Pixieset is the name most photographers know for client galleries. They started there and built everything else around it. Pixieset is a strong choice. Their website builder is designed to complement the galleries.
BluDomain is the opposite. The website is the foundation. Your galleries, your proofing, your portfolio, your blog, your contact page, all designed together as one experience from day one. Client proofing is built into the platform, not added on after the fact.
If your only need is delivering galleries to clients, Pixieset is a great choice. If you want a complete photography website with proofing included, that’s what BluDomain was built for.
