NSD vs Aiven
A side-by-side editorial comparison of NSD and Aiven — release velocity, themes, recent moves, and the top alternatives to consider.
NSD vs Aiven: at a glance
What is NSD?
NSD's 4.15 line is being shaped by outside researchers' bug reports.
NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.
What is Aiven?
Aiven moves Grafana to 13 and gives Runtime apps custom domains.
Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.

NSD
5.0DEVOPS
NSD's 4.15 line is being shaped by outside researchers' bug reports.
◆ Current state
NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.
◆ Where it's heading
Most of the 4.15 cycle is reactive: four security or bug-fix releases since August, with outside researchers finding parser overflows, crashes on malformed catalog zones and IXFR edge cases. Features still arrive, and at least one, catalog-group-pattern, was suggested by a researcher who also reported bugs. Catalog zones and zone-file parsing are where the attention is concentrated.
◆ Prediction
Expect more fixes in catalog zone and zone-file parsing as outside fuzzing continues, likely in another 4.15 patch. The entries give no sign of a 4.16 feature release.
Aiven
6.3DEVOPS
Aiven moves Grafana to 13 and gives Runtime apps custom domains.
◆ Current state
Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.
◆ Where it's heading
Aiven is filling out the layer around its databases: logs, access control, encryption, dashboards and now an application runtime with its own domains. Each release is small, but together they make it easier to keep both data and the apps that use it on Aiven.
◆ Prediction
Expect more Aiven Runtime features that connect apps to Aiven's own databases, and a default-version switch to Grafana 13 once 12.4 nears end of support.
