STACK GUIDE

The Best AI Stack for Indie Hackers in 2026 (Under $100/mo)

May 2026 · 8 min read · By Hektiq

The average indie hacker we audit is spending $191/mo on AI and SaaS tools. The most efficient ones — the ones actually profitable — are running lean stacks under $100/mo with zero overlap. Here's exactly what they're using and why.

This isn't a sponsored list. These are the tools that consistently show up in high-health, low-waste stacks across hundreds of builder audits.

The Lean Builder Stack (Under $100/mo)

Five tools. That's it. Everything else is either overlap or dead weight.

AI CORE
Claude API (Anthropic)
Best-in-class for long context, reasoning, and writing. Powers your product AND replaces the need for a separate AI chat subscription via claude.ai. Pay-as-you-go means you only pay for what you use.
~$15–30/mo
AI CODE
Cursor Pro
The only AI coding tool worth paying for in 2026. Composer (multi-file edits), full codebase context, and model choice make it the clear winner. Replaces GitHub Copilot entirely.
$20/mo
HOSTING
Vercel Pro
Best developer experience for deploying React/Next.js apps. Serverless functions, edge network, and preview deployments. The free tier covers most early-stage products.
$0–20/mo
DATABASE + AUTH
Supabase
Postgres database, auth, storage, and realtime — all in one. The free tier is genuinely generous. Replaces Firebase, PlanetScale, and a separate auth provider. One subscription instead of three.
$0–25/mo
ANALYTICS
PostHog
Product analytics, session replay, feature flags, and A/B testing on one platform. Free up to 1M events/mo. Replaces Mixpanel, Amplitude, and hotjar at once.
$0/mo
TOTAL MONTHLY STACK COST
Early stage, moderate usage
~$35–95/mo

What Efficient Builders Cut First

When we audit stacks that are over $150/mo, these are the tools that almost always get flagged and removed:

GitHub Copilot
Fully overlaps with Cursor. Zero reason to run both.
−$10/mo
ChatGPT Plus
Overlaps with Claude API. Claude.ai free tier covers daily chat.
−$20/mo
Perplexity Pro
Web search via Claude or ChatGPT covers 90% of the use case.
−$20/mo
Notion AI
If you already have Claude API, Notion AI adds nothing unique.
−$10/mo
Midjourney
If you're not shipping visual-heavy work weekly, this is idle spend.
−$10–48/mo

The Rule Most Efficient Builders Follow

"No tool stays in the stack unless it's used at least 3 times a week or directly attributable to revenue." — common pattern among profitable indie hackers

This single rule eliminates most stack bloat. The tools you pay for but rarely touch — Midjourney, a second AI assistant, a design tool you opened twice — those are what separate a $200/mo stack from a $70/mo one.

How to Audit Your Own Stack

The fastest way to find your waste is to map every AI and SaaS subscription against these two questions: "Did I use this in the last 14 days?" and "Does another tool in my stack do the same thing?" If the answer to either is no/yes respectively, you have a cut candidate.

Hektiq does this automatically — it detects overlap pairs, flags inactive tools, and shows your stack health score with specific recommendations for what to cut or replace.
