What Forem does

Forem is an open source software platform that enables the creation and hosting of inclusive online communities, most visibly expressed through its flagship instance DEV Community (dev.to), which reports 3,971,947 members. Built on Ruby on Rails and released under the GNU Affero General Public License, Forem can be self-hosted by any organization or used through managed instances, providing content publishing, discussion forums, user profiles, tagging, video, challenges, and (as of 2025) structured Education Tracks. The product stack is anchored by an Algolia-powered search layer and is complemented by a free Postgres tier through partnership with Neon.

The business model combines an open source distribution strategy with monetization concentrated inside DEV Community. Revenue is primarily generated through advertising and sponsorships — Google AI, Neon, and Algolia are listed as Diamond Sponsors — supplemented by a DEV++ premium subscription tier offering enhanced features, and historically by the DEV Shop merchandise marketplace, which is currently offline for retooling. Customer segments split between individual software developers consuming community content (primary) and organizations seeking to deploy their own Forem-backed community platform (secondary). GTM is community-led and product-led, leveraging open-source adoption, partner sponsorships (e.g., Major League Hacking), and direct presence across Twitter/X, Mastodon, Bluesky, Facebook, Instagram, and Twitch.

To date, Forem has disclosed approximately $12.45M in outside capital across a 2018 seed ($950K, Charge Ventures / Everywhere Ventures) and a 2019 Series A ($11.5M, Mayfield Fund lead with Bossa Invest, OSS Capital, Trousdale Ventures, and XFactor Ventures). Leadership comprises co-founders Ben Halpern, Peter Frank (co-CEO), and Jess Lee. The company is headquartered in New York, operates with 11–50 employees, and serves a global developer audience.

Direct peers

• Circle: Circle is a paid community platform for creators and brands that offers branded communities, discussions, events, and monetization — directly comparable to Forem's hosted community and self-hosting model for organizations building developer/creator communities.
• Discourse: Discourse is an open source discussion and forum platform with a self-hosting/community-edition model very similar to Forem's, commonly deployed for developer and product communities, making it the closest comparable on technology and distribution.
• Mighty Networks: Mighty Networks lets creators and brands build paid branded communities with content, courses, and events — overlapping directly with Forem's community + DEV Education Tracks positioning.
• Hashnode: Hashnode is a developer-focused content and community platform that monetizes via subscriptions and brand partnerships, directly comparable to DEV Community's developer publishing and sponsorship model.
• Ghost: Ghost is an open source publishing and membership platform with a self-hosted/managed offering and creator monetization — comparable to Forem's open source content-and-community model and subscription features like DEV++.
• Bevy: Bevy is a community platform purpose-built for companies running user/developer community programs, with events, chapters, and content — directly comparable to Forem's enterprise self-hosted community use case.

Broad incumbents

• Discord: Discord is a massive-scale communication and community platform widely used by developer communities, offering a much larger but less customizable alternative to Forem's branded community experience.
• Reddit: Reddit operates one of the largest UGC community networks in the world; while not developer-specific, it competes for the same advertising and engagement budgets that flow into developer communities like DEV.
• Slack: Slack is an enterprise collaboration incumbent frequently used as a community/communication layer by developer programs, making it an adjacent incumbent that competes for organizational community spend.

Others

• Substack: Substack is a creator publishing and subscription platform; while not a direct community competitor, it represents the broader ecosystem of creator-monetization tools that overlap with DEV++ subscriptions and Education Tracks.
