Questions & Answers

As answered by people managing Simplenote and APIMaster.

Which are the primary technologies used for building your product?

APIMaster's answer:

Next.js, Go, Python (Flask), PostgreSQL

What makes your product unique?

APIMaster's answer:

Fingerprint verification โ€” we test every provider weekly using behavioral fingerprinting to detect model substitution. You can see which providers serve real models vs fake substitutes on our public leaderboard. No other API marketplace does this.

Why should a person choose your product over its competitors?

APIMaster's answer:

APIMaster is the only marketplace that verifies what model you're actually getting. Competitors like OpenRouter route traffic without verification โ€” you might pay for Claude Opus but receive a cheaper model. APIMaster detects this and only recommends verified providers. Plus, prices are up to 90% off official rates โ€” you get both cost savings and model authenticity guaranteed.

How would you describe the primary audience of your product?

APIMaster's answer:

Developers who use OpenAI, Claude, or DeepSeek APIs and want to reduce costs without sacrificing model quality. Especially useful for developers in markets where direct API access is expensive or restricted.

What's the story behind your product?

APIMaster's answer:

Built after discovering that many cheap API resellers secretly substitute expensive models with cheaper ones. We built fingerprint detection first, then a marketplace that only lists providers that pass verification.

Simplenote Reviews

  1. Basic

    I've started with Simplenote years ago, at the time I was happy but it became clear pretty quickly that it was too basic. But to be fair, it's basic and free. Keep in mind it's unencrypted.

    ๐Ÿ Competitors: PrivacyNotes, Standard Notes, Joplin
  2. Exceptional for what its doing

    Was looking for an alternative for OneNote, so I found it here. I like how simple the interface is and the UI is very simple. It's good for what it is, but there is no sorting/topic system which makes it difficult to find specific notes for specific topics. Other than that, it's a good note system.

    ๐Ÿ Competitors: OneNote, Evernote
    ๐Ÿ‘ Pros:    Lots of functionalities|Easy user interface|Easy to use|Simple
    ๐Ÿ‘Ž Cons:    No groups for notes|No sorting notes

    I've been looking to migrate away from https://simplenote.com to something else and I've been dragging my feet. However, what's happened in the past 2 weeks with the CEO was the push I needed to resume looking for another solution. I've landed on Obsidian.md. I actually prefer Simplenote over Obisidian, because Simplenote feels smoother and the online web app is great, but I've decided that having more control... - Source: Hacker News / almost 2 years ago
  • Ask HN: What note taking app do you use and why?

  • Anybody have problems with bookmark organization like me?
    Bookmarks serve two purposes: - Quick access to commonly used links. For this, I built https://multi-launch.leftium.com - Saving a link for future reference. Often I want to also save plain text notes for future reference, so find myself using https://simplenote.com I have also used https://www.bkmks.com to save links. I'm working on an app that will help save and organize everything: bookmarks, notes, and tasks. - Source: Hacker News / about 2 years ago
  • Ask HN: Looking for a simple note taking tool
    It doesn't meet the poster's needs, but Simplenote is still a thing for people who want text-only notes, Markdown, and easy access to plain text files. It got acquired by Automattic a few years back. https://simplenote.com/. - Source: Hacker News / about 2 years ago

    Https://noteplan.co is a very similar app. Unfortunately I couldn't use it because it was limited to iOS devices (a web version is in development). - One thing missing in craftnote is search. That is a must-have feature for me. - I also like being able to publicly share notes with a (short) URL. See https://simplenote.com for an example of how this is done.
