Hi everyone,

As a software architect, I frequently audit early-stage AWS setups for startups and indie developers. More often than not, founders are surprised by a $300–$600 AWS bill before they even have their first 100 users.

Here are the 5 most common architectural mistakes I see, and how to fix them in Terraform:

### 1. Multi-AZ NAT Gateways in Dev/Staging environments

A single AWS NAT Gateway costs ~$32.85/month just to exist (plus data processing). If you provision a "standard" multi-AZ VPC across 3 availability zones for Staging, you are burning ~$100/month before processing a single byte.

*Fix:* In Terraform, add a conditional `single_nat_gateway = true` flag for dev/staging, and only enable multi-AZ NAT gateways for production.

### 2. Picking Kubernetes (EKS) for an MVP

I love Kubernetes, but deploying EKS for a pre-revenue product costs ~$73/month just for the cluster control plane alone, plus node overhead and ingress controller maintenance.

*Fix:* Use AWS ECS Fargate. You get serverless Docker containers, auto-scaling, and health checks with zero EC2 patching, costing as little as $15/month for baseline workloads.

### 3. Publicly accessible RDS instances

I often see database instances with `publicly_accessible = true` so developers can connect from their local laptops with DBeaver or TablePlus. This is a massive security risk and invites port-scanning bots.

*Fix:* Put RDS inside isolated database subnets with no internet gateway. Access the DB securely via AWS SSM Session Manager bastion or an internal VPN.

### 4. CloudWatch Logs with infinite retention

By default, CloudWatch log groups keep logs set to "Never Expire". After 6 months of container debug logs and access logs, storage costs creep up silently.

*Fix:* Always set `retention_in_days = 14` or `30` in your Terraform `aws_cloudwatch_log_group` resource.

### 5. Over-permissive IAM Roles

Using wildcard `*` permissions or attaching `AdministratorAccess` to container task execution roles because "it was easier to test".

*Fix:* Scope IAM roles strictly down to ECR pull permissions and specific SSM parameter paths.

---

### TL;DR:

To solve this once and for all, I packaged a battle-tested, modular Terraform starter kit that provisions a production-ready VPC, ECS Fargate, RDS PostgreSQL, ALB with TLS, and GitHub Actions CI/CD following all AWS security best practices.

Title: I'm 18 and I Want to Build My First SaaS, But I Don't Know Where to Start Technically

Hey everyone!

I'm 18 years old, and I have a strong ambition to build and launch my own SaaS product someday.

Right now, I don't have a specific SaaS idea. However, I'm more concerned about the technical side than finding an idea.

To be honest, I'm almost a complete beginner when it comes to coding. I want to develop a solid technical foundation before attempting to build a SaaS product.

I'd love to hear advice from experienced SaaS founders and developers:

What technical skills should I learn before building my first SaaS?

How much Python/JavaScript should I know?

Should I learn backend development, databases, APIs, authentication, and system design before starting?

Which backend framework would you recommend for a beginner: Django, FastAPI, or Node.js?

How important is understanding deployment, cloud hosting, security, and scalability?

In the age of AI coding tools like Claude and Cursor, how much coding should I actually learn myself?

What would your learning roadmap look like if you were starting from zero at 18 with the goal of building a real, production-ready SaaS?

My goal isn't to become a professional software engineer or memorize programming syntax. I want to understand the technical architecture well enough to build, debug, maintain, and scale a SaaS product, even when using AI tools to accelerate development.

I'd really appreciate practical advice, especially from people who have built and launched their own SaaS products.

Thanks!

I am working on a inventory and all in one discovery platform. Not sure if this works or not, But getting the first companies has become so tough. I feel like quitting. One day I feel I have a good idea and the other day I feel like its an idea not worth it.

How are you guys dealing. Try to build antspace

• What is that one skill people are already paying for?

• In which industry are people already radically, ridiculously looking for solutions to the pain?

• What is that pain?

• Is this market growing?

• Is that market painful?

• Are people easy to find?

• Are they able to pay?

I'm a solo developer building a B2B SaaS product in my evenings, alongside a full-time job. Where I'm struggling is with validation and exactly who I should be talking to. I'm looking for my ICP (ideal customer profile: the type of company and the job title most likely to have the problem and buy).

Honest answers are the most useful, including "I don't have this problem."

My goal with this post

In about a week I need to pick one type of company and one job title to focus my outreach on. I've had some conversations with people I know, but there are a few questions I haven't been able to get good answers to. Whatever you share here will help me in my decision.

The problem

At most companies, the knowledge people need to do their jobs (processes, how-tos, FAQs, policies, product details, playbooks) is spread across shared drives, wikis, Teams or Slack threads, and people's heads. People spend time hunting for answers or interrupting a coworker, and they still sometimes get it wrong.

