The platform is open source and complete; you don’t need a plan to run it. A plan is insurance for the layer everything else runs on: when something breaks, the people who built the product work it with you, at a flat yearly rate you can read off this page. You’re not paying an expert to spend hours figuring it out — you’re paying the one who already knows.
Your price has two inputs: how big your deployment is, and how fast you want us on the hook. Size is the band — deliberately structural, it moves when your network changes shape, not when a meter ticks. Find the card that looks like your estate; the three plan prices are on it.
One location, one network, a single control plane: everything lives on one site, and one team can hold the whole estate in its head. Clustering and HA aren’t covered on Small.
Typical: Small or mid-size business, non-profit, municipal office
Support plans · CAD per year
A main site plus satellites: several connected locations whose records must stay consistent as changes propagate between them.
Typical: Mid-size university, hospital network, city government
Support plans · CAD per year
A distributed estate: many sites or regions, and enough surface that DDI has its own on-call.
Typical: Large research university, health system, multi-region enterprise
Support plans · CAD per year
Add-on
24×7 severity-1 path+$15,000+$12,750a year, added to any Standard plan, in every bandWaitlist — est. Q3 2027
An add-on to Standard, not a fourth plan: a 24×7 path that pages our on-call, for severity 1 only — DNS or DHCP down for a site or a campus. Everything else stays Standard: same-business-day response, named contact, quarterly reviews. It isn’t Premium: no HA architecture review, no roadmap input.
Education & public sector prices: 15% off list on support plans and training, for publicly funded institutions — universities, colleges, school boards, hospitals, municipalities and government bodies. Confirmed at onboarding.
The software is $0 forever — every feature, no paywall. Plans price the response.
Response: Business hours, next-business-day response
Production support for teams that mostly run it themselves.
Response: Same-business-day response
For estates where DDI has an on-call rotation.
Response: 24×7 critical-response path
For fleets where DDI is a 24×7 concern.
Count two things: physical locations, and DNS/DHCP server nodes. Your band is the higher one that either count reaches:
* Counted as physical locations, as drawn on each card; servers are counted separately, as nodes. No per-IP metering — your band moves when you open a campus, not when you add a device. A location (“site”) is one physical place with its own network: a campus, a plant, an office, a data centre. A dedicated DR facility counts as one. A domain isn’t a location, and a second DNS server isn’t a second location.
The same grid with the fine print — renewal escalation, discount rules, currency policy, and exactly what each plan covers.

Anything the fixed-price catalogue does not cover.
If a managed service provider runs your network, support can reach you through them: they stay your help desk, and we back their certified operators. Partner pricing has its own page.
No. The whole platform is Apache 2.0 — every feature, every driver, every API. Plans buy response: someone on the hook when you need them, not access to functionality you already run.
Your band is the higher of two counts — locations and server nodes — assigned at onboarding and revisited at renewal. Bands move when your estate changes shape (a new campus, a new region), never because a device count ticked up.
You keep a fully working system and all the source code, forever. Apache 2.0 means continuity does not depend on us — no proprietary vendor can offer that.
Essential, yes — today, on early-adopter terms while the product is in beta; there’s no general release yet, and we say so. Standard opens when the staffing behind its same-day promise exists; Q3 2027 is our honest estimate, and the waitlist hears first. Premium commits us to 24×7, so it starts with a conversation and gets staffed per contract. We’d rather sell you the SLA we can honour than the one that demos well.
Yes, for the case that matters at 3 a.m. The 24×7 severity-1 path is a flat yearly add-on on any Standard plan, in every band, priced with the grid above: a path that pages our on-call for severity 1 only — DNS or DHCP down for a site or a campus. Everything else stays Standard, same-business-day. Premium is the rung above it — the same 24×7 path plus HA architecture review, roadmap input and a closer working relationship. The path opens with Standard, at the same staffing gate, and the education and public-sector discount applies to it like any support plan.
No — and that’s a real difference from commercial DDI, which usually charges a licence for every lab copy too. SpatiumDDI is free wherever you run it: lab, staging, a DR rehearsal, a second copy for training. Spin up as many as you like. A plan covers response on the deployment you name in it; the rest just run.
Yes: 15% off support plans and training for publicly funded institutions — universities, colleges, school boards, hospitals, municipalities and government bodies. Professional services are adjusted by scope rather than by rate. A prepaid term of three to five years takes a further 5%, public buyers can take a five-year fixed-price term instead, and discounts never stack past 40% off list.
Essential agreements are open to early adopters today; Standard has a waitlist and Premium starts with a call. Leave your details and we will come back with a real number — including if the grid above is not the shape you want.
