Answer

Run a Stack Overflow of your own: Apache Answer brings the question-and-answer format in-house, maintained under the Apache Software Foundation with an Apache-2.0 license. You use it to run a community forum, product help center, or internal knowledge base where content lives as questions and answers rather than wiki pages. It ships the mechanics that make that format work: voting, accepted answers, a reputation system with privilege levels, tagging, full-text search with filters, revision history on every edit, and admin/moderator/user roles. Content is written in Markdown with real-time preview and code syntax highlighting. A plugin system covers OAuth login (Google, GitHub), S3 storage, external search backends like Algolia, and Akismet anti-spam, and a REST API exposes platform data for integration. The backend is Go, the frontend React, and it runs against SQLite, MySQL, or PostgreSQL. Self-hosting replaces per-seat tools like Stack Overflow for Teams with a flat-cost instance where you own all the content.

Benefits

  • Knowledge That Stays Findable
  • The question-and-answer format with tags, voting, and accepted answers surfaces solutions better than chat threads or wiki sprawl. Repeated questions get answered once and found by search afterward.
  • No Per-Seat Pricing
  • Stack Overflow for Teams and similar products charge per user per month. A self-hosted Answer instance supports unlimited users and unlimited content for the cost of hosting.
  • Community Self-Moderation
  • Reputation earned through upvotes unlocks privileges progressively, so trusted members handle editing and moderation, reducing the load on admins as the community grows.
  • Apache Foundation Governance
  • The project is maintained under the ASF with an Apache-2.0 license, giving it neutral governance, a business-friendly license, and a lower risk of a rug-pull relicensing than single-vendor projects.

Features

  • Voting, Reputation, and Accepted Answers
  • Upvotes and downvotes rank content, accepted answers mark solutions, and reputation gates privileges like editing and moderation.
  • Markdown Editor with Live Preview
  • CommonMark-compatible Markdown with side-by-side real-time preview and code syntax highlighting for technical content.
  • Tagging and Advanced Search
  • Organize content with tags and search with filters by tag, user, and score. Real-time suggestions surface similar existing questions as users type, cutting duplicates.
  • Roles and Revision History
  • Admin, moderator, and user roles control access. Every edit to questions, answers, and tags is versioned with a transparent revision history.
  • Plugin System
  • Community plugins add third-party OAuth login, object storage, external search engines, caching, and anti-spam without modifying core code.
  • 40+ Languages and Responsive UI
  • Community-translated language packs, mobile-friendly responsive layout, dark mode, and customizable themes for brand alignment.
