Overall verdict

  • I don't have verified information about GalleryPlanner (gallery-planner.com) in my training data, so I can't confirm its features, pricing, reliability, or user satisfaction with confidence. I'd recommend checking recent reviews, trying any free trial, and verifying company legitimacy before committing.

Why this product is good

  • No firsthand or verified data available on this specific tool's features or performance
  • Unable to confirm user reviews, ratings, or reputation from reliable sources

Recommended for

  • Users who have independently verified the site's legitimacy and reviews
  • Those willing to test with a free trial or demo before paying
  • Buyers who check recent third-party reviews (e.g., Trustpilot, G2) first
  • People comfortable reaching out directly to the company with questions before purchasing

Overall verdict

  • Cert Decoder appears to be a free online tool for decoding and inspecting SSL/TLS certificates, CSRs, and related cryptographic data, making it useful for quick, no-install certificate analysis, though it should be used with awareness of general web tool privacy considerations when handling sensitive certificate data.

Why this product is good

  • Provides quick, browser-based decoding of certificates without needing to install software
  • Useful for troubleshooting SSL/TLS certificate issues on the fly
  • Simple interface aimed at both technical and semi-technical users

Questions & Answers

As answered by people managing GalleryPlanner and Cert Decoder.

What's the story behind your product?

GalleryPlanner's answer

GalleryPlanner was created by Tim Straub, a data scientist, after a real home project: turning a growing family frame collection into a clean wall layout with exact spacing.

Existing options did not meet two core needs:

  • precision (exact nail placement and spacing),
  • privacy (no unnecessary cloud photo uploads).

So he built GalleryPlanner as a local-first, measurement-accurate planner for practical, confidence-first installs.

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.

Which are the primary technologies used for building your product?

GalleryPlanner's answer

Core stack

  • React 19 + TypeScript + Vite
  • CSS Modules UI architecture
  • IndexedDB/browser storage for local-first persistence

Feature stack

  • TensorFlow.js tooling for on-device photo analysis
  • Clerk for account/auth flows
  • Lemon Squeezy for Pro purchase and entitlement workflows

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

How would you describe the primary audience of your product?

GalleryPlanner's answer

Primary audience: people planning real gallery walls in real homes.

  • Homeowners and renters
  • Families using personal photos
  • Design-focused DIY users
  • Independent interior designers/decorators

It is especially useful for anyone who wants a measurable plan, not just visual inspiration.

Cert Decoder's answer:

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

Why should a person choose your product over its competitors?

GalleryPlanner's answer

Choose GalleryPlanner if accuracy and execution matter.

  • More practical than generic mockup tools: built for real frame inventory and real wall measurements.
  • Privacy-first workflow: no forced cloud upload of family photos.
  • Faster design decisions: AI-assisted layout and photo placement.
  • Clear value model: free core planning, plus one-time Pro for advanced AI/export workflows.

Compared with tools like ArtPlacer and other broad visual planners, GalleryPlanner is optimized for people who want to actually hang the wall confidently.

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.

Who are some of the biggest customers of your product?

GalleryPlanner's answer

  • DIY homeowners
  • families planning personal gallery walls
  • independent interior designers using client previews

Cert Decoder's answer:

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

What makes your product unique?

GalleryPlanner's answer

GalleryPlanner blends precision + privacy + AI in one tool.

  • True-to-scale planning: design with exact wall and frame dimensions.
  • Local-first by default: your personal photos stay on-device.
  • AI where it helps most: Smart Layout + Smart Fill accelerate decisions.
  • Execution-ready exports: Pro includes install-focused outputs like printable PDF hanging guides.

Bottom line: it is not just a mood-board app, it is a practical planning workflow from idea to install.

    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
