Self-hostable open-source platforms that AI builders run as part of their stack — Postgres-based databases (Supabase), workflow automation (n8n), analytics (PostHog, Plausible), BI (Metabase), CMS, communication, and similar. All are open-source and have meaningful AI features or are foundational to AI products.
AI builders pick more than just an agent — they assemble a full stack. Listing the OSS backbone next to the agent layer keeps RepoDepot a single map of what serious builders actually run.
