Buttondown vs Eleventy: at a glance
What is Buttondown?
Buttondown ships something almost every day, and most of it is somebody's bug report.
Buttondown publishes a dated entry nearly every day, and the mix is dominated by small fixes credited to named users. The feature work in this window is narrow but real: filtered blocks for audience-specific email sections, Mermaid diagram rendering, and enhanced Bluesky link cards. Nothing here changes the product's shape.
What is Eleventy?
The v4 canary line is being renamed Build Awesome while 3.x is kept on pure maintenance.
Two lines run in parallel. The 3.x branch gets dependency-only releases — 3.1.5 and 3.1.6 explicitly ship no core code changes, after 3.1.3 and 3.1.4 failed to publish and were left as immutable dead tags. The v4 alpha train, meanwhile, is where the work is: Node minimum raised to 22.15, page.inputPathDir and page.dir removed, batched incremental builds added, and a large refactor of the Nunjucks fork onto a fully-async prerelease. The releases themselves now carry the Build Awesome name and offer an @awesome.me/buildawesome install alongside @11ty/eleventy@canary.
Buttondown vs Eleventy: editorial side-by-side
Buttondown
5.0MKT AUTO
Buttondown ships something almost every day, and most of it is somebody's bug report.
◆ Current state
Buttondown publishes a dated entry nearly every day, and the mix is dominated by small fixes credited to named users. The feature work in this window is narrow but real: filtered blocks for audience-specific email sections, Mermaid diagram rendering, and enhanced Bluesky link cards. Nothing here changes the product's shape.
◆ Where it's heading
The cadence is the strategy - a steady stream of small corrections keeps the surface tidy rather than betting on a large release. Recent additions cluster around how a publication looks off-platform: Bluesky cards, archive fonts, recognized social links, image handling. Segmentation is the one direction with real room to grow, and filtered blocks is its first visible step.
◆ Prediction
Filtered blocks is the piece most likely to expand, since per-audience content inside a single send invites conditional logic beyond one block type. The daily fix cadence should continue at its current rate.
Eleventy
5.0MKT AUTO
The v4 canary line is being renamed Build Awesome while 3.x is kept on pure maintenance.
◆ Current state
Two lines run in parallel. The 3.x branch gets dependency-only releases — 3.1.5 and 3.1.6 explicitly ship no core code changes, after 3.1.3 and 3.1.4 failed to publish and were left as immutable dead tags. The v4 alpha train, meanwhile, is where the work is: Node minimum raised to 22.15, page.inputPathDir and page.dir removed, batched incremental builds added, and a large refactor of the Nunjucks fork onto a fully-async prerelease. The releases themselves now carry the Build Awesome name and offer an @awesome.me/buildawesome install alongside @11ty/eleventy@canary.
◆ Where it's heading
v4 is accumulating breaking changes faster than it is stabilizing — three of the entries in this window announce removals or minimum-version bumps, and alpha.10 exists only to hotfix a regression alpha.9 introduced. The Nunjucks refactor is the biggest bet: making the fork fully async removes the need for async-specific template tags, but the release notes flag it as risky for existing Nunjucks users. The naming change is proceeding on the same timeline, so users tracking canary are absorbing an identity shift and an API shift at once.
◆ Prediction
Expect more v4 alphas carrying breaking removals before any beta, with the Nunjucks async refactor generating follow-up regressions; 3.x looks likely to keep receiving dependency-only patches with no core changes.
