"The reality is, when you're optimizing for production, you start looking at a price/performance," Guillermo Rauch tells TechCrunch.

I created this post for the purposes of entering the H0: Hack the Zero Stack with Vercel v0 and AWS Databases hackathon. #H0Hackathon Inspiration — this one's personal This started with my daughter. She's 13 and an aspiring actor — she's already worked on campaigns and shows from national commercials to a children's TV show, and walked NYC and Brooklyn fashion shows. Every time we went to an audition or recorded a self-tape, I saw how disconnected the whole process was: submissions over email, schedules buried in texts, files scattered across folders, and no clear view of where anything actually stood. I started talking to talent agencies in New York and LA, and they all said the same thing — they're still managing their talent by hand, and it doesn't scale. That's why I built Quudos. The problem Talent agencies run casting on a patchwork of spreadsheets, email threads, shared folders, and disconnected casting databases. Submissions get lost, callbacks slip, and there's no single place to see a campaign move from breakdown to booking. Quudos is the all-in-one operating system for talent agencies — manage your roster, launch casting campaigns, and track every submission through callback and booking. For this hackathon I put it on the zero stack : a front end on Vercel and Amazon Aurora PostgreSQL as the primary database. The architecture Frontend: an Angular single-page app on Vercel , with a v0-built marketing landing page in front of it. API: a NestJS (Node) service using node-postgres with pooling, transactions, and advisory locks. Primary database: Amazon Aurora PostgreSQL (Serverless v2) in us-east-1 — the system of record for every agency, talent profile, campaign, role, submission, and lifecycle event. Auth: a managed auth provider issues JWTs that the API verifies; all application data lives in Aurora. Why Aurora — and a deliberate data model Casting is inherently relational, so I modeled it that way: organizations (agencies) → users (admins + talent) → actor

I built this project as an entry for the H0: Hack the Zero Stack with Vercel v0 and AWS Databases Hackathon. #H0Hackathon Inspiration Justice moves slowly. I learned that firsthand as my family navigated a legal dispute. What struck me wasn't just the stress — it was that things were quite disorganised. Documents were paper-based or buried somewhere in emails. Updates came through WhatsApp messages. Simple documents took a really long time to draft and send. The system was fragmented and difficult to navigate. Companies like Harvey tackle document drafting well, but legal research tools and LLM wrappers can hallucinate case law, citing judgments that don't exist. I knew that if I was going to build something for this space, it had to be grounded in real, verifiable law. That led me to Laws Africa, which provides structured access to actual South African legislation and court judgments. I also noticed a problem that lawyers experience daily: the mechanical work. Logging into court portals to file a case. Hunting through OneDrive, Google Drive, and Dropbox for the right version of a document. Sifting through hundreds of emails to find something relevant to a matter. Onboarding a new client when the intake form is a PDF someone emails you. These are not AI problems. They are automation problems — and lawyers or their secretaries are doing them manually every single day. That became Agently. What Agently Does Agently is a legal workspace that handles the full lifecycle of a matter, from the moment a client submits an intake form to the day the case closes. Matter Management. Every client engagement lives in a structured matter. Documents, emails, notes, contacts, workflows, and AI conversations are all scoped to it. A lawyer can open a matter and immediately see everything relevant. AI Agent with Real Legal Research. The AI connects to Laws Africa's knowledge bases — South African legislation, court judgments, and municipal law — so research is grounded in actual legal

TL;DR If the Vercel CLI keeps trying to open a dev link against your Vercel project during local next dev runs, set VERCEL_EXPERIMENTAL_DEV_SKIP_LINK=1 in the shell that launches the dev server, or add it to .env.local at the project root, and restart the process. The flag is opt-in, all-uppercase, and only affects local CLI behaviour. It never reaches your deployed build, and the production runtime on Vercel does not read it. If the CLI still tries to link after a restart, scroll to Debugging when the skip link isn't working for the version-compatibility and process-tree checks that catch the cases the basic setup misses. I have shipped this flag in three production monorepos and the same four mistakes account for almost every "I set it and it did nothing" report I see. What VERCEL_EXPERIMENTAL_DEV_SKIP_LINK actually does VERCEL_EXPERIMENTAL_DEV_SKIP_LINK is an opt-in environment variable the Vercel CLI honours when it runs alongside a local Next.js dev server. Its job is narrow: tell the CLI to skip the step where it would normally reach out to Vercel and create or refresh a dev link against your Vercel project. A "dev link", in the Vercel sense, is a local connection record that lets vercel dev and some Vercel-only local emulators (KV, Postgres, Edge Config) pull real values from a Vercel project. It is useful when you want production-shaped data during development, and a real annoyance when you do not — for example in CI sandboxes, offline laptops, monorepo workspaces that share a single project, or any time you want next dev to behave like a plain Node process without the CLI wrapping it. The variable is shipped under the VERCEL_EXPERIMENTAL_ namespace, which Vercel uses to mark features that can change between CLI versions. That has two practical consequences: the name must be uppercase with underscores, and you should not build production logic on top of it. I treat it like a local-dev knob, set per shell session, and never check it into CI as a hard dependen

