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

Failed payments are the silent MRR killer for subscription SaaS, Stripe retries the card, but nobody tells the customer to fix it. RetryFi closes that gap. It connects to your Stripe account with OAuth in seconds, RetryFi only reads your billing data and retries failed invoices; it never creates charges or modifies your Stripe data. It then runs an opinionated, branded four-email dunning sequence that's aware of the decline code: soft declines get smart retries, hard declines skip straight to a "fix your card" email with a one-click update link. You get a recovery dashboard and a 90-day historical scan of what you've already lost. Built for indie and bootstrapped SaaS on Stripe, free up to 10 recoveries a month, no platform price tag.
