Fluent Bit vs Stitch: 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 Stitch?
Stitch's November opens the way October ran: one connector fix at a time.
Stitch's recent output is connector maintenance: replication fixes, a Microsoft Advertising move from SOAP to REST, security-driven dependency bumps and SSRF hardening. November so far adds per-contact email activity syncing to the ActiveCampaign connector and a library bump in Harvest. No platform-level change appears in the window.

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.
Stitch
5.0ANALYTICS
Stitch's November opens the way October ran: one connector fix at a time.
◆ Current state
Stitch's recent output is connector maintenance: replication fixes, a Microsoft Advertising move from SOAP to REST, security-driven dependency bumps and SSRF hardening. November so far adds per-contact email activity syncing to the ActiveCampaign connector and a library bump in Harvest. No platform-level change appears in the window.
◆ Where it's heading
The product is in upkeep mode, keeping existing connectors aligned with source APIs and security scans. Additions are small schema extensions rather than new sources or features.
◆ Prediction
More single-connector fixes and dependency bumps are the likely next entries; nothing in the entries points to a platform change.
