1Tools & MCPs — give your AI hands
Plugs that let your agent build, store data, ship, and see the web. Start with the first four.
Playwright MCP
☆Drives a real browser — click, type, screenshot.
freeQAstart-here
Microsoft-official. Lets the AI actually operate a browser to test your sites and scrape JS pages. Token-cheap (no vision model needed). Why you: gives the AI eyes+hands on the web to QA your own builds.
Supabase MCP
☆Instant database + logins + storage.
freestart-here
Agent provisions your DB, auth and storage by talking to Supabase directly. Why you: almost every idea below needs 'users + a database' — this kills the most annoying setup step. Generous free tier.
GitHub MCP
☆Spin up repos & push in one sentence.
freestart-here
Creates repos, opens PRs, manages issues. Why you: you already ship to github.com/geoakser-afk — makes it one command instead of manual git.
Vercel MCP
☆Ship it live with a command.
freestart-here
Deploy, read build logs, manage deployments. Why you: free tier hosts small apps at zero cost — perfect for your volume strategy.
Firecrawl MCP
☆Turn any website into clean data.
free tierscraping
Crawl whole sites, structured extraction, change monitoring. Why you: the muscle behind lead lists, competitor data, any 'pull data from the web' feature — your Vault wheelhouse.
Stripe MCP
☆The money layer — take payments.
free*payments
Creates products, payment links, checkout. Why you: the day an idea needs 'let people pay,' this wires it in minutes. Free — Stripe only takes its normal cut when you actually charge.
Exa / web search MCP
☆Let the AI research live.
free tier
AI-native web search + page fetch. Why you: find prospects, check 'does this exist,' pull current facts instead of guessing from old training data. Works anonymously, rate-limited.
Replicate MCP
☆The 'Bartr trick' — photo → AI image.
cents/img
Run any model on demand, incl. image generation. Why you: snap a photo → clean listing art / thumbnails. Pay-per-use, cents per image. Or run it free on your RX 9060 XT.
Context7 MCP
☆Feeds the AI current library docs.
freequality
Injects version-specific docs so the AI stops writing outdated code. A quiet quality boost on every fast build.
2Templates — start 80% done
Don't start from a blank page. Bend one of these to the idea.
Lovable
☆Describe an app → it ships full-stack.
fastestlive-today
Chat-to-app: auth + database + backend + hosting, all wired. Best fit: your 'week-one Bartr speed' move — fastest 0-to-live for teen/creator apps.
v0 (Vercel)
☆Cleanest code to hand to Claude.
free tier
Generates clean Next.js + Tailwind + shadcn/ui, one-click deploy. Best fit: when you want the nicest code for me to then extend — best code quality of the builders.
create-next-app + Supabase
☆The $0 default backbone.
freeown-the-code
Next.js pre-wired with Supabase auth, Postgres, storage. Best fit: the default foundation for most of your apps — social, community, creator tools — for $0. (This armory app is built on exactly this.)

free 50k

Sharetribe
☆Marketplace-in-a-box (Bartr-style).
trial→paid
Profiles, listings, Stripe payments, admin, all done. Best fit: teen/creator marketplaces — fastest legit path; you don't rebuild payments/escrow.
LinkStack
☆Free open-source Linktree.
free
Self-hostable link-in-bio: multi-user, themes, analytics. Best fit: a creator link-in-bio product, ready today for $0.
3Opportunity menu — what to build
Skim, react, star. Teen/creator apps first, then a finance lane for you + Koa.
⚖️ Finance ground rule: building tools + educational content = wide open. Regulated = personalized advice on specific securities for pay, or holding others' money. No solo brokerage under 18 (paper trading needs no account). Route any money through a parent/parent-LLC. 📡 Data: use free Alpaca (stocks+paper) + CoinGecko (crypto). Skip Alpha Vantage (gutted to 25/day). Backtest with backtesting.py.
EASY★ PICK☆
AI listing-cleaner for resellers
The 'Bartr trick' as its own tool: messy photo → clean image + written listing.
Who: teen resellers on Depop/eBay/FB Marketplace who hate writing listings. Money: freemium — free for a few/month, subscribe for unlimited. Build: Easy–Medium — mostly image-gen + an LLM prompt over an upload form. Your friend's best feature, repackaged as yours.
EASY☆
Group-decision app
Friends drop options, everyone swipes, the app picks. 'Where do we eat/what do we watch.'
Who: teen friend groups — your exact world. Money: free + affiliate links (restaurants, tickets) or a cheap 'pro group' tier. Build: Easy — realtime voting is a solved Supabase pattern; you win on taste and polish.
