0G Storage vs Lighthouse

0G Storage is a distributed storage layer for onchain applications, including AI agents, DePIN, and gaming. It provides an append-only Log Layer for unstructured data and a mutable Key-Value Layer for structured data. The product page describes 50 Gbps throughput for the Log Layer, millisecond-level access to structured and unstructured data, and sub-second access for the KV Layer. Cryptographic proofs, erasure coding, sharding, and Proof of Random Access challenges support integrity and availability. Uploads are committed on-chain as Merkle roots, while mutable states preserve immutable history. Listed workloads include datasets, media, AI model weights, sensor logs, vector embeddings, user state, and metadata. Developers can use TypeScript or Go SDKs, a CLI, or a web upload tool. It integrates with blockchains, rollups, VMs, hybrid stacks, and Web2 applications. Pricing starts at $11/mo, with API, Linux, macOS, self-hosted, and web access.

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.
