Your numbers
What aws s3 ls --summarize shows today across your bucket.
How many regions you replicate this data to. Each adds full storage cost.
First 50 TB tier · egress + API extra
You'd save approximately $15k/year
Your compressed footprint stays under the 15 TB free grant, so DeltaGlider costs you nothing — the savings above are the whole story.
| Today | With DeltaGlider | |
|---|---|---|
| Storage footprint | 30 TB | 3.0 TB |
| Storage cost (per region) | $8,479 | $848 |
| Replicated across 2 regions | $16,957 | $1,696 |
| Replication egress (new artifacts) | $184 | $18 |
| Subtotal — storage + transfer | $17,142 | $1,714 |
Costs normalised to USD/month for comparison (€-priced providers tagged). Min-billing floors mean some bars can't shrink below ~$6–8/mo — DeltaGlider helps most where you store far above the floor. Egress & API fees excluded.

What we mean by "compressed stored footprint"
Compressed stored footprint = the bytes physically stored on your
backend across all DeltaGlider-managed buckets, after
DeltaGlider's compression. This is the number the license grant
is measured on, and it is the number DeltaGlider already shows
you — in the admin dashboard and at /_/stats. It is
not your source (logical) bytes, and it is not ingress or egress.
Storage-layer replicas (whatever your backend does under the
hood) don't count.
We don't collect telemetry and the software never phones home.
Your own dashboard tells you which side of the 15 TB
line you are on; you self-report, and we cross-check via the
/_/stats endpoint only if you give us read access
during the conversation.
When do you need the Commercial plan?
DeltaGlider is source-available under the Business Source License 1.1. The license itself grants free production use to most deployments, and every release becomes Apache-2.0 open source two years after it ships. You need a paid license only if one of these applies:
- Your total compressed stored footprint exceeds 15 TB per organization — that's the Commercial plan, at the flat published price above
- You offer DeltaGlider itself to your customers as a hosted or managed service — that's an OEM conversation
- You embed DeltaGlider in a proprietary product you distribute — also an OEM conversation
Everything else is free: internal infrastructure under the grant, development, testing, evaluation at any size. If your compressed footprint is above 15 TB, DeltaGlider is saving you far more than the plan costs — that is exactly what the calculator above shows.
Frequently asked
Is DeltaGlider still open source?
It is source-available: the full source is public, you can read and build every line, and nothing is gated behind a license key. It is not open source by the OSI definition — but every release automatically becomes Apache-2.0, a fully open license, two years after it ships. Releases up to v1.17.0 were GPL-3.0 and stay GPL-3.0 forever.
Why one flat price instead of brackets?
Because support effort doesn't scale with your bytes, and charging more the better the compression works taxed the product for doing its job. Above the free grant, every deployment gets the same plan: license, support, signed builds, everything. If your savings are $200k/yr, good — the price stays $5k.
Why is the plan $5k? That feels high for "support."
It isn't support alone — it's the license above the 15 TB grant, an SLA on critical infrastructure, and a direct email line to the engineers who wrote the proxy. Above the grant your compressed footprint implies hundreds of terabytes of source data, and the calculator above typically shows savings 10 to 40 times the plan price.
What happens if I cross the 15 TB line mid-year?
Nothing breaks and nothing gets gated. The software keeps working; the admin dashboard shows your footprint. You buy the Commercial plan when you cross the line — measured honestly, no surprise invoices, no phone-home.
Replication doubles my footprint — am I being double-counted?
No. We count logical compressed bytes managed by DeltaGlider. Storage-layer replicas don't count.
I'm under the grant — do I still get the trial?
Yes. The 30-day trial gives you the Commercial plan's support relationship regardless of your size, so you can try it before you need it. /trial
How do I get a real compression number on my own data?
Run
docker run --rm -it -p 9000:9000 -v dgp-data:/data -e DGP_AUTHENTICATION=none beshultd/deltaglider_proxy,
copy a sample of your data in, and read the Delta Efficiency
Panel at /_/admin/diagnostics/delta-efficiency.
No data leaves your network. Or talk to us and we'll help you
set it up.
What does it cost in speed?
The compute tax lands on writes, once: delta-encoding makes a single-stream upload roughly twelve times slower, on the CI path nobody waits on. Reads pay about 30% on time to first byte when cold and nothing when warm; encryption is effectively free. Measured numbers and methodology: the compute tax.
What stops me from just using the free grant forever?
Nothing, if you stay under it — that's the point. The grant exists so that small teams, homelabs, and startups never pay. Above it, the license text itself requires a commercial license; whether you honor that is a question for your compliance process, not for our software.
