assert, and the skills an authoring agent uses are files agent-qa writes, in a visible directory beside your tests rather than in a database you cannot read. All of it is committed, so a new memory bundle arrives as a diff in a pull request with the evidence that justified it. Only derived indexes and binary run artifacts are gitignored, because they rebuild from what is committed. A teammate, a coding agent, and CI check out one commit and get the same brief.

Learn about configuration

Files, not a database

What you author and what the agent learns sit next to each other as committed files. Nothing it knows is locked in a store you cannot open.

Learning arrives as a diff

A new memory bundle or a filed issue shows up in a pull request, with the evidence behind it, and is approved the way any other change is.

Everyone reads the same commit

A teammate, a coding agent, and CI work from one checkout, so no run is quietly using state that nobody else has.

Bring your own model

The model is a setting, not a rewrite. Point a workspace at an OpenAI or Anthropic compatible endpoint, at Gemini, at an open-weight model running on your own hardware, or at a subscription your team already pays for like Codex or Claude Code, and override it on the one test that needs something stronger than the rest. Nothing about how a test is written changes when the model does, because the test says what should happen and the model is only what works out how to get there. There is no vendor to be locked to and no key of ours to buy.

Learn about LLM providers

Swap it in one line

The provider, the endpoint, and the model are config. Change them and every test you have already written runs against the new one, unedited.

The seat you already pay for

Account-backed authentication works where the provider allows it, so a Codex or Claude Code subscription can drive runs without a second bill.

Or nothing leaves the building

Point it at an open-weight model on your own hardware when the code under test is the kind that cannot go to somebody else's API.
