About letmepost.dev
What is letmepost.dev?
letmepost.dev is an open-source social media publishing API that allows developers to send a single request to publish content across multiple platforms like X, Bluesky, and Pinterest. Instead of integrating with each platform individually, you use one endpoint and receive structured outcomes for every target. It's built like infrastructure—with preflight validation, idempotent writes, and a reviewed app of record—so you can focus on your product rather than platform quirks.
Who is it for?
letmepost.dev is ideal for indie SaaS developers, agencies managing multiple client accounts, and teams building social automation tools. It's built for developers who need reliable, scalable social posting without the overhead of maintaining separate integrations. If you're a solo developer or a small team that wants to publish programmatically to social media, this tool saves weeks of integration work and ongoing maintenance.
Real use cases
Use letmepost.dev to automate cross-posting from your app, schedule content across platforms, or manage social presences for multiple clients. It's also great for AI agents that need to post updates on behalf of users. The flat per-org pricing (no per-profile or per-seat fees) makes it cost-effective for agencies and high-volume publishers.
What it's not for
letmepost.dev is not for non-technical marketers who want a ready-made social media scheduler. It's an API-first tool, so you'll need some coding ability to integrate it into your workflow. If you're looking for a no-code social media management dashboard, this isn't it.
Key features
- Multi-target publishing — Send one request to publish to X, Bluesky, Pinterest, and more, with structured per-target results.
- Preflight validation — 80 rules run locally to catch errors before they hit the platform, with clear error codes and docs.
- Idempotent writes — Retry safe, thanks to Idempotency-Key support; retries return cached responses for 24 hours.
- Reviewed app of record — letmepost.dev is the reviewed app for Meta and LinkedIn, so you can publish through approved OAuth flows.
- Open source — Apache-2.0 license; self-host for free with the same image as hosted.
- Flat per-org pricing — No per-profile or per-seat fees; you only pay for posted volume.
- Webhooks and scheduling — Full API surface includes scheduling, cancellation, and webhook events.
