.dev vs .io
Both TLDs target the developer and tech community. The .io extension is more established with startups and has broader tech recognition, while .dev is newer, Google-backed, and requires HTTPS by default. The .io TLD faces some uncertainty due to geopolitical concerns.
Choose .io for established startup branding and SaaS products. Choose .dev for developer-focused projects, documentation, and tools where the HTTPS requirement aligns with your values.