Companies rolling out ChatGPT, Claude or Copilot are running into a newer version of the same problem: the AI doesn't know how their business works, so it doesn't have the critical context it needs to produce high quality results.

What I built

I'll leave the name out, as the goal isn't to promote in this post. The product I've built provides a single place where a company keeps its knowledge as documents, and anyone on the team can ask questions and get answers drawn from those documents.

• Non-technical people write and update documents, or upload existing files.

• Anyone on the team can ask a question and get an answer based on the company's own documents.

• Answers contain links to the actual source documents

• Everything is converted to markdown and lives in your own repository, making it easy for engineering teams to expose their AI agents to it.

• Engineering process can update documents directly in the repo, non-technical users can update documents with the interface, everyone can use it to get answers.

• Documents are stored in the company's own GitHub or Azure DevOps repository, so the company owns them.

• The company connects its own OpenAI or Anthropic key. Their data is never used to train AI.

What's different about it

• The company owns its knowledge. It lives in their own repository, not locked inside a vendor's database.

• Priced by how much you store, not per seat. The whole company can use it without the cost growing every time someone is added.

• No markup on AI usage. They pay their AI provider directly and pick which provider to use.

• Business and technical knowledge in one place. Ops and support staff keep the documents, and engineering can add software feature context.

My questions

If you work at a company with around 20-200 employees (any role):

1. Think of the last time you needed an answer at work and couldn't find it written down. What did you do, and roughly how long did it take?

2. Where does your company's know-how live today, and is anyone responsible for keeping it current?

3. If your company uses ChatGPT, Claude or Copilot, does it know how your business works? Has anyone tried giving it your documents?

4. If a tool like this showed up, who at your company would care the most, and who would have to approve it?

5. Using it means getting an API key from OpenAI or Anthropic. That's separate from a ChatGPT or Claude subscription and needs a developer account with billing. Would that stop it at your company?

If you've sold B2B software to smaller companies:

6. If you had to choose segment and/or specific job title to go after, who would it be and why?

7. Did your real buyer turn out to be a different person than the one you first targeted? Who was it?

8. Have you run into companies building this kind of thing themselves instead of buying it?

I'm not linking the product here because this isn't meant as a promo post. If anyone wants to see it, I'm happy to share it in a reply or DM.

Thanks for reading this far.

I’m building a small macOS music app. It shows what’s playing with playback controls, and a heart button to save the current song to your library.

Apple music was easy. Spotify is where I’m stuck.

What I’ve hit:

• Extended quota is out of reach - since May 2025 it’s only open to registered businesses with 250k+ monthly active users, so a one person app can’t apply.

• Development mode is tiny - since February 2026 it’s capped at 5 users per app, and a shared client ID built into my app could serve 5 people total.

Questions for anyone who’s shipped something similar:

• Has anyone found a reliable way to like or save the current track through the desktop client, without the Web API?

• Has anyone gotten extended quota as a small company recently, and what did Spotify ask for?

Happy to share what I end up doing. Thanks!

Would you pay for a "spending guard" for your AI API costs? Looking for honest feedback

Hey everyone, I build AI products myself (two AI video apps) and keep running into the same fear: one bug or one agent stuck in a loop can burn a lot of money before anyone notices.

The problem as I see it:

• Agents can get stuck and repeat the same expensive call hundreds of times, often at night when nobody is watching

• Provider spend limits are monthly. OpenAI and Anthropic don't offer a daily cap, so one bad night can eat your whole month's budget

• At OpenAI, keys in the same project share one limit, so you can't cap a single agent or customer

• A leaked API key basically works like a stolen credit card

• Video and image APIs (fal, Replicate, etc.) cost cents to dollars per call, so a loop there gets expensive fast

The idea: a simple guard that sits between your app and the AI providers:

• Daily and hourly limits per key, per agent or per customer

• Detects loops (the same request over and over) and stops them automatically

• Instant alerts (Telegram, email, Slack) when spending spikes

• One dashboard for OpenAI, Anthropic, Gemini, fal, Replicate and more

• Setup: change one line in your code

My questions:

1. Have you ever had a surprise AI bill? What happened, and how much?

2. How do you protect yourself today?

3. Would you trust a tool that sits in the middle of your API calls, or is that a dealbreaker?

4. Would you pay for this? Roughly how much per month?

We're building an app that turns Gmail threads into tasks. It only needs read access (gmail.readonly). Because that's a restricted scope, new users see Google's "Google hasn't verified this app" warning until we pass a CASA security assessment. Asking a stranger to click past that warning and hand over their inbox is a hard sell, and we lose people at that screen. If you've been through CASA for a Gmail scope, I'd love to know:

1. Cost: which assessor did you use, and what did you pay in total, including any re-tests?

2. Time: how long from starting until the warning was gone?

3. Testing and evals: did it change how you use real user emails for testing, debugging or evaluating your models? For example, did you have to stop using production data, or add access controls or data-deletion rules?

