Fluent Bit vs HyperDX: at a glance
What is Fluent Bit?
Fluent Bit 5.2 adds its own typed scripting language for log processing
Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.
What is HyperDX?
HyperDX's CLI connects AI coding agents to your logs with one command.
HyperDX 2.44, published under the ClickStack name, adds `hdx mcp install`, which checks an API key with hidden input and registers the ClickStack MCP server in Claude Code, Codex, Cursor and VS Code. The release also adds team-owned API keys that survive their creator leaving, conditional ad hoc dashboard filters, a working Denoise option, and collector seeds with session ID columns and ZSTD(3) compression. The app's own telemetry moved to the ClickStack SDKs and stable OpenTelemetry semantic conventions.

Fluent Bit 5.2 adds its own typed scripting language for log processing
◆ Current state
Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.
◆ Where it's heading
After a month of hardening on 5.1, the 5.2 line puts new surface on top: a typed transform language that also runs in the browser build. Fluent Bit is moving from a collector configured with Lua snippets toward an agent with its own checked policy format.
◆ Prediction
Expect 5.2.x patch releases soon fixing regressions in the new FTS processor, and more FTS policy packs; the browser SDK is likely to stay labelled experimental for now.
HyperDX
5.0ANALYTICS
HyperDX's CLI connects AI coding agents to your logs with one command.
◆ Current state
HyperDX 2.44, published under the ClickStack name, adds `hdx mcp install`, which checks an API key with hidden input and registers the ClickStack MCP server in Claude Code, Codex, Cursor and VS Code. The release also adds team-owned API keys that survive their creator leaving, conditional ad hoc dashboard filters, a working Denoise option, and collector seeds with session ID columns and ZSTD(3) compression. The app's own telemetry moved to the ClickStack SDKs and stable OpenTelemetry semantic conventions.
◆ Where it's heading
HyperDX is folding into the ClickStack brand and making AI agents a first-class consumer of its data, with key setup moving from copied snippets to a CLI flow. Session replay and OpenTelemetry alignment, started in 2.43, continue at the schema level.
◆ Prediction
Expect the remaining HyperDX package and repository names to switch to ClickStack, following the moved GitHub links, image name and SDKs in this release.
