Appsmith vs Bun: 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 Bun?
Bun rewrote its entire runtime from Zig to Rust and shipped HTTP/2 server support in v1.4.
Bun made two foundational moves in 2026: a complete Zig-to-Rust rewrite announced in July, and a v1.4.1 release that ships HTTP/2 server support in Bun.serve, workspace-scoped node_modules, argon2 in crypto, tree-shaking through dynamic imports, and a 9x throughput gain on Buffer I/O. The runtime now handles most production server workloads that previously required Node.js.

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.
Bun
5.0DEVOPS
Bun rewrote its entire runtime from Zig to Rust and shipped HTTP/2 server support in v1.4.
◆ Current state
Bun made two foundational moves in 2026: a complete Zig-to-Rust rewrite announced in July, and a v1.4.1 release that ships HTTP/2 server support in Bun.serve, workspace-scoped node_modules, argon2 in crypto, tree-shaking through dynamic imports, and a 9x throughput gain on Buffer I/O. The runtime now handles most production server workloads that previously required Node.js.
◆ Where it's heading
Bun is methodically closing Node.js compatibility gaps while building APIs Node.js does not have — Bun.Image, Bun.cron, Bun.WebView, HTTP/2+3 support. The Rust rewrite signals long-term commitment to safety and contributor ecosystem depth that Zig could not provide. At this pace, a v2.0 major is the next logical milestone to formalize the built-in API surface.
◆ Prediction
A 2.0 major release will likely stabilize the HTTP/2 and HTTP/3 server story and formalize the Bun.Image and Bun.cron APIs as supported. The Rust migration should produce measurably lower crash rates in subsequent releases.
