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 Stirling-PDF?

Stirling-PDF layers MCP and metered AI tools onto its OSS PDF utility, plus a SaaS tier.

Stirling-PDF is shipping fast on its V2 line. The last month splits between heavy engineering — JDK 25 enforcement, a new JPDFium path cutting merge/split memory use by up to 99%, server-side folder storage, desktop multi-window — and a newer direction: an MCP integration page plus pay-as-you-go AI document tools, with stirling.com's SaaS code now folded into the OSS repo. A reworked file-management UI (files left, tools right) addresses long-standing complaints about V2's 'forced file management.' Releases are frequent and several are explicitly flagged WIP.

6.3

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.

S6.3

Stirling-PDF layers MCP and metered AI tools onto its OSS PDF utility, plus a SaaS tier.

◆ Current state

Stirling-PDF is shipping fast on its V2 line. The last month splits between heavy engineering — JDK 25 enforcement, a new JPDFium path cutting merge/split memory use by up to 99%, server-side folder storage, desktop multi-window — and a newer direction: an MCP integration page plus pay-as-you-go AI document tools, with stirling.com's SaaS code now folded into the OSS repo. A reworked file-management UI (files left, tools right) addresses long-standing complaints about V2's 'forced file management.' Releases are frequent and several are explicitly flagged WIP.

◆ Where it's heading

Two arcs are visible in the entries. One is performance and desktop maturity: memory, JDK, multi-window, an auto-updater. The other, newer one is monetizable AI — an MCP page and PAYG-gated AI document and 'AI Create' tools, alongside a SaaS/OSS split the team says it will clarify in coming releases. Stirling-PDF is positioning to be both a self-hosted utility and a hosted, AI-assisted service.

◆ Prediction

Expect the MCP page and AI document tools to move from WIP toward shipped, billed features, and clearer OSS-vs-SaaS release notes as the team separates the two products.
