Fluentd vs ToolJet
A side-by-side editorial comparison of Fluentd and ToolJet — release velocity, themes, recent moves, and the top alternatives to consider.
Fluentd vs ToolJet: at a glance
What is Fluentd?
Fluentd's newest line spent its last release hardening the paths that accept untrusted data.
Two branches are live: 1.19.x carries features and 1.16.x takes occasional single-fix backports. The most recent 1.19.3 is a dense correctness release with a distinctly security-shaped batch — strict host validation for dynamic endpoints in out_http, size limits enforced on decompressed payloads in the buffer and HTTP input, strict path boundary validation for tags, and tightened default visibility for config, retry and debug information in the monitor agent.
What is ToolJet?
ToolJet ships AI Builder release 4 to its LTS line, with Gemini 4 Argon support.
ToolJet's LTS v3.20.250 brings AI Builder release 4 into the enterprise edition, with cancellation handling and Gemini 4 Argon as a model option; v3.20.248 added workspace MCP OAuth with SSO login. The beta line spent the week on Node 22.23.4 for the October security release, file-permission and license-check fixes, a page-panel crash fix, and an environment flag that limits ToolJet Database edits to admins.

Fluentd's newest line spent its last release hardening the paths that accept untrusted data.
◆ Current state
Two branches are live: 1.19.x carries features and 1.16.x takes occasional single-fix backports. The most recent 1.19.3 is a dense correctness release with a distinctly security-shaped batch — strict host validation for dynamic endpoints in out_http, size limits enforced on decompressed payloads in the buffer and HTTP input, strict path boundary validation for tags, and tightened default visibility for config, retry and debug information in the monitor agent.
◆ Where it's heading
The feature work landed in 1.19.0 — zstd compression across buffer, out_file, out_forward and in_forward, chunk evacuation when the retry limit is hit, TLS 1.3 in out_http — and everything since has been reliability and input validation. That ordering makes sense for a log collector: the interesting failure modes are decompression bombs, path traversal through tag names, and sockets that never close, not missing features. Ruby 4.0 compatibility work is threaded through the recent releases.
◆ Prediction
Expect 1.19.x to keep shipping validation and socket-lifecycle fixes with Ruby 4.0 support consolidating, and 1.16.x to receive only isolated backports.
ToolJet
5.0INFRA · APIS
ToolJet ships AI Builder release 4 to its LTS line, with Gemini 4 Argon support.
◆ Current state
ToolJet's LTS v3.20.250 brings AI Builder release 4 into the enterprise edition, with cancellation handling and Gemini 4 Argon as a model option; v3.20.248 added workspace MCP OAuth with SSO login. The beta line spent the week on Node 22.23.4 for the October security release, file-permission and license-check fixes, a page-panel crash fix, and an environment flag that limits ToolJet Database edits to admins.
◆ Where it's heading
The AI Builder work that sat in beta is now reaching LTS customers, alongside MCP connections that respect SSO. Most other changes on both lines are security bumps and hardening, which fits a product selling to enterprises that run the LTS track.
◆ Prediction
Expect AI Builder to keep adding models and EE controls on LTS, and more admin-level permission flags like the database-edit restriction.
