About
EchoRelay is a managed runtime for custom API integrations.
Describe one integration once: what comes in, the target system, credentials, the retry policy, and how the answer maps back. EchoRelay validates each inbound request, maps it, replies synchronously, passes streams through, fans out to multiple targets, or queues delivery with automatic retry, a dead-letter queue and replay.
Every configuration change is versioned. Preview, diff, dry run, schedule, publish and roll back. When a vendor changes their API or rotates a credential, you update the configuration and publish. Deploy nothing.
Build and operate each integration through the REST API, an MCP server so an AI agent can do the wiring, or the web panel. Free to start, no card required.

About
Postproxy replaces a dozen platform-specific integrations with a single REST endpoint. Send one request with your content and target profiles, and Postproxy handles format conversion, OAuth, token refresh, rate limits, retries, and per-platform delivery — returning structured outcomes for each network. Beyond publishing, it manages post comments, direct messages, replies to Google Business reviews, and pulls profile and follower stats, covering the full posting lifecycle through one API.
It supports Instagram, Facebook, Threads, TikTok, X, YouTube, LinkedIn, Pinterest, Bluesky, Telegram, and Google Business, with Reddit coming soon. Official SDKs cover TypeScript, Python, Ruby, Go, Java, .NET, and PHP, plus webhooks, an MCP server for AI agents, and integrations with n8n, Zapier, Make, and Needle. Built for SaaS, automation pipelines, and agencies. EU-hosted and GDPR-compliant. Free tier, no credit card required.
