Analysis of StackPicks.dev

Overall verdict

  • StackPicks.dev appears to be a niche tool aimed at helping developers choose technology stacks, but without verified independent reviews or extensive user data, its overall quality is hard to confirm definitivelyโ€”it may be useful as a quick-reference resource but shouldn't be your only source for stack decisions.

Why this product is good

  • Focuses specifically on tech stack recommendations, which can save time during initial research
  • Likely curated or aggregated by developers familiar with common stack combinations
  • Simple, targeted tool rather than a bloated all-in-one platform
  • Could provide quick comparisons for popular frameworks, languages, and tools

Recommended for

  • Developers exploring new technology stacks for side projects
  • Beginners wanting a starting point before diving into deeper research
  • Small teams brainstorming initial architecture options
  • Anyone wanting a quick reference rather than an exhaustive technical guide

Questions & Answers

As answered by people managing Duolingo and StackPicks.dev.

Who are some of the biggest customers of your product?

StackPicks.dev's answer:

Indie developers and AI builders Solo founders and small startup teams Affiliate marketers connecting ad platforms to Claude (For that last one โ€” if a field requires real company names, just leave it empty. Never invent customers; SaaSHub and AI crawlers penalize fabricated claims, and it can bite you later. "Early-stage, used by indie builders" is the honest + safe answer.)

What makes your product unique?

StackPicks.dev's answer:

StackPicks combines two things nobody else bundles: a curated directory of 165+ open-source dev tools with honest "use this / skip this" takes, AND a unified MCP gateway that connects 800+ apps to AI agents through one OAuth link. Most directories just list star counts; most MCP tools are developer-only and bill per call. StackPicks gives you both โ€” opinionated curation plus consumer-grade Claude integration โ€” for a one-time $2.99 lifetime fee, no subscription.

Why should a person choose your product over its competitors?

StackPicks.dev's answer:

Composio and Pipedream are powerful but built for developers and priced per usage. StackPicks Connect is consumer-grade: paste one URL into Claude, log in through your browser, and every connected app works โ€” no API keys, no per-call billing. It's bundled into a one-time lifetime plan instead of a meter. For solo builders, indie hackers, and small teams who just want their AI agent to use their apps, it's the simplest and cheapest path.

How would you describe the primary audience of your product?

StackPicks.dev's answer:

Solo developers, indie hackers, AI builders, and small startup teams โ€” people who use Claude, Cursor, or ChatGPT daily and want their AI agent to actually do things across GitHub, Gmail, Slack, Notion, and their ad platforms. Also marketers and growth folks who want to pull ad-platform data (Meta Ads, Google Ads) into Claude. India-first pricing via Razorpay, but used globally.

What's the story behind your product?

StackPicks.dev's answer:

StackPicks started as a curated directory of open-source dev tools โ€” the differentiator being honest curator takes instead of raw GitHub star counts. As MCP (Model Context Protocol) took off in 2025-26, it became clear that connecting apps to AI agents was painful: one MCP server per app, a wall of config, API keys everywhere. So we built StackPicks Connect โ€” a unified gateway that connects 800+ apps to Claude and Cursor through a single OAuth link. Built solo by Piyush Jangir.

Which are the primary technologies used for building your product?

StackPicks.dev's answer:

Next.js 15 (App Router), TypeScript, Supabase (Postgres + Auth), Razorpay for payments, Nango for OAuth, and the Model Context Protocol (MCP) for the AI-agent gateway. Hosted on Railway.

Duolingo Reviews

  1. A review

    It's incredibly easy to use and the regular reminder from the app about practicing more keep you consistent. Besides,in my opinion,it also can be not only a tool for learning languages,but a good entertainment for kids too. I've been practicing here almost every day throughout the year and i highly recommend Duolingo:))

    ๐Ÿ‘ Pros:    I added everything i want to be mentioned above
    ๐Ÿ‘Ž Cons:    Perhaps the design may look "too childish" for some adults,but it's only the matter of taste
  2. Pretty good

    Duolingo is a quite nice language learning app for the begginers and for those who want to know a certain language on a pretty good medium level(It's like something between A2-B1,i suppose). Moreover, I'd like to admit it's can be useful for kids as well because the app has cute design and playable interactions , challenges and its own little app - shop where you can buy different bonuses for you ,and in my opinion,children could like an idea of learning languages in a playable form. Though, Duolingo can be rather annoying, when you miss one or two days of studying ,so it'd be really awesome if my brother,for example, who uses this app ,could make his own studying schedule here.

  • how gamifying my life helped me build better habits and achieve my goals
    Duolingo: a language-learning app that uses points, levels, and rewards to keep you motivated. This is the most effective when you do it with your friends or a group of people who share your learning goals. I got really addicted to checking my leaderboard rankings everyday.

  • Brushing up on Spanish
    Hi! I wish I'd seen a post like this a few months ago. I would have been interested then. By now it's a little late for me. I just signed up for the 2 week free trial since that's about all the time I have left before I leave. If you can, use a desktop computer/laptop to do duolingo.com and it will have no ads and unlimited hearts! Not as convenient as the app on a phone but saves tons of time and you can do it...
