The Story

Substack is a publishing platform where a writer can start a newsletter and charge for it. The platform handles the website, the email delivery, the payment, and the subscriber list, and it takes a cut of subscription revenue rather than charging a monthly fee.

The model is the reason it grew. A writer does not pay for software before earning anything: publishing is free and the platform's revenue comes from the subscriptions it processes. Paid and free subscribers can be on the same list, and a post can be public, free to subscribers, or paid-only.

The tradeoff is control and portability. The audience lives on Substack's network, the design is largely fixed, and the platform's recommendations surface other writers to your subscribers. Writers who want a custom domain, their own design, and an exportable list sometimes move to self-hosted publishing software.

Overview

Substack's commercial model is aligned with the writer's: the platform earns when a subscription is sold, not when software is bought.

A writer starts a publication at no cost. The platform provides the website, the email delivery, the subscriber list, and the payment processing, and it takes a percentage of subscription revenue. Because there is no upfront software cost, publishing a first post requires no financial decision.

Free and paid subscribers share one list, and each post can be public, free to subscribers, or paid-only. That lets a writer build an audience before introducing a paywall, and it lets a paywall apply to some posts rather than all of them.

The tradeoff is control. The audience lives on the platform's network, the design is largely fixed, and the recommendation system surfaces other writers to your subscribers. Writers who want a custom domain, a bespoke design, and a portable list sometimes move to self-hosted publishing software once the audience is established.

Key Features

  • Free publishing

    Starting a publication costs nothing, and the platform earns from subscriptions rather than a software fee.

  • Paid subscriptions

    Payment, recurring billing, and subscriber management are handled by the platform.

  • Mixed free and paid posts

    Each post can be public, free to subscribers, or paid-only, so a paywall can be introduced gradually.

  • Built-in discovery

    A recommendation network surfaces publications to readers, which is a distribution channel a self-hosted site lacks.

Where Substack is a strong choice, and where it is not

Choose Substack when the goal is to start publishing and charging for subscriptions without paying for software first, and the built-in discovery is useful.

Look elsewhere if the publication needs a custom domain with full design control and a portable subscriber list. Self-hosted publishing software offers that at the cost of running it.

Getting started

Publishing the first post takes minutes; growing the list is the ongoing work.

  • ~10 min
    Time to first post

    Create a publication, write, and send. No site setup or hosting is involved.

  • Free
    Cost to start

    Publishing is free. The platform takes a percentage of paid subscription revenue.

  • Nothing
    Prerequisites

    An account. Payment details only if you charge for subscriptions.

Known limitations

Constraints confirmed from the platform's documentation.

  • The audience lives on the platform. The subscriber list is not portable in the way a self-hosted list is.
  • Design control is limited. The publication's appearance is largely defined by the platform.
  • Recommendations surface other writers to your subscribers, which is a growth channel and a distraction.
  • Revenue share applies. The platform takes a percentage of subscriptions rather than a flat fee.
OUR VERDICT

Pick Substack when you want to start publishing without paying first

The commercial model is aligned with the writer: the platform earns when a subscription sells, not when software is bought.

That removes the upfront cost of publishing and makes the first post a zero-risk decision.

If the publication needs a custom domain, full design control, and a portable list, self-hosted publishing software offers that at the cost of running it.

Similar But Scrappier

Notion

FeaturedTrending

Documents, databases, and wikis in one workspace with a shared editor.

Communication & CommunityCCompassPad editorial

Notion is a workspace where documents and databases are the same primitive. A page contains blocks, and a database is a collection of pages with typed properties, which means a task list, a content calendar, and a project tracker are all views over pages rather than separate applications. The product grew by replacing several tools at once: notes, a lightweight wiki, a task board, and a simple database. Because everything shares one editor and one permission model, a team can link a project page to a task database and see the same records from both. Templates and a public gallery spread reusable structures. The tradeoff is depth. A Notion database is not a relational database, so reporting is limited compared with a real BI tool, and large datasets slow down. Teams that push it into that role tend to add a proper database and analytics stack alongside it.

Discord

FeaturedTrending

Voice, video, and text channels organised into servers.

Communication & CommunityCCompassPad editorial

Discord is a communication platform organised around servers, each containing channels. A channel is text, voice, or a forum, and permissions are set per role, so a server can be private to a team or open to a large community with the same primitives. The product began in gaming and spread because the combination of always-available voice and persistent text suited any group that spends time together online. Voice channels are joinable without a call being placed, which removes the scheduling step that a meeting tool requires. Screen sharing and video are available in the same channel. For communities, the platform provides moderation tooling, role-based access, and bots that extend a server with automation. The tradeoff is that history and membership live in a vendor's account rather than on infrastructure the community controls, and the interface is optimised for live presence rather than for durable documentation.

Slack

Channel-based messaging with an app platform for workplace workflows.

Communication & CommunityCCompassPad editorial

Slack is a messaging platform for organisations, organised around channels. A channel is a named conversation that can be public, private, or shared with an external organisation, and membership is a deliberate act rather than an accident of a contact list. The structure is what distinguishes it from a group chat. Threads keep a reply attached to its parent, so a channel is not consumed by a side conversation. Search covers message history and files, and a shared channel lets two organisations work in the same space without exchanging accounts. The platform's second half is the app directory and workflow builder. Incoming webhooks, slash commands, and bots let an external system post into a channel or accept a command from one, which is how alerts and approvals end up where a team already is. The cost is per-seat pricing and the fact that an organisation's conversation history lives in a vendor account.
