What is Bunny.net?
Bunny.net is sprinting on edge breadth — AVIF, API Guardian, seamless migration, and Stream API ergonomics in two weeks.
Bunny.net shipped a heavy April-into-May batch across its full surface area: AVIF input/output in the image Optimizer, image upscaling with resampling, seamless domain migration with DNS-verified SSL, and a new Stream 'Add video library' API endpoint that pre-configures encoding, transcribing, and resolutions in one call. Just outside the recent-six window, API Guardian (April 27) added schema-aware OpenAPI enforcement at the edge inside Bunny Shield. The cadence and breadth is closer to a hyperscaler than a niche CDN.
What is NATS?
NATS 2.15 introduces a desired-state reconciliation engine for JetStream, making cluster operations safe to run mid-flight.
NATS is in the RC phase for v2.15, which centers on a new desired-state metalayer for JetStream — a reconciliation engine that makes stream and consumer placement changes safe to execute during ongoing operations. Cancelling in-flight scale/move operations, changing replication factors mid-move, and peer-removing are all significantly safer. The parallel v2.14.7 release backports metalayer compatibility and fixes a set of JetStream data races and consumer state bugs identified during 2.15 testing.

Bunny.net
6.3DEVOPS
Bunny.net is sprinting on edge breadth — AVIF, API Guardian, seamless migration, and Stream API ergonomics in two weeks.
◆ Current state
Bunny.net shipped a heavy April-into-May batch across its full surface area: AVIF input/output in the image Optimizer, image upscaling with resampling, seamless domain migration with DNS-verified SSL, and a new Stream 'Add video library' API endpoint that pre-configures encoding, transcribing, and resolutions in one call. Just outside the recent-six window, API Guardian (April 27) added schema-aware OpenAPI enforcement at the edge inside Bunny Shield. The cadence and breadth is closer to a hyperscaler than a niche CDN.
◆ Where it's heading
Bunny.net is staying the affordable alternative to Cloudflare and Fastly while matching feature breadth release-by-release. The trajectory keeps adding capabilities up the stack — first CDN, then image optimization, then video streaming, now API security and zero-downtime migration. Each addition is a reason to consolidate workloads on Bunny instead of stitching multiple vendors. Expect continued pressure on the edge incumbents from below.
◆ Prediction
Watch for AI-related edge primitives — model-serving at the edge, AI inference workers — that would put Bunny.net into Cloudflare Workers AI territory. The Stream API expansion suggests video AI (auto-transcription, scene detection) is also imminent.
NATS
7.5DEVOPS
NATS 2.15 introduces a desired-state reconciliation engine for JetStream, making cluster operations safe to run mid-flight.
◆ Current state
NATS is in the RC phase for v2.15, which centers on a new desired-state metalayer for JetStream — a reconciliation engine that makes stream and consumer placement changes safe to execute during ongoing operations. Cancelling in-flight scale/move operations, changing replication factors mid-move, and peer-removing are all significantly safer. The parallel v2.14.7 release backports metalayer compatibility and fixes a set of JetStream data races and consumer state bugs identified during 2.15 testing.
◆ Where it's heading
The desired-state metalayer is an architectural addition that addresses a real operational risk: JetStream's previous behavior required careful sequencing of cluster topology changes to avoid data loss or inconsistent state. The pattern across recent releases — isolated stream read locks, constant-time removal from service maps, reduced client buffer flushing — shows a systematic performance and correctness pass across JetStream at high scale. NATS is moving toward the safety properties needed for production-critical stateful messaging.
◆ Prediction
v2.15.0 GA will likely ship within weeks of RC.2. The next cycle will probably extend desired-state semantics to more JetStream operations and potentially introduce observability tooling around reconciliation state, giving operators visibility into in-progress cluster changes.
