Cert Decoder
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.
Cert Decoder is a free online tool that helps you decode X.509 SSL/TLS certificates in PEM format. It instantly shows important information like the issuer, expiry date, SAN entries, and fingerprint. All data is processed locally in your browser, so nothing is ever sent or stored elsewhere.

Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
RetryFi's answer
Next.js (React 19, TypeScript) front and back, Supabase (Postgres) for data and auth, the Stripe API via Connect/OAuth for billing, Inngest for the durable retry and dunning workflows, Resend + React Email for the branded emails, Recharts for the dashboard, and Tailwind CSS for the UI.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
RetryFi's answer
Indie and bootstrapped SaaS founders running subscriptions on Stripe — usually solo or small teams losing recurring revenue to failed payments, who don't want an enterprise dunning platform or a tool that skims a percentage of what it recovers.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
RetryFi's answer
Most failed-payment tools fire generic retries or take a percentage of recovered revenue. RetryFi does neither. You get a branded, decline-code-aware sequence sent under your own name and logo, a recovery dashboard, and a 90-day historical scan of what you've already lost — set up in seconds with Stripe OAuth, no code. It's built and priced for indie SaaS: free up to 10 recoveries a month, flat $29 and $79 tiers above that, never a cut of your revenue.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

RetryFi's answer
RetryFi is opinionated about why a payment failed. It reads the Stripe decline code and reacts: soft declines (insufficient funds, generic) get smart retries, while hard declines (expired or lost card) skip retries and go straight to a branded "fix your card" email with a one-click update link. It runs alongside Stripe's own retries as a single branded sequence — no generic Stripe notices, no platform price tag, and no percentage cut of what you recover.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
