LambdaTest vs self-hosted Playwright
Before comparing grids, it's worth asking whether you need one. A lot of suites that pay per parallel session only ever touch current Chromium, Firefox and WebKit — and Playwright ships all three, free, on any CI runner. This page is the honest version of that argument, including the three ways to own or rent capacity without a per-session subscription: Playwright in your CI, Playwright Workspaces per minute, and Moon or Selenium Grid 4 on Kubernetes.
Drop the grid if your matrix is modern-browser-only: Playwright's bundled engines plus sharding across CI runners cover it for $0 in licences. Keep a cloud if you need real iOS and Android hardware, desktop Safari without owning Macs, old browser versions, or interactive manual sessions — that's hardware, and hardware is what you're renting. In between, per-minute Playwright Workspaces at $0.01/Linux minute or Moon's $5 per parallel session are cheaper shapes than a fixed per-parallel subscription.
Side by side
Four ways to get browsers
| LambdaTest (TestMu AI) | Playwright, self-hosted | Playwright Workspaces | Moon / Selenium Grid 4 | |
|---|---|---|---|---|
| Who runs it | Vendor | You, on existing CI runners | Microsoft (Azure) | You, on Kubernetes |
| Cost | $79–$199 per parallel session/mo | $0 licence + runner time | $0.01/min Linux · $0.02/min Windows | Moon: 4 free, then $5/session/mo · Grid: $0 |
| Browsers | 3,000+ combos incl. legacy versions | Bundled Chromium, Firefox, WebKit | Chromium, Firefox, WebKit (hosted) | Whatever you put in the images |
| Real devices | ✓ 10,000+ (top tier) | ✗ emulation only | ✗ | ✗ |
| Frameworks | Selenium, Playwright, Cypress, Puppeteer, Appium | Playwright | Playwright only | Moon: Selenium, Playwright, Cypress, Puppeteer · Grid: WebDriver |
| Parallelism limit | What you pay for | Your runner capacity | Effectively elastic, billed per minute | Your cluster capacity |
| Dashboards & video | Built in | Playwright HTML report, traces, video artifacts | Azure integration | Moon has a UI; Grid needs add-ons |
| Ops burden | None | Low — a container image and CI config | None | Real: cluster, images, upgrades |
| Free tier | 100 lifetime automation minutes | Unlimited, it's Apache-2.0 | 100 test minutes in a 30-day trial | Moon 4 sessions · Grid unlimited |
Selenium Grid 4.41.0 (February 22, 2026) runs Dynamic Grid natively inside Kubernetes, creating an ephemeral browser Pod per session and treating scaling as intrinsic to the Grid rather than a KEDA add-on — the main reason self-hosting is less painful than its reputation. Aerokube's older Selenoid stopped being maintained on December 17, 2024; Moon is its successor.

A fair call
Which one fits you
Self-host if…
- Your matrix is current Chromium, Firefox and WebKit — Playwright covers it out of the box.
- You already have CI runners with spare capacity, or a Kubernetes cluster with autoscaling.
- The grid bill is a visible line in your budget and the suite isn't growing in browser breadth.
- Data residency or network isolation makes shipping traffic to a vendor awkward.
Keep a cloud if…
- You test on real iOS and Android hardware — no self-hosted grid gives you that.
- You need desktop Safari and don't want to run and maintain macOS runners.
- Your matrix includes old browser and OS versions you can't build images for.
- Manual, interactive sessions on devices you don't own are part of QA's day.
- Nobody on the team wants to own a grid — that's a legitimate answer, and the subscription is what it costs.
Common questions
Self-hosting vs a rented grid — common questions
Can Playwright replace a cloud browser grid?
For a web-only suite on current browsers, usually yes. Playwright ships its own builds of Chromium, Firefox and WebKit, so one npx playwright install gives you three engines on a Linux CI runner, with parallel workers, sharding across machines, retries, traces and video built in. What it can't give you is real iOS and Android hardware, real desktop Safari unless you run macOS runners, or the long tail of older browser versions. Those are the things a grid actually rents you.
Is self-hosting really cheaper than LambdaTest?
In licence terms yes — Playwright and Selenium Grid are free and open source, and Moon is free for 4 parallel sessions then $5 per session per month. You trade the subscription for compute and operations: runner minutes or Kubernetes nodes, container images to keep current, and someone who owns the grid when it breaks on a Friday. The honest comparison is your per-parallel bill against runner cost plus a share of an engineer's time — not against zero.
What is Playwright Workspaces and how is it priced?
It's Microsoft's hosted Playwright browser service, now part of Azure App Testing, billed purely by usage: $0.01 per Linux test minute and $0.02 per Windows test minute, metered by the second, with a 30-day trial covering the first 100 test minutes and no per-parallel subscription. It runs Playwright only and offers no real devices. Note the older standalone "Microsoft Playwright Testing" product was retired in 2026, so the $0.0002/minute figure in older blog posts no longer applies.
