The short version

  • Only CouchDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: Canary Labs pricing steps by tag band rather than actual tags, so a site sitting just above a threshold pays the next band in full; growth from 3,400 to 3,600 tags is a licence purchase, not a rounding error.; CouchDB append-only storage model may have performance implications for certain workloads with high update rates
  • They diverge on capability: Canary Labs covers Loss-less compression, CouchDB covers Multi-master Replication.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Canary Labs

  • Pricing steps by tag band rather than actual tags, so a site sitting just above a threshold pays the next band in full; growth from 3,400 to 3,600 tags is a licence purchase, not a rounding error.
  • CustomerCare at 18 percent of licence cost is effectively mandatory on perpetual licences because lapsing it removes upgrades, so the perpetual option is not really a one-time cost.
  • The storage format is proprietary; getting data out at volume means the ODBC connector, an additional 2,500 USD one-time or 1,000 USD a year, or writing against the REST API.
  • Canary is a small vendor with a limited partner network outside North America, so support coverage and integrator availability in Europe and Asia are thinner than for AVEVA or Ignition.
  • It is a Windows-only server product with no Linux or container deployment, which complicates placing collectors in modern edge estates.

CouchDB

  • Append-only storage model may have performance implications for certain workloads with high update rates
  • Requires network synchronisation for cluster data consistency; can introduce latency in multi-master scenarios
  • No explicit support for complex joins; MapReduce queries may be inefficient compared to relational databases

Answered from the vendors’ own pages

Canary Labs: What does Canary cost?

8,730 USD for a 3,500 tag perpetual system including first-year CustomerCare, or 3,000 USD a year on subscription.

CouchDB: Is Apache CouchDB free to use?

Yes, Apache CouchDB is completely free to download and use. It is open source software licensed under the Apache License 2.0.

CouchDB: Can I use CouchDB for commercial purposes?

Yes, the Apache License 2.0 permits commercial use. The license is permissive and does not restrict business applications.

Canary Labs: Is perpetual cheaper than subscription?

Canary states perpetual pays off after roughly three years, and after that you still pay 18 percent CustomerCare annually.

CouchDB: Is there a paid support or professional services option?

CouchDB's homepage mentions Professional Services as an available option, but no pricing details or specific service costs are listed. Contact the Apache CouchDB project for more information.

Source
Canary Labs: Does it use lossy compression?

No. Canary stores every collected value rather than approximating the trend, which matters for regulated data retention.

CouchDB: Who handles hosting costs if I use CouchDB?

CouchDB is self-hosted, so you are responsible for your own infrastructure and hosting costs. The software itself is free.
