About
PostLake is a unified social media API for developers, product teams, and AI agents. Connect your accounts once, then publish, schedule, and measure content from one place — dashboard, REST API, or MCP — with a consistent response shape your software can rely on.
Agent-first by design: built for systems that need to post safely and reliably, with clear errors, sensible retries, and normalised analytics so you (or an agent) can decide what to publish next. We keep expanding networks and capabilities as an improving platform, not a fixed list of destinations.
Create an account, connect the profiles you own, upload media, and publish or schedule. Stay in control — disconnect anytime; we only act on accounts and content you choose. We do not sell your data or use your posts to train AI models.
Whether you ship an agent, automate multi-channel publishing, or add social posting to your product, PostLake sits between your software and the social web.