TL;DR for vibe coders: Shipped an app with Cursor, Claude Code, or v0 and got a scary Vercel or Neon bill? You probably don't need a bigger plan. You need a few fixes. Not technical? Copy the agent-rules folder from the companion repo into your project and tell your AI editor "apply these cost rules." That's the whole job. You don't need Vercel Pro. You don't need to "Launch" on Neon. A lot of the time you need the opposite of an upgrade. You need your stack to go to sleep. Here's the moment that started this. A Neon bill landed, across three small Next.js apps running on Vercel with a Neon Postgres database, and the breakdown was lopsided in a way that gave the whole game away. $32.65 of it was compute. Storage was 5 cents. History and data transfer were zero. The meter said 308 hours of compute time in about three weeks, which is a database awake for roughly fifteen hours a day, every day. The instinct when a bill climbs is "I must be getting traffic, time for a bigger plan." So before doing that, I opened Google Analytics. Zero users in the last 30 minutes. Meanwhile the database compute was pinned active, and had been more or less around the clock. So this was never a storage problem or a traffic problem. Almost the entire bill was one thing: paying for a database to stay awake doing nothing. Both of those things were true at the same time, and here's the part I'll say up front so nobody has to guess: I didn't hand-write the mistakes that caused this. AI coding agents did. I described features, the agent shipped working code, and that code carried a handful of patterns that quietly defeat scale-to-zero. That's not a confession of bad engineering. It's just what building looks like in 2026. Most of us are vibe-coding onto serverless and cloud infra now, and the agent optimizes for "make the feature work," not "keep the database asleep when no one's around." It has no idea your compute bills by the hour it stays awake, so it has no reason to care. That's the whole

How I Built a Real-Time Bounty Marketplace with Supabase and 14-Layer Edge Security I wanted to build a platform where anyone can post a task (a "bounty"), set a reward, and have people complete it with verifiable proof. Think freelance work, but optimized for quick, composable task completion — with proof submission as the core trust mechanism. The result is BountyClaimer — a real-time marketplace running on Supabase + Vercel with a security system baked into Edge middleware and scattered across every layer of the stack. 🛠️ The Tech Stack Frontend: React + Vite + TypeScript Backend: Supabase (PostgreSQL, Realtime, Storage, Auth) Payments: Stripe Hosting: Vercel (Edge Middleware) Security: Custom "Armadillo" system (14 layers) Architecture Pattern: Phoenix Architecture for real-time state consistency 🔄 The Core Workflow Post — A user posts a bounty with a reward and description Claim — Others browse and claim available bounties Submit — The claimer completes the work and submits proof (images, video, audio, text, files) Settle — The bounty owner reviews and approves — funds are released Sync — Real-time updates keep both sides in sync instantly The hardest parts were real-time state sync across multiple users , anti-abuse without hurting legitimate users , and security at the edge . 🏛️ The Phoenix Architecture One pattern I'm particularly proud of is what I call the Phoenix Architecture — a real-time state management approach that ensures every client sees the same truth without polling. The core idea: instead of each client fetching data and hoping it's current, database changes (bounty status updates, proof submissions, claim state transitions) are broadcast out via Supabase Realtime. Every connected client receives the same event stream and updates locally. // The Phoenix pattern — subscribe to changes once, // update locally from the event stream const channel = supabase . channel ( `entity- ${ id } ` ) . on ( ' postgres_changes ' , { event : ' * ' , schema : '

I built InvoiceAI an AI powered invoice generator that lets you describe what you want to invoice in plain English and get a fully formatted invoice in seconds, complete with PDF download and a real payment link. Here's how I built it for the #H0Hackathon. The Problem Freelancers and small businesses waste time manually creating invoices. You know what you did, who you did it for, and how much it costs you shouldn't have to fill out a form to capture that. The Stack - Vercel v0 — scaffolded the entire UI in one prompt Next.js 16 — framework Groq (Llama 3.3 70B) — AI natural language to invoice fields AWS DynamoDB — stores every generated invoice Paystack — generates real payment links jsPDF — client-side PDF generation Vercel — deployment How It Works User types: "50 hours of mobile app development at $80/hr for TechLagos Ltd, 7.5% VAT" Groq parses the text and extracts structured invoice data Live preview updates instantly User downloads PDF — invoice is saved to DynamoDB automatically One click generates a real Paystack payment link to send to the client Building the UI with v0 I used Vercel v0 to scaffold the entire UI in one prompt. It generated a production-ready Next.js component with a split-panel layout form on the left, live invoice preview on the right. I just had to wire up the AI and database logic. Connecting AWS DynamoDB Using the AWS SDK v3, I connected DynamoDB directly from Next.js server actions. Every time a user downloads an invoice, it's saved to DynamoDB with the client details, line items, tax rate, and timestamp. This gives the app a real data foundation that scales from day one. await dynamo . send ( new PutCommand ({ TableName : ' invoices ' , Item : { invoiceId : data . invoiceNumber , clientName : data . clientName , clientEmail : data . clientEmail , items : data . items , createdAt : new Date (). toISOString (), }, })) The Result AI generates invoice from plain English in under 2 seconds Real PDF download (no print dialog) Real Paystack

Vercel's built-in cron triggers your serverless functions on a schedule. For simple use cases it works. But it has no failure alerts, no execution history on the Hobby plan, and no way to know whether your function actually completed successfully — only that it was called. Where Vercel cron falls short Vercel cron works by invoking one of your API routes on a schedule defined in vercel.json . The invocation is fire-and-forget — if your function times out, throws an error, or returns a non-2xx status, you get no alert. You find out when a user reports something is broken. The specific gaps developers run into: No failure alerts. Vercel does not send an email or webhook if your scheduled function fails. No execution history on Hobby. The free plan does not retain cron execution history. Timeout ceiling. Functions are subject to the same timeout limits as all serverless functions — 10 seconds on Hobby, up to 300 seconds on Pro. HTTP-only. Vercel cron calls an HTTP endpoint on your app. You cannot schedule arbitrary background work outside your deployment. No heartbeat monitoring. Even if your function is called successfully, you have no built-in way to verify it completed its work — only that it was invoked. Minimum 1-hour interval on Hobby. Sub-hourly schedules require a paid plan. If you are hitting any of these limitations, you need an external tool.
