FREE RESOURCE · FROM THE "STACK" REEL

The AI startup stack: 14 tools, their real prices and the honest monthly bill (checked Oct 2026)

By Hammad Yousuf · 18 October 2026

The short answer: about $21 a month while you build a personal prototype, and about $41 a month once you charge customers, plus card fees.

The honest monthly bill

The honest monthly bill for the AI startup stack, by stage
Stage	What you pay for	Monthly
Personal prototype (not charging anyone)	Claude Pro $20 + a .com at $11.48 for year one (about $0.96 a month). Everything else on free tiers	about $21
Same, Claude billed yearly	Claude Pro $200 up front (Anthropic lists it as $17 a month) + the domain	about $18
Running it as a business (taking payments)	+ Vercel Pro $20, because the free Hobby plan is non-commercial only	about $41 + card fees
Business, year two	The .com renews at $18.48 + $0.20 ICANN fee ($18.68, about $1.56 a month)	about $42 + card fees

Card fees: Stripe charges 2.9% + 30¢ per successful US card payment, with no monthly fee. On a $20 payment that is $0.88 (4.4%), so the fixed 30¢ matters on small prices. In the UAE, Stripe's own page shows 2.9% + AED 1.00 per domestic card payment.

Not in these totals:

n8n, unless you self-host it on a machine you already pay for. n8n Cloud Starter was $20 a month billed annually on 18 Oct 2026 (as shown to a UAE visitor).
Claude Max (from $100 a month), if Pro's usage limits are too tight for how much you code with it.
Upgrades once a free tier runs out (see "When you start paying").
Any tax your country adds at checkout.

If every free tier ran out at once, the next plans would add about $116 a month on top of the $41: Supabase Pro $25, Clerk Pro $25, Resend Pro $20, Sentry Team $26 (billed annually) and n8n Cloud Starter $20 (billed annually), plus usage-based Upstash and Qdrant. Most products hit one or two limits long before all of them.

Layer 1: AI coding

1. Claude Pro, with Claude Code

What it does: Claude Code is the coding agent that writes, edits and runs your app's code from your terminal or desktop.
Price: $20 a month billed monthly, or $17 a month with the annual discount ($200 billed up front).
Free plan: Claude Code is not included in the Free plan; it starts on Pro.
When you outgrow it: Max starts at $100 a month for people who work with Claude all day.

Layer 2: data

2. Supabase

What it does: a Postgres database with auth, file storage, edge functions and the pgvector extension for vector search.
Free plan ($0): 2 active projects, 500 MB database, 50,000 monthly active users, 1 GB file storage, 5 GB egress.
Catch: free projects are paused after 1 week of inactivity.
Next plan: Pro, from $25 a month.

8. Upstash Redis

What it does: a hosted Redis for caching and rate limiting.
Free plan ($0): 250 MB of data, 500K commands a month, 10 GB bandwidth a month.
Next plan: pay as you go at $0.20 per 100K commands.

Source: upstash.com/pricing/redis (checked 18 Oct 2026). Start here: upstash.com/docs/redis/overall/getstarted

9. Qdrant Cloud, or pgvector in Supabase

What it does: a vector database that stores embeddings, so your app can search by meaning (AI search, RAG).
Free tier (free forever): a single-node cluster with 0.5 vCPU, 1 GB RAM and 4 GB disk, which Qdrant sizes at about 1M 768-dimension vectors.
Catch: a free cluster is suspended after 1 week unused and deleted after 4 weeks unused.
Open source: the Qdrant engine is Apache-2.0 licensed.
Skip it if you can: pgvector runs inside your Supabase database at no extra cost, which is one less tool.

Layer 3: ship it

6. GitHub

What it does: hosts your code and its history (version control), and runs automations with GitHub Actions.
Free plan ($0, forever): unlimited public and private repositories, 2,000 Actions minutes a month, 500 MB of Packages storage, and 120 Codespaces core-hours for personal accounts. Private repositories get a smaller feature set than paid plans.

3. Vercel

What it does: builds and deploys your app every time you push to GitHub.
Hobby ($0): for non-commercial, personal use only. Vercel's fair use guidelines (updated 14 Sep 2026) count any deployment that makes money for anyone involved as commercial, including asking for or processing payments.
Pro ($20 a month): includes $20 of usage credit. This is the plan a startup that charges customers needs.
Alternative: if your site is static, Cloudflare does not charge for requests to static assets on its free or paid plans (developers.cloudflare.com/pages/functions/pricing).

Sources: vercel.com/pricing, vercel.com/docs/plans/hobby and vercel.com/docs/limits/fair-use-guidelines (checked 18 Oct 2026)

4. Domain: Namecheap (or Cloudflare Registrar)

What it does: your .com.
Namecheap .com: $11.28 for the first year (25% off $14.98), plus ICANN's $0.20 annual fee, which applies to every registration, renewal and transfer. That is $11.48, or about $0.96 a month. New customers can get the first year for $6.48 with the promo code shown on the page.
Renewal: $18.48 a year from year two, plus the $0.20 fee (about $1.56 a month).
Price rise: Verisign raises the .com wholesale price from $10.26 to $10.97 on 1 Nov 2026 (reported by Domain Incite, 27 Apr 2026), and Namecheap's own banner warns that .com registry prices are rising. Re-check the price if you buy after 1 Nov.
Alternative: Cloudflare Registrar says it does not mark up domain prices; you pay what the registry and ICANN charge (www.cloudflare.com/domains).

