Appsmith vs Fiber

Appsmith vs Fiber: 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 Fiber?
Fiber v3 has sat in release candidate for months while v2 gets one-line patches
The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.

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.
Fiber
2.5DEVOPS
Fiber v3 has sat in release candidate for months while v2 gets one-line patches
◆ Current state
The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.
◆ Where it's heading
v3 is the answer to Fiber's longest-standing objection, that building on fasthttp cuts a project off from the net/http middleware ecosystem. Making both handler styles native reframes Fiber as compatible rather than separate. But rc.3 dates to late 2025 and nothing newer has landed in this feed, while v2 patches keep arriving through August — a long release candidate stretch that leaves users choosing between a stable branch in pure maintenance and a v3 that has not been declared final.
◆ Prediction
The next meaningful entry is either a v3.0.0 final or a further RC; until one lands, expect the v2 line to continue receiving single-PR backports and security patches.
