Free and Pro
Free includes one blog, unlimited posts, 50 MB of image uploads, themes, custom CSS, built-in variables and Obsidian publishing.
Pro adds up to five blogs, 5 GB of shared image storage, larger uploads and quality controls, detailed analytics, custom domains, password protection, custom variables, optional branding and replies as your blog.
Some accounts have a larger Free allowance from an earlier offer or promotion. Your dashboard shows your actual allowance. Use a promotion link or code as instructed by the offer; storage offers and checkout discounts can have different terms.
If Pro ends, your writing stays in place. Existing passwords and saved custom variables keep working. Paid tools become available again when Pro is active; you may need to upgrade or free space before uploading more images.
