Rebrand: LambdaTest → TestMu AI

On 12 January 2026 LambdaTest became TestMu AI. I owned the whole thing: website redesign, conversion work, the domain migration, and the brand's presence across hundreds of third-party platforms. Anyone can check the plumbing today.

Every legacy host (lambdatest.com, testmu.ai, the community subdomain) 301s to testmuai.com with self-canonicals on the new domain public (run curl -I https://www.lambdatest.com/).
The old name stays in page titles on purpose, as "TestMu AI (Formerly LambdaTest)", a brand-entity signal while search engines re-associate the two names; it is on virtually every page and anyone can crawl it public.

$ curl -I https://www.lambdatest.com/
HTTP/2 301
location: https://www.testmuai.com/

$ curl -I https://testmu.ai/
HTTP/2 301
location: https://www.testmuai.com/

$ curl -I https://community.lambdatest.com/
HTTP/2 301
location: https://community.testmuai.com/

$ curl -I https://www.lambdatest.com/selenium-automation
HTTP/2 301
location: https://www.testmuai.com/selenium-automation/

The legacy hosts today, headers trimmed to status and location. Public.

Five things that made it boring

One redirect map, tested raw with curl. Every pattern verified before launch and again after, without relying on a crawler.
Self-canonicals on the new domain from hour one. No canonical pointing back at the old brand, anywhere.
The old name kept in titles. We traded some click-through for entity continuity.
Organization schema with the old name as alternateName and every social and marketplace profile in sameAs, so the knowledge graph has one entity with two names.
Hundreds of third-party listings updated by hand: review sites, marketplaces, package registries and communities.

What I'd do differently

Start the off-domain work earlier. Search engines and AI assistants take their cue from the entity's footprint across other sites; the on-domain part is a week of engineering, the off-domain part is a quarter of persistence.

Proof

publictestmuai.com; the redirects from lambdatest.com; the title suffix on any product page.

Every figure carries how it is known: public links open for anyone; third-party corroborates direction from an independent source; stated is internal analytics, quoted with its date, with a walkthrough available in conversation.