Sources: www.namecheap.com/domains/registration/gtld/com (checked 18 Oct 2026) and domainincite.com/31668-more-verisign-bitchiness-as-com-prices-rise-revealed

10. Cloudflare DNS

What it does: authoritative DNS, which points your domain at Vercel, your email provider and the rest.
Price: available on all Cloudflare plans, including the free one.

Sources: developers.cloudflare.com/dns (checked 18 Oct 2026) and www.cloudflare.com/plans

Layer 4: users and money

11. Clerk

What it does: sign-up, sign-in and user profiles, with prebuilt UI.
Hobby (free, no card): 50,000 monthly retained users per app. A user counts as retained when they come back 24 hours or more after signing up.
Catch: the free plan shows Clerk branding and has no multi-factor authentication (MFA).
Next plan: Pro at $25 a month, or $20 a month billed annually.
Skip it if you can: Supabase includes auth, so you may not need both.

Source: clerk.com/pricing (checked 18 Oct 2026). Docs: clerk.com/docs

12. Resend

What it does: sends your app's transactional email: welcome emails, receipts, password resets.
Free plan ($0): 3,000 emails a month, 100 emails a day, 3 domains.
Next plan: Pro at $20 a month for 50,000 emails, with no daily limit.

Source: resend.com/pricing (checked 18 Oct 2026). Docs: resend.com/docs/introduction

5. Stripe

What it does: takes card payments and runs checkout.
US: 2.9% + 30¢ per successful domestic card payment, +1.5% for international cards, +1% when currency conversion is needed. No setup or monthly fee.
UAE: 2.9% + AED 1.00 per successful domestic card payment, +1% for international cards, +1% for currency conversion.
Honest note: stripe.com sends visitors to their local pricing page. From the UAE it showed the AED rates above on 18 Oct 2026; the US rate comes from two 2026 fee guides (dodopayments.com/blogs/stripe-fees-calculator and merchantinsiders.com/blogs/stripe-fees). Check stripe.com/pricing from your own country.

Docs: docs.stripe.com/payments/checkout (build it in test mode first)

Layer 5: learn and fix

7. PostHog

What it does: product analytics (what users do), session replay, feature flags, surveys and error tracking.
Free every month, card or no card: 1M analytics events, 5K session recordings, 1M feature-flag requests, 100K error-tracking exceptions, 1,500 survey responses. The free plan covers 1 project with 1-year data retention.
PostHog says 97% of companies use it for free.

13. Sentry

What it does: tells you when your app throws an error or slows down, with the stack trace.
Developer (free): limited to 1 user; 5k errors, 5M tracing spans and 50 session replays.
Next plan: Team at $26 a month billed annually, with unlimited users.

Source: sentry.io/pricing (checked 18 Oct 2026). Docs: docs.sentry.io

Layer 6: automate

14. n8n

What it does: visual workflows that connect your stack (new sign-up alerts, onboarding emails, reports).
Self-hosted Community Edition: free. Without a licence key, a self-hosted install runs as the free Community edition.
Licence: the Sustainable Use License. It is "fair-code", not an OSI open-source licence, and allows use for your own internal business purposes.
Catch: self-hosting needs a server, and that server is not free.
n8n Cloud: Starter was $20 a month billed annually for 2.5K workflow executions on 18 Oct 2026 (as shown to a UAE visitor).

Set it up in this order

GitHub: create a private repository.
Claude Code: on Claude Pro, ask it to scaffold the app in that repository (prompt 2 below).
Supabase: create a project for the database and auth; switch on pgvector only if you need AI search.
Vercel: import the GitHub repository. Hobby is fine while it is a personal prototype; move to Pro before you charge anyone.
Domain + DNS: buy the .com, manage its DNS on Cloudflare, and connect it to Vercel.
Login: add Clerk, or use Supabase Auth and skip Clerk.
Email: add Resend for welcome and password-reset emails.
Payments: build Stripe Checkout in test mode; switch to live keys only after a test payment works end to end.
PostHog + Sentry: add both before your first real users, so you see what they do and what breaks.
Upstash and Qdrant (or pgvector): only when you need caching, rate limits or vector search.
n8n: automate the repetitive work last, once you know which work repeats.

Free-tier gotchas

Supabase pauses free projects after 1 week of inactivity, and the free plan allows 2 active projects.
Qdrant suspends a free cluster after 1 week unused and deletes it after 4 weeks.
Vercel Hobby is for non-commercial personal use only.
Clerk Hobby shows Clerk branding and has no MFA.
Resend's free plan stops at 100 emails a day.
Sentry's free plan is limited to 1 user.
PostHog's free plan covers 1 project with 1-year retention.
A domain renews at a higher price than its first year.
n8n is free only when you self-host it; n8n Cloud is paid.

