Instatic: A Self-Hosted Visual CMS That Publishes Plain HTML and CSS
Instatic is an open-source, self-hosted CMS from the CoreBunch team that packs a canvas editor, content management, forms, plugins and a publisher into one Bun server. Published pages are plain HTML and CSS with no framework runtime, a good fit for indie developers and small teams who want off Webflow's monthly bill but find WordPress too heavy.
