Should you pick .io?
The TLD you pick says something to your audience before they ever read your content. .io signals developer tools, dev-focused saas, technical products. If your product fits that audience, the right TLD shortens your pitch.
The other consideration is cost. .io runs at $25–$40 / yr, which adds up over years. If you're bootstrapping, weigh whether the category signal is worth the recurring spend versus a cheaper .com or .co.
