Reflag (Bucket): sovereignty score and 8 European alternatives

Bucket now operates as Reflag and is a feature management platform for SaaS products built in TypeScript. It offers self-cleaning feature flags, where stale flags are archived and obsolete code is removed, a CLI for type safety, SDKs for React, Vue, Next.js and Node.js among others, a browser toolbar for toggling features, local evaluation, early-access grants for beta users, monitoring of feature adoption, and in-app feedback capture. It integrates with Linear and Slack. The service is delivered as SaaS and is aimed at product and engineering teams.

On data residency, Reflag states that requests are served through globally distributed edge servers by default. EU-only residency is available on request: you then point the SDK at Reflag's EU endpoint. The documentation describes only a vendor-hosted service.

Why digital sovereignty matters with Reflag (Bucket)

Reflag (Bucket) is headquartered in DK and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Reflag (Bucket) hosts data in EU, US, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Reflag (Bucket) 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 Reflag (Bucket) together with your other vendors and gives a total score, a heatmap and the main risk drivers.
