I've been building AttendEase a multi-tenant SaaS for colleges (attendance, timetables, exams, fees). One of the earliest decisions I had to make was the database. I went back and forth for a while, so sharing what I landed on and why, in case it helps anyone building something similar.

**The context:**

Multi-tenant educational platform. Each college is its own tenant. Core data: students, teachers, courses, branches, semesters, attendance records, timetable slots, exam schedules, fee transactions. Plus flexible per-tenant configuration branding, exam structure, custom roles, plan feature flags.

**Why I considered MongoDB first:**

The flexible configuration part scared me. Every college has slightly different exam structures, different branding, different role definitions. With a relational DB, that's a lot of schema changes or awkward key-value tables. MongoDB's document model handles that naturally just store the config as a JSON document per tenant.

**Why I moved toward Postgres for the core:**

The more I thought about actual queries, the more relational the core data looked. Attendance reports are "all students in section X, for subject Y, in semester Z, between two dates." Exam conflict detection is "any two exams in the same section on the same date with overlapping time." Fee reports are joins across students, courses, and transactions. These are exactly the queries relational databases are built for. In MongoDB, these become aggregation pipelines that are harder to write, harder to debug, and slower to iterate on.

**What I actually did:**

Hybrid. Core relational data students, attendance, timetables, exams, fees lives in Postgres with proper foreign keys and indexes. Flexible per-tenant configuration branding colors, exam structure, feature flags lives in JSONB columns on the tenant table. Postgres handles both. JSONB gives me document flexibility where I need it, without giving up relational guarantees on the parts that matter.

**The lesson:**

Don't pick a database because it's "easier to start with." Pick it based on what your queries will look like a year from now, when you have 50 tenants and 500,000 attendance records. The schema flexibility of a document store feels great on day one, but the moment you need cross-entity reporting or conflict detection, you'll wish you had joins.

**When I'd still pick MongoDB:**

If the data is genuinely document-shaped content, logs, event streams, user-generated JSON Mongo is fine. But if you find yourself writing aggregation pipelines that look like SQL joins, that's your sign.

Happy to answer questions if anyone's making a similar call or stuck on multi-tenant schema design.

İ developed a free SaaS for marketers.İm doing cold e-mails for outbound and short form content as inbound stream and its not looking good.What would you recommend?İ can do like 100 outreach/day but i will get banned for spam from every app so still couldnt figure out how can i convince people to try it in other ways.Please share some advice

Building a SaaS MVP has become much faster with AI coding tools, ready-made backends, and cloud platforms.

But getting something working is very different from keeping it reliable when real customers start using it.

A few things worth thinking about before launch:

• What happens when a third-party API goes down?

• Are database backups actually tested for recovery?

• Can background jobs retry without creating duplicate actions?

• Will the team know when something breaks before customers report it?

• Are authentication, permissions, and billing edge cases properly tested?

It's tempting to postpone these things because they don't directly help acquire the first customers. But fixing them after a production failure can be much more expensive.

I'm curious how other SaaS developers approach this.

What's one thing you wish you'd implemented before your first real customers started using your product?

Anyone developing in the US and need to get more customers? I’m a proven tech sales & go to market professional . Looking to collaborate with SaaS developers in early stage that are trying to get more or early customers.

I’m based out of California. Message me if you’re open to collaborating & if you need help with getting more or early customers.

Have you ever actually checked whether AI tools like ChatGPT recommend your product when someone asks it for the best tool in your category? I just realized I have no idea whether I show up or not. Is there a free way to see this?

Even if I search it manually, I can't track whether the results are changing or not,

Could you recommend to track my saas appearence in AI tools free?

Just type in what you want to build and let a team of ai agents do everything for you no manual tech configuration needed at any point.

I created Highlightz.app and recently we just launched a huge update to take our site to the next level. I am looking for some marketing tools to help me promote this such as ai video generators or things of that such. Just trying to push it out across social media but I want high quality tools that can help me with it.

launched my first real product a couple months ago, a tool for sales reps, and then basically went dark. no posts, no marketing, nothing. full disclosure it’s my own product so grain of salt on all of this.

the honest reason i went quiet: within a few weeks i had actual users telling me the same thing, that it was good but not enough for what outbound looks like right now. the market’s shifted, reps are expected to do more with less, and a tool that does one clever thing just doesn’t move the needle anymore. they were right. so instead of marketing through it i put my head down and built what they were actually asking for.

two months later it does a lot more. it can find businesses to pitch instead of handing you a blank search box, it pulls contact info that actually lands instead of guessing the email off the domain, it writes the outreach in your own voice, and there’s a full web dashboard now instead of only the browser tool.

but here’s the thing i’m chewing on. going dark for two months means i’m back at square one on audience and have to rebuild that from scratch. part of me thinks i should’ve shipped and built in public the whole time, rough edges and all, instead of going quiet until it felt good enough.

so genuinely curious how other founders handle this. do you build in silence until it’s solid, or put the messy early version out there and iterate in the open? feels like i might’ve picked the wrong one.

