Lighthouse
Lighthouse combines decentralized file storage with a long-term memory product for AI agents.
What Lighthouse is
Lighthouse combines decentralized file storage with a long-term memory product for AI agents. Memory can retain project context, preferences, and decisions for retrieval in later sessions, with remember, recall, and forget operations. Its batched engine supports local hybrid recall using embeddings alongside keyword or tag matching. A hosted backend exposes tools through the Model Context Protocol for Claude Code, Claude Desktop, and other compatible agents. For files, Lighthouse provides storage powered by 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 choices include Lighthouse Walrus, Lighthouse IPFS/Filecoin, AWS S3, R2, MinIO, and a local folder. The Free plan includes 5 GB and 10,000 AI memories. Lite costs $12 a month, and Premium costs $49 a month. Lighthouse notes that forgetting a memory may not erase its stored blob, and content identifiers verify matching content, not its truth.
Good
- Free plan includes 5 GB and 10,000 AI memories.
- Supports IPFS, Filecoin, and Walrus storage networks.
- SDK and CLI support application pipeline integration.
- Recall can combine embeddings with keywords or tags.
Watch out
- Forgetting a memory may not erase its stored blob.
- Content identifiers do not establish whether memory content is true.
- Encryption is an add-on on the listed plans.
Who it suits
Lighthouse may suit developers building agent workflows who want persistent memory and distributed file storage, as well as users who need a web app to share files. Its MCP backend is relevant to users of Claude Code, Claude Desktop, and other MCP-capable agents.
Verdict
Lighthouse brings agent memory and decentralized file storage into one service, with both API and web access. Review the memory deletion and encryption limitations alongside the plan limits before choosing it.

What it does
- Agent connection
- The hosted memory backend exposes tools through the Model Context Protocol for Claude Code, Claude Desktop, and other MCP-capable agents.checked 7 Oct 2026
- Deletion limits
- Lighthouse says forgetting a memory may not erase its stored data, because removing a record from an index does not erase an existing stored blob.checked 7 Oct 2026
- Developer tools
- The storage product offers an SDK and CLI for integration into application pipelines.checked 7 Oct 2026
- Encryption
- The storage page describes an encryption SDK with threshold encryption and token gating, while the memory documentation says batched blobs and index snapshots are unencrypted and Memwal uses SEAL-encrypted blobs.checked 7 Oct 2026
- Integrity limits
- Content identifiers can verify that retrieved memory matches saved content, but Lighthouse says they do not establish whether the content is true.checked 7 Oct 2026
