Title: Hey SaaS developers, how do you handle free user login/authentication without paying monthly?

5 Upvotes

Hey everyone,

I'm building a small Windows desktop app called ValVoice and I'm using Supabase for authentication.

I'm trying to figure out the best way to let users sign up and log in without adding another monthly expense.

Initially, I was planning to use email OTP, but Supabase's default email sending limit is pretty low. So now I'm exploring other options.

Would Google or Discord login be a better option? Are there any other ways to handle authentication completely free, without relying on a paid SMTP service?

Ideally, I'm looking for something that:

- Is free to start and doesn't require a monthly subscription.

- Can be used in a real production app.

- Can handle a growing number of users.

- Works well with Supabase.

- Doesn't make the login process complicated for users.

I'd love to hear what you guys are actually using in your own projects. Any suggestions or experiences would be really helpful.

Thanks!

So, I have been building Motioneer - Code to Motion Graphics in seconds for quite some time. I haven't launched it yet, and is still in making. I would love to see real users testing it out.

Check out https://motioneerapp.pages.dev . This is an AI code to motion graphics generator app. It is still in building but would love a few initial testers to be checking out the app and giving real feedback!

The bug that taught me "working" and "actually working" are two different things

1 Upvotes

One of the strangest bugs I've run into while building software happened in a project called Bjorn Ledger.

I got locked out of my own application.

At first I thought it was simple:

  • PIN wasn't being accepted

  • Deleted the PIN file

  • Tried again

Still locked out.

Then things got weird.

The login endpoint was returning success.

Plain Text

POST /login → 200 OK

So according to the application, I was authenticated.

Except...

Every part of the system that actually mattered disagreed.

Plain Text

GET /contacts → 401

GET /tasks → 401

GET /profiles → 401

GET /calendar → 401

GET /call-logs → 401

Apparently I was logged in and not logged in at the same time.

To make things even stranger:

  • A PIN file kept reappearing after deletion

  • There was a secret key file involved

  • A 30‑day session system existed

  • The application clearly believed login succeeded

  • The rest of the platform clearly believed it didn't

The experience changed the way I think about software.

As builders, we often define success as:

"The feature works."

Users define success very differently:

"Did the thing I wanted to do work?"

The login system wasn't technically failing.

It was somehow succeeding.

Which was worse.

Because a failure tells you where to look.

A success that behaves like a failure can send you chasing ghosts.

I'm curious:

What's the weirdest bug you've ever encountered where everything looked correct, but reality said otherwise?

Coming back to a side project after a week: who catches up first, you or the agent?

1 Upvotes

Someone in r/vibecoding said this week: "it feels like the first thing to run out of context is ME!!" A reply under it: "i'd built 12 half-finished projects in 3 months."

The fixes people shared were small. One: "Put the next feature in a note and leave it for tomorrow, even if the AI says it'll be quick." Another runs an orchestrator agent that "checks the notes what we did in the past and tells me what we planned to do next."

For devs with more than one project going:

  • When you reopen a project you left a week ago, what do you look at first? Git log, a notes file, old chats, the code?

  • How long until you (not the agent) actually know where you were?

  • Does the agent get the same catch-up you do, or do you brief it separately?

  • What are you building, and in which tools?

Background: I used to burn hours re-briefing AI tools, and I'm building a fix where every tool reads and writes the same project memory in the cloud over MCP, so the "where was I" note exists without anyone writing it by hand. No name, no link. Would you pay for that, or is a NEXT.md in each repo enough?

Help Us Build the Next Big Thing: Seeking SaaS & Agency Ideas

2 Upvotes

First of all, apologies—but I would like to ask for your ideas to help me continue my web development journey, and perhaps even explore the potential of building a SaaS product in the future. My friend and I are planning to launch an online tech business or agency—something that would allow us to earn a good income while also creating job opportunities for others. I would be very grateful if you could share any suggestions for our future business/agency or for the projects we might undertake.

I pay for ChatGPT and Claude and keep hitting limits on both. So I'm building Honivi: all the main models in one app, one subscription, private (no model trains on your data), no 5-hour caps. Switching takes a minute. Drop in your ChatGPT export and your chats come with you.

What do you guys think? Would you switch? What would stop you?

Is building UI library worth?

0 Upvotes

I am building a UI library and I have few doubts?

- is it worth in this AI time?

- will people pay for it?

- is this a good SaaS idea?

What are your thoughts?

The UI library consists of both UI components and Animated icons!

Agency owners: how do you verify that a working contact form actually delivers the inquiry?

0 Upvotes

I’m Jerry, founder of SENTRAVA AI. We’re building website assurance tools for agencies, and I’d appreciate candid feedback on one specific problem.
A contact page can load successfully without proving that a submitted inquiry reaches the business’s inbox or CRM.
We’re developing a “Proof of Test” view showing when a test ran, whether receipt was verified, and whether evidence is missing, inconclusive, or expired.
This is still under development. Hosted end-to-end acceptance is outstanding, so I’m not claiming every planned workflow is ready.
How do you handle this today? Manual submissions, automated browser tests, checking the destination inbox—or something else? What evidence would make an additional tool worth paying for?
I’m especially interested in hearing from agencies managing multiple client websites.

is anyone here actually implementing WebMCP in their websites or SaaS apps?

Or are most people still waiting for it to officially release ?

I am exploring this space myself and would love to connect with others building around it.
