PropelAuth
StackPicks.devStackPicks.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.)
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.
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.
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.
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.
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.