When you start paying

When to upgrade each tool, and the next plan's price
Tool	Upgrade when	Next price
Vercel	you charge customers	Pro $20/month (includes $20 usage credit)
Supabase	you pass 500 MB, 50,000 MAU or 2 projects, or can't accept idle pauses	Pro from $25/month
Clerk	you pass 50,000 retained users per app, or need MFA or no branding	Pro $25/month ($20 billed annually)
Resend	you send over 100 emails a day or 3,000 a month	Pro $20/month for 50,000 emails
Sentry	a second person needs access, or you pass 5k errors	Team $26/month billed annually
n8n	you want n8n to host it for you	Cloud Starter $20/month billed annually
Upstash	you pass 500K commands a month	$0.20 per 100K commands
Claude	Pro's usage limits slow you down	Max from $100/month

Four numbers people get wrong

"Under $20 a month." Not possible with this stack: Claude Pro alone is $20, and a domain is extra, so about $21 is the floor.
"Vercel is free." Only for personal, non-commercial projects. Charging customers means Pro at $20 a month.
"A domain is $1 a month." Domains bill yearly: $11.48 for a Namecheap .com in year one, then $18.68 a year.
"Stripe takes 2.9%." In the US it is 2.9% + 30¢ per card payment, so a $20 sale costs $0.88, not $0.58.

Why one person can build this now

Carta: the share of new US startups (companies on Carta) with a solo founder rose from 23.7% in 2019 to 36.3% in H1 2025, which is +12.6 points. Carta reads it as the barriers to launching a startup falling; the data itself does not say what caused it. Source: Carta Solo Founders Report, 9 Dec 2025, carta.com/data/solo-founders-report
Nasdaq Economic Institute (9 Jun 2026): new US business applications have climbed sharply since early 2025, almost entirely from one-person businesses, while applications from firms likely to hire have stayed flat.

Copy-paste prompts

Pick my stack (Claude or ChatGPT)

prompt 1 of 4

You are helping a solo founder choose a lean AI startup stack.
My product: [one sentence].
Who pays and how: [for example, a $20/month subscription from US customers].
Users I expect in the first 6 months: [number].

Start from this 14-tool stack: Claude Pro with Claude Code, Supabase, Vercel, a .com from Namecheap or Cloudflare Registrar, Cloudflare DNS, Stripe, GitHub, PostHog, Upstash Redis, Qdrant Cloud or pgvector in Supabase, Clerk, Resend, Sentry, n8n.

1. Tell me which layers I need for the first version and which I can skip (for example Supabase Auth instead of Clerk, or pgvector instead of Qdrant).
2. For every tool I keep: the plan I need once I charge customers, its monthly price, the free-tier limit I am most likely to hit first, and a link to the official pricing page.
3. Flag any free plan that does not allow commercial use.
4. Total the monthly cost for (a) a personal prototype and (b) the first month I take payments, with card fees as a separate line.
Do not guess prices. If you cannot check a price on the official page, say so.

Plan the build (Claude Code)

prompt 2 of 4

Read this repo, then write BUILD_PLAN.md for shipping the first version on GitHub + Supabase + Vercel + Stripe (test mode) + PostHog + Sentry + Resend. For each service give: the setup step, the environment variable NAMES it needs (never values), where each one goes (.env.local and the Vercel project settings), and a one-line check that proves the integration works. Order the steps so the app is deployed by step 3 and takes a Stripe test payment by the last step. Do not create accounts, switch on paid plans or paste any keys: stop and tell me when a step needs me.

Which free tier runs out first

prompt 3 of 4

Here is my usage for the last 30 days: monthly active users [ ], database size [ ], file storage [ ], peak emails per day [ ], emails per month [ ], analytics events [ ], errors [ ], Redis commands [ ]. My usage grows about [ ]% a month.
Compare each number with these free-tier limits (checked 18 Oct 2026): Supabase 50,000 MAU, 500 MB database, 1 GB file storage; Resend 3,000 emails a month and 100 a day; PostHog 1M events a month; Sentry 5k errors; Upstash Redis 500K commands a month and 250 MB.
Tell me which limit I hit first, roughly when, and what the next plan costs. Re-check every limit on the official pricing page before you answer, because prices change.

Commercial-use check before launch

prompt 4 of 4

List every third-party service this repo uses (package.json, .env.example, config files). For each one, tell me which plan I seem to be on and whether that plan allows commercial use, with a link to the provider's pricing page or terms. Mark anything you could not confirm as CHECK MANUALLY. Vercel's Hobby plan, for example, is for non-commercial personal use only.

Honest caveats

Prices and free tiers change often. Everything here was checked on 18 Oct 2026; check the pricing page again on the day you sign up.
The totals assume one person on each plan and usage inside the free tiers. Heavy AI coding can push you from Claude Pro to Max.
The Stripe US rate is from secondary 2026 fee guides, because stripe.com shows local pricing by location.
The n8n Cloud price is the one shown to a UAE visitor; your currency may differ.
Free tiers are for getting started. Read the limits for anything your business depends on (pauses, suspensions, daily caps, one-user plans).
This is a cost guide, not financial or legal advice.
