Query your compressed archives in place.
Run SQL over compressed .at1 files in place, over HTTP, no decompress, no warehouse, no ingest. Your object storage (S3 / R2) holds the files; AT-1DB Cloud is the hosted query + verify layerover them. The engine runs server-side, so the browser never receives engine source, and every answer is checked against the file's SHA-256 manifest. Your storage, our hosted layer, nothing to run.
Your storage
The .at1 files live in your own S3, R2 or object store. AT-1DB Cloud queries them in place, the bytes never move into a warehouse, and there is nothing to ingest, copy or ETL.
SQL in place
Run predicates + projections straight against the compressed file over HTTP. Zone-maps and pushdown mean a selective query decodes only the blocks it touches, not the whole archive.
Verified every answer
The same query path re-checks the SHA-256 manifest, so every result is provably from the original, untampered file. Verification is free and account-less by design.
Nothing to run
The query + verify layer is hosted for you. No cluster, no engine to install, no server to keep patched, point it at a bucket and query. It all runs on our side, never in your browser.
The split is the point. Cold, compressed .at1 archives sit in your bucket, you own the bytes, the region and the access policy. Our managed query layer holds the engine and answers HTTP queries by fetching only the byte ranges a predicate needs. You get warehouse-style SQL over cold storage without paying to rehydrate it, and without standing up a cluster.
One API surface
A single POST /api/at1/query route, authenticated and metered per your plan. It decodes only the blocks your predicate touches and re-verifies integrity on the way out.
# run SQL over a compressed .at1 in your bucket, over HTTP, in place
curl -X POST https://tinyfiles.io/api/at1/query \
-H "authorization: Bearer $AT1_KEY" \
-d '{ "file": "s3://acme-cold/txns_2026.at1",
"sql": "select day, sum(amount) from t where region='EU' group by day" }'
# -> { ok: true, rows: [...], bytes_read: 1.2MB, scanned: "0.4% of file", verified: true }
# the browser console (query explorer) speaks the same route
# /dashboard/explorerWho this is for
- Cold-tier owners, years of compressed archives in S3/R2 that must stay queryable without a rehydrate bill.
- Data platform teams, a query + verify layer over object storage, with nothing to operate.
- Compliance & audit, every answer carries a re-checkable integrity guarantee against the original file.
- Regulated / sovereign data, the bytes never leave your bucket or region; only queries cross the wire.
AT-1DB Cloud is a hosted service, not a self-install. The query and verification layer runs on our side; your compressed files stay in your own object storage, we never take custody of your data. We provision your live endpoint when your account is set up. Before it's connected, the query explorerruns on sample data so you can try the workflow first, we won't show you a live endpoint we haven't stood up for you yet.
Your storage. Our hosted query + verify. Nothing to run.
