nostr.build is a media upload and hosting platform for the Nostr social ecosystem, operated by Big Nut Media LLC. It originally emerged as a free, community-oriented service for uploading images, GIFs, and videos. Rather than positioning itself as a traditional enterprise cloud drive or DAM, it provides ad-free, API-integrated, long-term media infrastructure for Nostr users, creators, and developers.
The platform supports uploads of images, audio, and video, while higher-tier paid plans also support files such as PDF, SVG, and ZIP. A key feature is that uploaded media has metadata removed, can be distributed via a global CDN, and can be posted directly to Nostr, with support for kind-1 notes and NIP-94 media events. For developers, it offers NIP96 and a Proprietary API, making it suitable for integration with Nostr clients or projects. Paid accounts include private folders, media deletion/moving, full backup downloads, media analytics, public Creator pages, and AI Studio text-to-image generation. The documentation also mentions ClamAV scanning for non-media files, multi-vendor/multi-region backups, and S3 backups.
nostr.build explicitly promises to maintain a free, ad-free service: the free plan supports files up to 7MB each and is hosted on Cloudflare. Paid plans accept only Bitcoin/Lightning and are billed annually: Purist offers 5GB for $18/year, Professional offers 25GB for $69/year, Creator offers 100GB for $120/year, and Advanced offers 500GB for $240/year. Discounts are available for 2-year and 3-year subscriptions. Compared with general-purpose media cloud services, the pricing is relatively low, but the payment method is highly niche.
Its strengths include being ad-free, having no third-party trackers, being Nostr-native, supporting open protocols and APIs, allowing downloadable backups, and helping avoid platform lock-in. CDN delivery, analytics, and AI generation also round out the creator workflow. The drawbacks are also clear: the terms state that the service is provided “as is,” with no guarantee of availability or file integrity; there is no evidence of team roles, enterprise SSO, audit logs, or compliance certifications; the free plan is quite limited, and Bitcoin-only payments are unsuitable for most enterprise procurement processes.
nostr.build is best suited to heavy Nostr users, decentralized social creators, Nostr app developers, and small community projects. It is not suitable as a formal digital asset management system, compliance archive, or large-scale object storage replacement for Chinese enterprises. The source text does not provide information on access status from mainland China. Since it involves Cloudflare/CDN and overseas services, real-world performance needs to be tested. On the payment side, Bitcoin/Lightning-only support creates a relatively high barrier for domestic users. Alternatives include Cloudinary, Imgur, Pinata, Filebase, as well as Qiniu Cloud, UPYUN, Alibaba Cloud OSS, and Tencent Cloud COS.
