Best TLD for a Startup

The Decision Tree When com Is Taken

Pre-seed founders naming their API monitoring platform discover that every clean .com they want is either parked or priced in the five figures. This is the moment where TLD choice actually matters — and where bad advice can cost years of brand equity.

The forum consensus, distilled from hundreds of threads, follows a clear hierarchy. First, try modifying the name to fit a .com — adding 'hq,' 'get,' 'try,' or a relevant word often yields an available domain that users will remember more easily than any alternative TLD. As one IndieHackers commenter put it: 'prefix or suffix .com, because it is cheap and eliminates unknown issues.'

If name modification is not viable — perhaps the brand is already in use in conversations, pitch decks, or code repositories — then the alternative TLD decision hinges on three factors: who your audience is, whether you will send email from the domain, and your tolerance for renewal price uncertainty. Developer-facing products have more latitude with .io or .dev than consumer-facing ones.

Beyond com: What Each Alternative Signals

Each alternative TLD carries a distinct signal, and mismatching the signal to the audience creates friction that search rankings cannot overcome.

The .io extension has deep recognition in developer circles but carries geopolitical uncertainty around the Chagos Islands sovereignty transfer and a rising price trajectory. The .dev extension enforces HTTPS via HSTS preload — a technical plus — but costs several times more than .com annually. The .ai extension signals artificial-intelligence relevance, with a two-year minimum registration commitment and premium pricing. The .co extension is short and clean, but the typo-to-.com problem is real and persistent.

None of these are wrong choices in the right context. A developer tools startup can thrive on .dev. An AI research lab can justify .ai. The mistake is choosing an alternative TLD for aesthetic reasons without pricing the multi-year cost, checking email deliverability implications, and considering how non-technical stakeholders will perceive the extension.
