What does DeltaGlider save you?

Type the numbers from your current AWS S3 bill and get an answer in 30 seconds, even when the answer is no. We don't ask for your email.

Your numbers

This is what aws s3 ls --summarize shows today across your bucket.

Enter how many regions DeltaGlider replicates this data to. Each region holds a full copy, so each one adds the full storage cost, and each one counts toward the 15 TB free grant.

This is the rate for the first 50 TB tier. Egress and API requests cost extra.

You'd save about $15k/year

Your license footprint is 6.0 TB, the compressed data times the regions. It stays under the 15 TB free grant, so DeltaGlider costs you nothing and the figure above is your net saving.

We normalise costs to USD per month for comparison and tag the providers priced in €. Minimum billing floors mean some bars can't shrink below about $6 to $8 a month, so DeltaGlider helps most where you store far above the floor. We leave egress and API fees out.

What you'd pay

Free & evaluation

Free

$0
You get the full product and host it yourself, with community support on GitHub. Production use is free up to 15 TB of compressed stored data per organization, counting every copy that DeltaGlider writes. Nothing is held back and there are no license keys. Every release becomes Apache-2.0 two years after it ships.

Commercial trial

Free, 30 days
For 30 days you get the full Commercial plan: direct engineering email, a 12h response SLA, and one architecture review call. See /trial.

Commercial

Commercial

$5k/year
The price is per organization, with unlimited instances, clusters and regions. It includes everything: use beyond the 15 TB grant up to 1 PB, direct engineering email with a 12h business-hours response SLA, signed builds with an SBOM, a CVE response commitment, and every new feature as it ships.

Enterprise & OEM

Enterprise

Talk to sales
This plan is for an organization whose stored footprint is above 1 PB, or that needs custom terms such as indemnity, a security review, or procurement paperwork. We agree the price and the terms with you.

OEM & embedding

Talk to sales
This plan is for two cases. The first is offering DeltaGlider, or a service whose primary value comes from it, to third parties as a hosted, managed or multi-tenant service. The second is shipping DeltaGlider inside or with a commercial product or appliance: the OEM license then covers your customers' use of the copy you ship them. The price depends on your use case.

What we mean by "stored footprint"

The stored footprint is the number of bytes that all of your organization's production deployments of DeltaGlider cause to be stored, measured after DeltaGlider's compression. It counts every copy that DeltaGlider writes: the primary data, the replicas and archives that DeltaGlider writes to other buckets or regions, and the reference and metadata objects that delta compression needs. Your source (logical) bytes, ingress, and egress don't count.

Bytes that your storage provider keeps for its own redundancy do not count, because DeltaGlider does not write them. For example, when you turn on S3 cross-region replication in your provider's console, the provider makes that copy, so it is not part of your footprint. When DeltaGlider's own replication writes the copy, it is.

The footprint is the average over a calendar month of one measurement a day, so a short spike does not push you over the line. Your organization is you together with every company that controls you, that you control, or that is under common control with you, where control means more than 50% of the voting shares.

We don't collect telemetry and the software never phones home. The admin dashboard and the /_/stats endpoint of each deployment show the compressed bytes that it stores, so you can add them up and see which side of the 15 TB line you are on. You self-report, and we cross-check against the /_/stats endpoint only if you give us read access during the conversation.

When do you need a paid license?

DeltaGlider is source-available under the Business Source License 1.1. The license grants free production use to most organizations, 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 organization's stored footprint exceeds 15 TB. Up to 1 PB, this is the Commercial plan, at the flat published price above. One plan covers the whole organization, with any number of instances, clusters and regions.
  • Your organization's stored footprint exceeds 1 PB, or you need custom terms such as indemnity, a security review, or procurement paperwork. That is the Enterprise plan.
  • You offer DeltaGlider, or a service whose primary value comes from it, to third parties as a hosted, managed or multi-tenant service. That needs an OEM license.
  • You ship DeltaGlider inside or with a commercial product or appliance. That needs an OEM license too, and it covers your customers' use of the copy you ship them. Without it, the free grant does not cover those customers.

Everything else is free: production use under the grant, and development, testing, and evaluation at any size. If your footprint is above 15 TB, the calculator above shows how the savings compare with the plan price.

Frequently asked

Is DeltaGlider still open source?

DeltaGlider is source-available. You can read and build every line of the public source, and there are no license keys. The license doesn't meet the OSI definition of open source. Every release automatically becomes Apache-2.0, an open source 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?

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 and up to 1 PB, every organization gets the same plan, with the license, support, and signed builds all included. The price is per organization, not per deployment, so a new cluster or region does not add to it. If your savings are $200k/yr, good: the price stays $5k.

Why is the plan $5k? That feels high for "support."

Support is only part of what you pay for. The $5k buys the license above the 15 TB grant, an SLA on critical infrastructure, and a direct email line to the engineers who wrote the proxy. The calculator above shows what DeltaGlider saves you at your size, compared with the plan price.

What happens if I cross the 15 TB line mid-year?

Nothing breaks and no feature switches off. The software keeps working, and the admin dashboard shows your footprint, so you can see when the monthly average crosses the line. At that point you buy the Commercial plan. The proxy doesn't phone home, and we send no surprise invoices.

Replication doubles my footprint. Do you count it twice?

Yes, when DeltaGlider writes the copy. The license counts every stored copy that DeltaGlider writes, so a bucket that DeltaGlider replicates to a second region counts twice. The redundancy that your storage provider runs by itself, such as S3 cross-region replication that you turn on at the provider, does not count, because DeltaGlider does not write those bytes.

What counts as my organization?

Your organization is your company together with every company that controls it, that it controls, or that is under common control with it. Control means more than 50% of the voting shares. So a parent company and its subsidiaries share one 15 TB grant and need one Commercial plan, not one for each subsidiary.

We run DeltaGlider for a client. Do we need OEM?

No, if you run it for one client inside infrastructure that the client controls. The license treats that as the client's own production use, so the client's footprint and the client's plan apply. You need OEM when you run DeltaGlider as a hosted, managed or multi-tenant service that you offer to third parties.

We ship a product that includes DeltaGlider

Then you need an OEM license. The free grant does not cover a copy of DeltaGlider that a customer received as part of a commercial product or appliance, unless the vendor holds an OEM license that covers that use. The OEM license covers your customers, so they do not each need their own plan.

What about a migration that briefly doubles a bucket?

The footprint is the average over a calendar month of one measurement a day. A migration that holds two copies of a bucket raises the average only for the days that both copies exist. For example, a second copy that exists for 3 days of a 30-day month adds a tenth of the bucket's size to that month's footprint.

I'm under the grant. Do I still get the trial?

Yes. The 30-day trial gives you the Commercial plan's support regardless of your size, so you can try it before you need it. See /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, where nobody waits on it. Reads pay about 30% on time to first byte when cold and nothing when warm. Encryption is effectively free. The measured numbers and the methodology are in the compute tax.

What stops me from just using the free grant forever?

Nothing, if you stay under it. The grant exists so that small teams, homelabs, and startups never pay. Above it, the license text itself requires a commercial license. The software doesn't enforce that, so whether you honor it is a question for your compliance process.
