MemRadar VS Cert Decoder

MemRadar's answer

I was shopping for a memory upgrade during the 2025-26 price surge and could not tell whether the kit in front of me was a bad price or just a bad market. Discount badges are calculated off inflated baselines, so they tell you nothing. I wanted real history for the specific product, and nothing focused on memory and storage existed, so I built it. It has grown into a two-retailer comparison with a market-wide price index, but the original question is still the one every page tries to answer.

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.

MemRadar's answer

Static HTML generated per product, so every product has a real indexable page rather than client-side routing. Supabase for price history storage, Chart.js for the charts, GitHub Actions for scheduled price fetches, and Cloudflare in front. Price data is licensed from Keepa for Amazon history and comes via Rakuten Advertising's product feed for Newegg. Deliberately boring and fast.

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

MemRadar's answer

PC builders and upgraders who already know roughly what they want and are trying to time the purchase. They tend to be technical, skeptical of discount badges, and comfortable reading a chart. The most common question MemRadar answers is some version of "is this a fair price right now, or should I wait?"

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

MemRadar's answer

General price trackers cover millions of products and treat memory as one category among thousands. MemRadar covers 235 RAM and SSD products and nothing else, so the comparisons are specific: price per GB against the median for that product's segment, a capacity switcher to compare the 1TB against the 4TB of the same drive, and a market index showing how DDR5, DDR4, NVMe, and SATA are each moving. Prices come from licensed sources rather than scraping, and update every few hours. Free, no account, no ads.

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.

MemRadar's answer

Depth of history in a narrow niche. MemRadar tracks only RAM and SSDs, but tracks them properly: some kits have price data going back to 2015, so you can see what a product cost before the memory price surge, not just what it cost last month. Every product page turns that history into a plain-English read on whether the current price is genuinely good or only good lately, which is a distinction that matters enormously in the current market.
