Bolt.new: sovereignty score and 6 European alternatives

Bolt.new is an AI builder with which users create websites, apps and prototypes in the browser by chatting with an agent. The Bolt Agent routes each task to a model. Bolt Cloud gives projects databases, user management and authentication, among other things; Bolt also offers hosting with analytics and custom domains, and lets you build on your own design system. The service is entirely web-based and delivered as SaaS.

Bolt.new is run by StackBlitz, Inc., a US company in San Francisco. Its privacy policy says the company is headquartered in the United States and that personal information may be transferred to, processed and stored in countries outside your jurisdiction, including the United States, with standard contractual clauses as a safeguard where required. The sources consulted name no European data region. The list of sub-processors is on the trust centre, which lists SOC 2 Type 2, GDPR and CCPA. Bolt.new itself is not open source; the separate, MIT-licensed fork bolt.diy can be self-hosted.

Why digital sovereignty matters with Bolt.new

Bolt.new is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Bolt.new hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Bolt.new is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Bolt.new together with your other vendors and gives a total score, a heatmap and the main risk drivers.
