Demand for unregistered services
The evidence behind DevCloud’s coverage target.
Sampled 2026-09-05; re-derive with python3 scripts/demand_rank.py.
What this measures
DevCloud has no usage telemetry, so this page does not measure what its users ask for. It measures revealed demand: how many of three independent projects have already built each AWS service DevCloud does not register. Each serves a population DevCloud names as its own, and each only adds a service when somebody asks.
| Source | What it is | Services | Unmatched names |
|---|---|---|---|
| moto | Python AWS mocking library — boto3 developers running tests | 163 | 0 |
| LocalStack | Local AWS emulator; community + pro | 119 | 4 |
| terraform-provider-aws | One Go package per service — the IaC population | 273 | 4 |
Read a high support count as this service is worth emulating to someone, not as
our users want this. The live measurement of DevCloud’s own traffic is
GET /devcloud/api/unrouted, which accrues behind this page; its ceiling is in
coverage.md.
“Unmatched names” is the join diagnostic: a name a source publishes that matches neither the missing set nor a registered service. A large number there would mean name normalisation is dropping matches and the support counts are too low.
Readings
| Reading | Value |
|---|---|
| Upstream model files | 431 |
| Registered when sampled | 148 |
R1 — missing set M | 283 |
R2 — M with support 3 | 8 |
R2 — M with support 2 | 49 |
R2 — M with support 1 | 111 |
R2 — M with support 0 | 115 |
R2 — M with support ≥ 2 | 57 (20.1% of M) |
Full ranking
Ordered by support count, then name — the order the work was done in, so stopping at any point would have stopped on the best surface available.
All 57 services with support ≥ 2 are registered, down to and including
workspaces-web; TestDemandSetIsRegistered fails if any of them stops being.
56 serve at least one operation, and the one that does not (rds-data) is named
with its reason in coverage.md. Everything below them — support 1
and support 0 — is the 226 services that carry no depth commitment. They are
registered and engine-served, so a call to one is answered locally rather than
billed; what this study declined to promise is that it is answered faithfully.
