Filebase
Provides S3-compatible object storage with automatic IPFS pinning across Filecoin, Sia, and Storj backends, giving files a permanent content-addressed CID alongside a traditional object key.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
TLS enforced; S3 HMAC signing for request auth; no fine-grained IAM or per-bucket policies beyond account-level keys; data stored across third-party decentralized networks
⚡ Reliability
Best When
You want the ergonomics of S3-compatible storage while also needing permanent IPFS/Filecoin content addressing for web3-adjacent agent outputs.
Avoid When
Your use case is purely traditional cloud storage with no web3 requirements — dedicated providers like R2 or Backblaze B2 offer better performance and pricing.
Use Cases
- • Pin agent-generated content to IPFS for permanent, content-addressed retrieval without running your own IPFS node
- • Store NFT metadata and assets with both an S3 key and an IPFS CID from a single upload, enabling web3 and web2 access simultaneously
- • Archive agent outputs to decentralized storage (Filecoin) for provenance and immutability guarantees beyond what centralized storage provides
- • Use familiar AWS S3 SDK tooling in agent pipelines while gaining IPFS content addressing as a side effect of every upload
- • Distribute agent-generated datasets or models via IPFS gateways for censorship-resistant public access
Not For
- • Latency-sensitive read workloads — IPFS retrieval can be slow and unpredictable compared to centralized CDN-backed storage
- • Frequently mutated objects — IPFS CIDs are content-addressed and immutable; updates create new CIDs, making mutable-object patterns awkward
- • Enterprise workloads requiring strict SLAs, dedicated support, or compliance certifications beyond what a startup-scale provider offers
Interface
Authentication
Authentication uses S3-compatible Access Key ID and Secret Access Key generated in Filebase dashboard; endpoint is s3.filebase.com; no fine-grained scope support beyond bucket-level access
Pricing
Free tier is limited but suitable for prototyping web3 agent pipelines; bandwidth costs can add up if IPFS content is frequently retrieved via Filebase gateways
Agent Metadata
Known Gotchas
- ⚠ IPFS CID is generated asynchronously after upload — agents that immediately query the CID after PUT may receive a 404 from the IPFS gateway before pinning completes
- ⚠ S3 endpoint is s3.filebase.com (not a regional endpoint) — AWS SDK clients using auto-region-detect will fail unless endpoint override is configured
- ⚠ Bucket names on Filebase must be globally unique across all users (like S3), but error messages on collision are not always clear
- ⚠ Free tier bandwidth limit (1GB/month) is extremely easy to exhaust if agents serve content directly through Filebase's IPFS gateway
- ⚠ No lifecycle policies or automatic expiration — agents must implement their own cleanup logic to avoid unbounded storage growth
