As answered by people managing Cert Decoder and BuzzWire.
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.
BuzzWire's answer:
A solo founder watched creators get squeezed from two directions at once in 2026: ManyChat cut its free tier from 1,000 contacts to 25 and moved to per-contact billing, while Meta cut the DM rate cap from 5,000/hour to 200/hour during the largest suspension wave the platform has seen. Every automation tool responded with reassuring blog posts. BuzzWire was built to respond with architecture — a tool that enforces the platform's real limits by default, stays free without metering, and tells creators the truth about platform risk, including the parts that aren't flattering.
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
BuzzWire's answer:
Official Instagram Graph API (Verified Meta Tech Provider — not endorsed by or affiliated with Meta/Instagram) Next.js with static export, served on Vercel's CDN Tailwind CSS
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
BuzzWire's answer:
Solo creators with 10K–150K followers who monetize through their link-in-bio — lead magnets, digital products, affiliate links, bookings. Strongest fit: fitness and digital-product creators. The moment BuzzWire is built for: a post takes off, hundreds of people comment the keyword, and every one of them gets answered in seconds — at peak intent — with email capture happening inside the conversation.
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.
BuzzWire's answer:
Two reasons. Pricing: most DM tools meter the thing creators can't predict — ManyChat's free tier is now 25 contacts/month with per-contact overage billing, and metered plans fail at the exact moment a post goes viral. BuzzWire has no contact caps on any plan; Pro is a flat $9.99/mo. Safety: competitors answer the ban question with a blog post; BuzzWire answers it with enforced mechanisms you can verify against Meta's own published limits. We won't promise you'll never get banned — nobody honestly can — but we can show you exactly what the tool does and why.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
BuzzWire's answer:
Leave this one blank. BuzzWire is pre-launch with no nameable customers, and the truth-in-marketing rule bars filling it with anything invented. An empty field on a directory reads as "new product"; a fabricated one is a credibility debt. Revisit after the first creators agree to be named.
BuzzWire's answer:
Safety is the architecture, not a marketing claim. BuzzWire connects through the official Instagram Graph API (never your password) and enforces Meta's actual published limits as product properties: 200 DMs/hour — Meta's own ceiling — a 4-week warm-up ramp for new accounts, one DM per person per 24 hours, message variation on every send, and auto-pause on Meta policy signals. The safety caps are identical on Free and Pro: you cannot pay to send faster. And the Free plan is free forever — unlimited automations, no contact caps.

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
