Buttondown vs Craft CMS: at a glance
What is Buttondown?
Buttondown closes an API send loophole and blocks confirmation-email floods in its daily fixes.
Buttondown is a newsletter platform run on a daily-changelog cadence of small fixes. Over the last week it added sign-in limits, two-factor lockouts and auto-disabled failing webhooks, then closed a gap where API keys without sending access could still send through POST /v1/emails. It also stopped bots from signing one inbox up to many newsletters at once, and raised text contrast in light and dark mode.
What is Craft CMS?
Craft CMS 6.0 is a full Laravel rewrite — alpha releases are shipping breaking API changes every week.
Craft CMS 6.0 is mid-alpha, with a complete architectural shift from Yii to Laravel as its foundation. The alpha cadence has been weekly or better, each release removing legacy event-based APIs and replacing them with modern Laravel patterns — service containers, Artisan commands, Inertia/Vue CP pages. Image handling was overhauled to intervention/image with libvips support and new format coverage (HEIC, JPEG XL). The 5.x line continues receiving security and bug patches in parallel.

Buttondown
5.0MKT AUTO
Buttondown closes an API send loophole and blocks confirmation-email floods in its daily fixes.
◆ Current state
Buttondown is a newsletter platform run on a daily-changelog cadence of small fixes. Over the last week it added sign-in limits, two-factor lockouts and auto-disabled failing webhooks, then closed a gap where API keys without sending access could still send through POST /v1/emails. It also stopped bots from signing one inbox up to many newsletters at once, and raised text contrast in light and dark mode.
◆ Where it's heading
The daily polish is running on two tracks: account and API security (rate limits, 2FA lockout, API key permissions, abuse protection) and accessibility (screen-reader support, keyboard navigation, now contrast). Both point at a product being hardened for larger and more compliance-sensitive senders, not at new features.
◆ Prediction
Expect more permission and abuse fixes alongside further accessibility passes, still shipped as daily batches of small fixes.
Craft CMS
5.0MKT AUTO
Craft CMS 6.0 is a full Laravel rewrite — alpha releases are shipping breaking API changes every week.
◆ Current state
Craft CMS 6.0 is mid-alpha, with a complete architectural shift from Yii to Laravel as its foundation. The alpha cadence has been weekly or better, each release removing legacy event-based APIs and replacing them with modern Laravel patterns — service containers, Artisan commands, Inertia/Vue CP pages. Image handling was overhauled to intervention/image with libvips support and new format coverage (HEIC, JPEG XL). The 5.x line continues receiving security and bug patches in parallel.
◆ Where it's heading
Every alpha release trades backward compatibility for a cleaner platform foundation. Plugin authors are absorbing breaking changes in batches, with a compatibility shim (yii2-adapter) as the bridge. The CP frontend is moving steadily to Inertia/Vue, and the fluent component APIs suggest a design system consolidation. Once the alpha phase closes, Craft 6 will require full plugin rewrites — the ecosystem disruption is the price of the architectural cleanup.
◆ Prediction
The next alpha releases will focus on stabilizing the plugin API surface and filling gaps in the Inertia/Vue CP migration. A beta tag is plausible within 2-3 months if the breaking-change cadence slows. Expect the yii2-adapter compatibility layer to become a first-party migration guide rather than a long-term support path.
