What is Dragonfly?

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

What is Chromatic?

Chromatic opens a beta that lets coding agents read and fix visual test failures.

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

Dragonfly vs Chromatic: editorial side-by-side

D
Dragonfly
INFRA · APIS
5.0

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

◆ Current state

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

◆ Where it's heading

Dragonfly is maturing for production operations: the 2.0 line fixed cluster correctness, and 2.1 starts by making replication and persistence observable from Prometheus. The project says it prefers small incremental features, so 2.1 will likely grow the same way.

◆ Prediction

More metrics and cluster-mode fixes on 2.1, with 1.40 and 2.0 still getting backports for a while.

7.5

Chromatic opens a beta that lets coding agents read and fix visual test failures.

◆ Current state

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

◆ Where it's heading

Chromatic is turning from a review screen for humans into a feedback loop that coding agents can act on. Each new entry point (Vitest, React Native, now agents) widens who and what sends work through its visual tests.

◆ Prediction

The beta post is brief, so how agents connect is unclear; expect a follow-up naming the supported agents and moving this toward general availability.
