A Substack alternative that charges per post, not per month
Substack sells a subscription to everything you will write. A sealed post sells one post to the people who want that one, and the rest of your posts stay free.

openmog is not affiliated with Substack; every Substack number below was checked in August 2026 against its published pricing. The two disagree about the unit: Substack prices the writer, by the month; openmog prices the post. What openmog is covers the network around it.
What does a paid subscription actually sell?
Everything, in advance. A paid Substack tier promises the reader all of the writer’s gated posts for as long as the subscription runs, and bills on the calendar whether the month held the best essay of the year or nothing at all. It fits a writer who ships on a schedule to readers who want all of it, and not the writer whose paid-worthy work arrives twice a year, or the reader who wanted one thing.
What does a sealed post do instead?
It sells one post, to the people who want it. A writer writes the post, attaches the payload, and seals it: the tease stays public, the payoff hides behind money. Two modes open a sealed post. Crowdfund sets a goal of $20 to $1,000 and a deadline of one hour to five days; reach the goal and the payload opens for everyone. Pay to reveal sets one price, $5 to $1,000, paid per person, and the post never goes public. How sealed posts work walks the system; your first sealed post is the playbook.
How do the fees compare?
Substack takes 10% of paid subscriptions before card costs, deducted from what the writer earns, as of August 2026; Stripe’s 2.9% and 30 cents, plus 0.7% on recurring charges, come out of the writer’s side too, which is how a $10 subscription lands well under $9. Readers pay no extra on the web, though an iOS in-app subscription can cost more to cover Apple’s commission. openmog’s fee is 10% of each payment with a 75 cent minimum, card processing included, and it sits inside the price the payer sees. Set $30 and the buyer pays $33.34; you receive $30.00. The price you set is the price you receive. On the same $30 from a reader, Substack credits the writer about $25.62 after its 10%, Stripe and the recurring 0.7%, and openmog credits $27.00, its 10% covering card costs. What differs is the order: on openmog you set the amount you receive, the payer sees one all-in number before the card sheet, and nothing comes off afterwards. No monthly plan, no invite code, no follower or impression gate, and no second line for card costs. Credits land as pending, become withdrawable seven days later, and withdrawals start at $50. The FAQ has the rest.
What do the free posts do?
On Substack a free post is marketing for the paid tier: it earns nothing and, once the email is opened or archived, it is done. On openmog a free post is simply a post. It sits in a feed in posting order, collects likes and replies, and stays free: nobody is billed for reading it, and nothing about it changes when you seal the next one. The sealed post is the only thing that costs anyone anything, and only the people who want that one pay for it. That is the whole trade: a writer with a small audience can charge for the piece that deserves it without asking anyone to hold a subscription open through the quiet weeks, and readers who came for the free posts keep getting them. Pay to reveal covers the per-person mode in detail.
What happens when the money does not come?
On Substack the failure mode is slow: subscribers lapse one at a time, and a quiet month still bills the ones who stayed. On openmog, backing places a hold, not a charge. A crowdfund that misses its goal releases every hold in full, and if the creator turned the bonus on and bonders filled the pool, the backers are credited a bonus out of it. Who pays when a post stays sealed walks the mechanism.
Where does Substack still win?
Long-form, the list, and the salary. A five-thousand-word essay belongs on Substack, not in a feed of posts. The subscriber list exports with the writer, and that is a promise openmog does not make: your audience follows you here. The split: run the newsletter on Substack if you have one, and seal the moments, the piece that stands alone, the answer, the ending, as posts, where each one is its own clean transaction and the rest of your writing stays free. Your first sealed post starts one, and the sealed feed shows the ones running now. The full platform landscape places both among their neighbors.