EASY☆
Study-set generator
Paste notes / photo a textbook → flashcards, quiz, summary. Shareable library.
Who: high schoolers (your exact market). Money: freemium; shared sets behind a small sub. Build: Easy–Medium — LLM does the work; moat is clean UI + a growing shared library.
EASY☆
Teen-creator link-in-bio
Sharper Linktree with AI bios + built-in tip/book/buy.
Who: small creators, athletes, artists at your school and beyond. Money: free tier + paid themes/domain; take a cut of tips/sales. Build: Easy — templates exist; you win on teen-native design taste.
MEDIUM★ PICK☆
Tournament / bracket app
Run brackets for 2K, Smash, wrestling, pickup tourneys — live standings + share links.
Who: your BJJ/wrestling/gaming circles first — you're your own launch audience. Money: free to run, charge for 'pro' events (branding, entry-fee collection with a cut). Build: Medium — bracket logic + realtime; genuinely sticky.
EASY☆
Anonymous hype / feedback board
Safe, AI-moderated space to send anonymous compliments to a team or class.
Who: sports teams, clubs, grades. Money: free virally, then paid 'verified org' boards. Build: Easy–Medium — the AI moderation layer is the whole product; keep it clean and it spreads itself.
MEDIUM☆
AI thumbnail + clip helper
Upload a video → thumbnail concepts, hook titles, auto-cut clip timestamps.
Who: teen YouTubers/TikTokers grinding content. Money: credits/subscription — creators pay for anything that saves editing time. Build: Medium — even the thumbnail+title half ships as its own product.
MEDIUM☆
Hyper-local teen-services board
Teens list services (tutoring, lawns, tech help), neighbors book them.
Who: teens wanting income + neighbors wanting help. Bartr's energy, for services + money. Money: booking fee or featured listings — you take a cut. Build: Medium — two-sided; use Sharetribe to skip the hard parts.
EASY★ PICK☆
Discipline tracker (mat mentality)
No-excuses streak tracker for training, study, goals. Don't break the chain.
Who: athletes and grinders like you. Money: cheap subscription; sell it as a lifestyle, not a feature. Build: Easy — simple data model; the product is the attitude + design, which is your edge.
EASY★ PICK☆
'Roast my [X]' viral micro-tool
Upload setup/outfit/stats → AI roasts it, then gives real tips. Shareable = growth.
Who: teens, for the memes. Money: ads/affiliate on results, or 'pro roast' credits; viral tools sell traffic. Build: Easy — a weekend build; the whole game is making the output funny + shareable.
MEDIUM☆
Event / party hub
Create an event, collect RSVPs, split costs, share a photo wall after.
Who: teens throwing things, clubs, small organizers. Money: free core, charge for cost-splitting/payments (take a cut). Build: Medium — several small features, each a known pattern.
MEDIUM☆
Digital-product storefront
Simple store to sell presets, guides, Discord access, beats — instant delivery.
Who: teen creators selling digital goods. Money: transaction fee per sale, or a flat cheap monthly. Build: Easy–Medium — Medusa or a Stripe-payment-link starter gets you most of the way.
MEDIUM★ PICK☆
Alert bot + gated community
START HERE for finance. Bot watches conditions, pings a paid Discord/Telegram (via Whop).
Who: your trading Discord / a small community you grow. Money: paid tier + gated community via Whop (handles payments). Build: Medium — bot + free data feed (Alpaca/CoinGecko) + rules. Recommended first finance project: lowest lift, proven money rails, legally safe, teaches the build→gate→charge loop. Honest caveat: the code isn't the moat — the community is.
MEDIUM☆
Trading journal / paper tracker
Log trades, tag setups, see real win-rate & R-multiples. Prices from free Alpaca.
Who: you + Koa first, then traders who journal in messy spreadsheets. Money: freemium subscription. Build: Medium. Proven paid category (TradeZella, 50k+ traders) but crowded — only worth it with a sharp narrow wedge (one broker/asset/audience).
HARD☆
Backtest tool + paper-trading league
Define a rule, run it on history (backtesting.py), + a paper-trading leaderboard.
Who: you, Koa, and trading-curious teens. Money: indirect (community/funnel), not a standalone sub — treat as learning + audience play. Build: Medium–Hard — most technical of the three, but teaches you the most and looks the most impressive.
How to use this: pick 2–3 that pull you, then we build the first one Bartr-style — grab a template, bolt on the hands it needs, ship it live in a focused week. Volume strategy only works if each one actually ships. Star them and Claude can read your picks straight from your account.
