Datum Storage vs Lighthouse

Datum Storage is decentralized cloud storage running on the Datum Network, with access listed for Android, iOS, and API use. Datum Drive adds a virtual hard disk to a computer that behaves like a folder. The product says files are end-to-end encrypted and that users hold the key. Storage accounts attach to a Datum Identity, whose creation requires email and phone verification. For software connections, the service supports the Amazon S3 API format and custom S3 endpoints. After account creation, users receive a URL plus a key and secret corresponding to S3 access credentials; Datum recommends Signature Version 4 if a backup application offers a choice. Arq Backup for Mac and Windows is listed as tested. Duplicati, Duplicity, and Duplicacy are named as S3-compatible applications but have not been tested by Datum. The Datum ID app is listed in the App Store and Google Play for sign-up and credential and usage management, though the mobile workflow is described as coming soon. A free plan provides one terabyte for the first year. Additional storage is listed at US$3.99 per terabyte per month and is also described as coming soon.

Lighthouse combines decentralized file storage with a long-term memory service for AI agents. Lighthouse Memory saves project context, preferences, and decisions for retrieval in later sessions, with remember, recall, and forget operations. Its batched engine supports local hybrid retrieval using embeddings alongside keyword or tag matching. Memories are documented as verifiable, content-addressed blobs, and the hosted backend exposes tools through the Model Context Protocol for Claude Code, Claude Desktop, and other compatible agents. For files, Lighthouse uses IPFS and lists Filecoin and Walrus as storage networks; its web app supports storing, retrieving, and sharing files. Developers can use an SDK and CLI, while documented memory storage options include Lighthouse Walrus, Lighthouse IPFS/Filecoin, AWS S3, R2, MinIO, and a local folder. Plans include a free tier with 5 GB and 10,000 AI memories, Lite at $12 a month for 500 GB and 25,000 memories, and Premium at $49 a month for 2.5 TB and 100,000 memories. Encryption and other features are add-ons. Lighthouse cautions that forgetting a memory may not erase its stored blob, and content identifiers do not establish whether content is true.
