Free tier	No account, no key, no quota. Docs quote only a per-request limit: 'Most aggregators and publishers limit requests to 10 MiB by default'. In practice the reference publisher accepted 300 MiB and 1 GiB. Max storage duration is 53 epochs; on Testnet 1 epoch = 1 day. unit mixed; metered on stored-bytes
Price	none stated
Per-object cap	per-object-cap: 1 GiB (1073741824 bytes)
Retention	retention: 53 epochs max, 1 day per epoch on Testnet = 53 days, and 'Walrus wipes the data periodically without warning' (1 days)
Egress	unmetered. Reads are served by ~55 independent community aggregators plus the Mysten reference aggregator; all returned CORS-open bytes with no metering observed and no auth header.

Limits	retention-clamped retention: 53 epochs max, 1 day source per-object-cap per-object-cap: 1 GiB source per-object-cap: 1 GiB verified write; read path has a per-object-cap of 500 MiB on the Mysten reference aggregator (403 SIZE_EXCEEDED, 'the blob size exceeds the maximum allowed size: 524288000') while community aggregators served the same 1 GiB blob fine. retention: 53 epochs max, 1 day per epoch on Testnet = 53 days, and 'Walrus wipes the data periodically without warning'. request-rate: 10 x 1 MiB PUTs back-to-back all returned 200, no shaping seen; no rate limit documented on Testnet.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest, cli rest
Tooling	Plain HTTP: PUT $PUBLISHER/v1/blobs?epochs=N --upload-file; GET $AGGREGATOR/v1/blobs/<blobId>. OpenAPI at /v1/api. Machine-readable operator list at https://docs.wal.app/operators.json (updated weekly). Walrus CLI + TypeScript SDK also exist (github.com/MystenLabs/walrus).
Composes with	16 public Testnet publishers in operators.json (3 live-tested: walrus.space, tududes, banansen) x unlimited keyless PUTs x unlimited blobs. Any number of blobs per publisher; distinct content hashes so no account dimension is needed at all. Store 10 TiB as 20,000 x 500 MiB blobs, or 10,000 x 1 GiB against community aggregators. Also: 53-epoch max means re-upload on a rolling schedule, so 'capacity' = (publishers x disk) not a per-identity tier.
Reliability	Testnet is periodically wiped without warning and publishers are volunteer-run (2 of 5 tested endpoints were down: h2o-nodes 502, atalma connection refused); treat as ephemeral, not archive.
Notes	No account, no key, no quota. Docs quote only a per-request limit: 'Most aggregators and publishers limit requests to 10 MiB by default'. In practice the reference publisher accepted 300 MiB and 1 GiB. Max storage duration is 53 epochs; on Testnet 1 epoch = 1 day.
