Codex Community Meetup × AI Tinkerers KL: Build Your SaaS with Codex Sites
Build and ship a working mini-SaaS in one evening
Codex Community Malaysia and AI Tinkerers Kuala Lumpur are bringing active builders together for a hands-on workshop focused on one outcome:
By the end of the evening, you should have a working product that another person can open, use, and test.
This is not a long product presentation, a generic AI panel, or a session where everyone watches the speaker code.
You will bring an idea, turn it into a structured build brief, create the app with Sites inside Codex, connect data or an API, test the real workflow, and deploy a shareable version.
Expect minimal slides, guided checkpoints, active building, troubleshooting, and live demos.
What is Codex Sites?
The capability is currently presented as ChatGPT Sites (https://learn.chatgpt.com/docs/sites) and can be used through Work or Codex in supported ChatGPT accounts.
Sites can help create, preview, refine, publish, and share interactive websites and lightweight applications without requiring a separate hosting workflow.
In this workshop, we will treat it as real software - not a magic landing-page generator.
That means defining:
The user and repeated problem
The core workflow
What data must persist
Product rules and permissions
Edge cases and failure states
What the agent must not change
How the result will be tested
When the app is actually ready to deploy
What you will build
Choose one focused build target.
1. Data-backed micro-app
Build a simple CRUD workflow with a small database and an admin or history view.
Possible ideas:
Volunteer shift manager
Equipment booking tracker
SME quotation follow-up board
Community event task manager
Student project approval workflow
2. API-powered dashboard
Fetch data from one external API, transform it, and turn it into a useful decision-making interface.
Possible ideas:
Public-data explorer
Grant and opportunity tracker
Local resource dashboard
Travel-planning tool
Content-performance monitor
3. File-to-insight tool
Upload a small CSV, text file, or document set and return a structured or actionable result.
Possible ideas:
Expense categoriser
Feedback analyser
Application triage tool
Document intake system
Simple reporting assistant
The goal is not to combine every idea.
The goal is to complete one useful workflow from start to finish.
What you will learn
During the session, you will learn how to:
Turn a vague product idea into a clear engineering-style prompt
Define the user, product rules, constraints, and acceptance criteria
Generate the first working application slice
Break a large implementation into smaller, verifiable stages
Connect persistent data using Sites or Supabase
Add an external REST API where relevant
Configure environment variables and secrets safely
Handle loading, empty, success, and error states
Test the actual application flow in the browser
Debug with precise reproduction steps
Review access and data handling before publishing
Save a reviewable version before deploying
Prepare and deliver a five-minute live product demo
What should be working by 9:00 PM?
Your mini-SaaS should ideally have:
One specific target user
One complete end-to-end workflow
Useful data that persists after refresh
At least one handled error or edge case
A responsive interface
No secrets committed into the source code
Synthetic or approved demonstration data
A saved and reviewed deployment version
A shareable URL
A five-minute demonstration
A smaller complete app is more valuable than five unfinished features.
Event agenda
6:30 PM - Arrival and check-in
Arrive early, set up your laptop, meet other builders, and confirm your build target.
7:00 PM - Dinner and builder matching
Solo builders may use this time to find collaborators or exchange early feedback.
7:30 PM - AI Tinkerers KL kickoff
Welcome, room briefing, and workshop expectations.
7:40 PM - Codex Sites live build
A concise walkthrough covering:
Product framing
Structured coding prompts
Sites workflow
Data and environment setup
Testing and deployment
8:00 PM - Guided build sprint
Participants build independently or in small teams, with organiser and volunteer support.
8:25 PM - Data, API, and QA checkpoint
Connect persistence, verify the primary workflow, and test failure states.
8:50 PM - Save, review, and deploy
Prepare a reviewable version, confirm access settings, and deploy the approved build.
9:00 PM - Attendee demos
Selected builders will present working products and share what others can reuse or avoid.
9:25 PM - Group photo and closing
9:30 PM - Event ends
Five-minute demo format
Builders selected to present should cover:
30 seconds - User and problem
Who is the product for, and what repeated problem does it address?
2 minutes - Live workflow
Show the user completing the core action.
45 seconds - Architecture
Explain what Sites, Supabase, storage, or an external API handled.
45 seconds - What broke
Share one bug, edge case, or incorrect assumption that had to be fixed.
30 seconds - Reusable lesson
Tell the room what another builder should copy or avoid.
The most valuable demo is not necessarily the most polished one. Show us what works, what failed, and what you learned.
Who this is for
This workshop is designed for:
Software developers and engineers
Technical founders
AI and machine-learning practitioners
Product designers who can work with code
Students actively building technical projects
Data professionals creating internal tools
Builders already experimenting with coding agents
People bringing a specific workflow they want to improve
Basic coding experience will help, but you do not need to be an expert.
You should be comfortable following technical instructions, reviewing generated code or application behaviour, and troubleshooting with support.
What to bring
Required:
Laptop and charger
Reliable browser
Latest ChatGPT desktop app or access to ChatGPT on the web
One focused product idea
Small synthetic sample data where relevant
A small comfort tip 🧥
We recommend bringing a light sweater, hoodie, or jacket just in case so you can stay comfortable while building.
Strongly recommended:
A free Supabase account
GitHub account
A public REST API selected in advance, if building an API dashboard
A small CSV or text file, if building a file-to-insight tool
LinkedIn, GitHub, X, or personal website added to your RSVP profile
Data and security guidance
For this workshop:
Use synthetic, public, or explicitly approved data
Do not upload real customer exports
Do not use protected health information
Do not use payment-card information
Do not paste API secrets into prompts or source files
Do not expose administrative or service-role keys in browser code
Keep a Site private while reviewing it
Confirm the intended audience before publishing
Participants remain responsible for the data, integrations, and third-party services used in their projects.
Registration and approval
Space is limited and applications will be reviewed.
Submitting an application does not guarantee admission.
Registration workflow
Luma is the primary public registration and event check-in source.
Approved participants will also be asked to complete the linked AI Tinkerers Kuala Lumpur registration step so AITKL can manage its local member notification and attendance records.
Both steps must be completed for final confirmation.
AI Tinkerers KL registration:
Event credits
Potential Codex and Supabase build credits are currently subject to final partner confirmation, eligibility requirements, and physical event check-in.
Registration does not guarantee credits.
Any confirmed credit distribution details will be shared privately with eligible participants. Individual redemption links or allocations must not be transferred or posted publicly.

Final reminder
Do not come only to hear what Codex Sites can do.
Come with a real problem.
Build the smallest useful version.
Test it with another person.
Then show the room what worked - and what did not.