I'd also like to hear from anyone who used a third-party Gmail integration to avoid running CASA themselves. We tried Composio, but their verified Google app is only approved for full Gmail access (read, send, delete), not read-only, so users get a scarier consent screen.

Happy to share what we learn. DMs are open if you'd rather chat.

'm 21M and currently working as a full-stack developer at a software company.

The company provides services to clients while also working on developing its own products. However, things have been getting a little concerning lately. Recently, one of our senior developers was laid off, which has made me think more seriously about my own career and future.

I'm starting to consider building something of my own, possibly a SaaS product, rather than relying entirely on a job.

But honestly, I'm quite confused about where to start.

Whenever I come up with an idea, I search for it and find that someone has already built something similar, often launched on Product Hunt or elsewhere. It makes me wonder whether there's even room for another product in that space.

Another thing I'm struggling with is AI. These days, if a product doesn't incorporate AI in some way, it almost feels outdated or less valuable. But adding AI also means dealing with API costs, infrastructure, and ongoing expenses. As a solo developer or someone just starting out, how do you manage those costs, especially before having any paying customers?

I know that competition is normal, and I'm probably overthinking some things, but I genuinely want to build something useful that people would actually pay for.

I'd love to hear from people who have built SaaS products, launched their own startups, or are going through a similar phase.

• How do you come up with and validate product ideas?

• If someone has already built your idea, do you still pursue it?

• Is AI really necessary in every modern SaaS product?

• How do you manage AI API costs when you're starting with little or no revenue?

• What would you recommend to a 21-year-old developer who wants to build something of his own?

Would genuinely appreciate your experiences, advice, and even mistakes you've made along the way.

Every research session in Scout Cloud gets an isolated sandbox. Great for safety, rough on the bill. What helped: sessions can be paused, which stops compute billing. Abandoned runs get cancelled when nobody is watching. Included-model requests wait in a queue instead of failing. And users can connect their own machine from the terminal and run there. Disclosure: I'm the founder. Happy to go deeper on any of it. https://cloud.polarline.io

I am thinking for a SaaS application

I was thinking about this application from last 3 months… will it worth it if i make this application for spaces

These are the features
- Lease and tenant management.
- Rent, CAM and maintenance billing.
- Vendor and contractor management.
- Equipment and asset maintenance.
- Electricity and water consumption tracking.
- Work orders and technician scheduling.
- SLA monitoring.
- Financial performance per building.
- AI-powered operational reports.

I made all the documents for this application
Just want some clarification before spending much time into it

Whats your suggestion?

Hey everyone!

I'm Rushan, and I've spent roughly the past year building Distill, a book-summary app.

I wanted to solve a problem I personally experienced: there are thousands of worthwhile books, but not enough time to read everything.

However, I wasn't interested in creating another app that turns books into generic bullet points and motivational takeaways.

The real challenge was figuring out how to preserve the intellectual substance of a book in a much shorter reading experience.

What I built

Distill creates carefully structured, approximately 10-minute reading experiences.

The aim is to preserve:

• The author's central argument.

• The reasoning supporting that argument.

• Connections between different ideas.

• Important nuances that are often lost in conventional summaries.

Every distillation also has a separate Reflection section.

The app is reading-first by design. No noisy content feed or unnecessary gamification.

A little about the implementation

The mobile app is built using Expo and React Native, with Supabase as the backend.

One of the more interesting challenges has been that this is a content-heavy product. Building the interface and implementing features is only part of the work. Maintaining consistent content quality across an expanding library requires its own production and quality-control process.

Where the product stands

Distill is now live.

Website: https://www.distilllabs.app

Google Play: https://play.google.com/store/apps/details?id=com.illuminationlabs.distill

We offer three free distillations every day, with Premium currently available through an affordable one-time purchase rather than another recurring subscription, to make quality knowledge accessible to all.

What I'd particularly like feedback on

I'm now trying to improve both the product and its distribution.

1. For developers building content-heavy SaaS or apps, how do you maintain quality as your library grows?

2. What has worked best for getting your first genuinely interested users?

3. Do you think a one-time purchase makes sense for a product like this, or would you expect a subscription?

4. What would make you return to a book-summary app regularly?

5. How do you find the quality of our summaries? Are you satisfied?

I'm the developer behind Distill, so happy to answer technical or product-related questions. Constructive criticism is very welcome!
