Appsmith vs NSD: at a glance
What is Appsmith?
Appsmith is killing its own AI datasource and doubling down on security hardening — a strategic retreat from the AI feature race.
Appsmith crossed the 2.0 milestone in 2026, bundling MongoDB 7 and completing a multi-release security hardening arc. The most strategically notable move is the EOL of Appsmith AI: as of September 30, 2026, the built-in AI datasource stops working entirely. New connections were blocked starting in v2.3, and v2.4 is the final reminder before the cutoff. The v2.4.1 security release — Databricks JDBC URL validation, CVE patch, and WHERE-clause column name sanitization in UQI filtering — shows the product is used in real enterprise environments with sensitive data.
What is NSD?
NSD patched 8 CVEs across two dedicated security releases and added EDNS0 padding and PROXYv2 access controls.
NSD released three significant versions in quick succession: 4.15.1 fixed four CVEs including a TCP-window-throttle DoS, a UDP cookie-option DoS, an IP ACL bypass for some address ranges, and a PROXYv2 port ACL bypass. 4.15.2 followed with feature additions — HHIT/BRID RR type support, new SVCB service parameter keys (docpath, pvd, oots), EDNS0 padding over TLS per RFC 7830/8467, and configurable PROXYv2 access control — alongside another substantial round of hardening fixes, many reported by Palo Alto Networks. The 4.15.0 release introduced a breaking change to Prometheus metrics, moving zone names from metric labels to label values.

Appsmith is killing its own AI datasource and doubling down on security hardening — a strategic retreat from the AI feature race.
◆ Current state
Appsmith crossed the 2.0 milestone in 2026, bundling MongoDB 7 and completing a multi-release security hardening arc. The most strategically notable move is the EOL of Appsmith AI: as of September 30, 2026, the built-in AI datasource stops working entirely. New connections were blocked starting in v2.3, and v2.4 is the final reminder before the cutoff. The v2.4.1 security release — Databricks JDBC URL validation, CVE patch, and WHERE-clause column name sanitization in UQI filtering — shows the product is used in real enterprise environments with sensitive data.
◆ Where it's heading
The AI datasource retraction, combined with the security hardening trajectory, suggests Appsmith is choosing depth over breadth: a more trustworthy, auditable low-code platform rather than a feature-competitive one. The Databricks JDBC integration and the UQI SQL injection fix signal that enterprise data sources are increasingly in scope. The v2.x series has consistently prioritized SSRF protection, access control enforcement, and CVE remediation.
◆ Prediction
Future releases will likely expand the data connector library (Databricks is now validated) and continue the security hardening pattern; the AI gap will be filled by first-party connector support for external AI services rather than a built-in model.
NSD
5.0DEVOPS
NSD patched 8 CVEs across two dedicated security releases and added EDNS0 padding and PROXYv2 access controls.
◆ Current state
NSD released three significant versions in quick succession: 4.15.1 fixed four CVEs including a TCP-window-throttle DoS, a UDP cookie-option DoS, an IP ACL bypass for some address ranges, and a PROXYv2 port ACL bypass. 4.15.2 followed with feature additions — HHIT/BRID RR type support, new SVCB service parameter keys (docpath, pvd, oots), EDNS0 padding over TLS per RFC 7830/8467, and configurable PROXYv2 access control — alongside another substantial round of hardening fixes, many reported by Palo Alto Networks. The 4.15.0 release introduced a breaking change to Prometheus metrics, moving zone names from metric labels to label values.
◆ Where it's heading
NSD is in a security-intensive maintenance phase with a consistent external contributor: Qifan Zhang at Palo Alto Networks has reported the majority of bugs fixed in the 4.15.x cycle, including heap overflows, assertion failures on malformed records, and multiple DoS vectors. This external security research pressure is accelerating the quality of NSD's defensive posture. Protocol completeness work (new RR types, SVCB parameters) continues alongside the security fixes.
◆ Prediction
The PROXYv2 improvements suggest NSD deployments behind TLS-terminating load balancers are a growing use case — expect additional configuration controls for encrypted-DNS setups. The experimental multi-catalog-consumer-zones flag may graduate to stable in a future release.