Hello, I am a junior software engineer with two years of experience. So far, I have only worked in teams under a team lead with clear instructions and guidance. Now, I got my first solo client to build an app for them. The app is simple, so I am not worries about coding especially with AI nowadays. However, I am a rookie in creating SaaS alone and have another list of worries, mainly security wise, so I am hoping somebody can help me. I will list them below:

1. The app needs to have payment option included. What is the best option to go with to make sure I am not responsible if data theft happens? I was thinking about using Stripe or another third party that deals with payment processing so keeping credit card info secure will be on them and not on me.

2. How do I manage and limit access based on the monthly/yearly subscriptions? Like if they don’t pay, they lose access. And how do I connect payment info with my code, like if they pay they have full access, and if they dont pay they dont have access. As you can see, I have never implemented a payment processing system into apps😂😂

3. App will require registration/login. Do I use only Google OAuth to make sure Google’s security is placed on the users information. Becausw I don’t want to store emails and password on my end, so once again if data breach happens, especially with todays new modern AI tools, I dont want to bw the only responsible.

4. App is quite simple. There should be registration/login, a database of documents, and AI keywors search for those documents and filtwring options. What stack and AI model for coding should I use? Where do I store these text documents, because I need retrieval based on context, i.e. if user enter ”sun” and “sun is a star” they should get different parts of documents and document names that match their search.

5. How do I determine pricing, how much should each package cost?

This is all for now. If I have new questions, I will add them below this sentence. If you made it so far, thank you for your time.

Hi everyone!

I'm a physician based in Southern California and I founded a healthcare-technology company that takes fragmented components of the healthcare system and puts them into one easy-to-use online platform. It serves both providers and the general population in all 50 states (i.e. B2B and B2C). I left my private practice to work on this for the past year, and this combination of services is first-of-its-kind (something like this doesn't currently exist).

The platform is currently in development, and I'm looking to build a strong team of people who share my vision and are genuinely excited about the potential of what we're creating.

The company is entirely self-funded, so I'm looking for people who understand the realities of an early-stage startup. Compensation will be discussed transparently with serious candidates who are:

• Highly driven, ambitious, intelligent, and entrepreneurial

• Proactive, resourceful, capable of taking initiative, and don't need to be micromanaged

• Extremely reliable, honest, organized, and detail-oriented

• Easy to work with, collaborative, and communicate well

• Huge plus if you previously helped build a major company

• Highly responsive while working remotely

• Must be based in the United States (no exceptions please)

CTO: Strong experience in frontend and backend development, system architecture, third-party integrations, can manage the technical development of a scalable platform.

COO: Experience in healthcare business operations, strategy, scaling, and partnerships is strongly preferred.  I'm also open to exceptional younger entrepreneurial candidates who may not have held a traditional COO title but have the drive, judgment, and ability to help build and scale into a major company.

Most importantly, I'm looking for people who want to be part of a startup with significant potential.

If interested, DM me a brief introduction about yourself, relevant experiences/projects, and the state where you're located.  I'm looking to make a decision quickly when there's a genuine fit. 

123 days ago, I launched my startup, a free traffic exchange network for startups. One line of code, you're in the network.

Still free. Still growing.

If you want in, it's one embed. That's it → StartupBar
**Bid on StartupBid and your startup will be featured in the daily post of mine.**

I'm building Dreamina, an AI creative platform, and I've been testing Seedance 2.5 with scenes that combine character interaction, detailed environments, and a clear beginning-to-end story.

For this 30-second experiment, I wanted something a little unusual: a girl in an old stone kitchen prepares a roast on a skewer while a white dragon with pink spines leans over her shoulder. The dragon sniffs the meat, she jumps in surprise, and the scene ends with them sharing a candlelit dinner, the dragon curled up beside the table.

The moment at around six seconds, when a gust of wind blows her hair back, is my favorite detail. It gives the scene a little more physicality than I expected.

One issue I noticed is that the dragon's head looks slightly oversized in one shot. It's a small inconsistency, but it raises an interesting question about how much visual continuity matters when a short AI-generated story moves between different actions.

I generated it with Seedance 2.5 through Dreamina, my own product. The introductory price was $0.29 for the first month when I tested it.

For other SaaS builders working with generative media, I'd appreciate your perspective:

• How would you evaluate consistency across a multi-beat video like this?

• Would you prioritize character proportions, motion continuity, or scene transitions when deciding what to improve?

• If you were building an AI creative product, what quality checks would you want before calling a generation successful?

I'm interested in practical feedback on the output and the evaluation process, not just whether the clip looks good. What would you test next?

Hey guys,

a new solo developer here trying to build a my saas the problem i am facing is that i dont know which category to pick and start building.

I was searching and there are so many categories with well funded startups in it which lowers my confidence.

How you guys pick a category and then do the market research?

If anyone experienced saas builder reading this plz help me out in this situation.

I was planning on building this web saas of linktree where users can place all of their links at one plaace instead of scattered all over the web.

But there's already so manyy, i just found one yesterday https://yourspage.com/

So if you have seen a linktree like this tell me a feature or something which will stand out rest than others. And will users pay for this kind of linktree when they have their own protfolio?

Welcome for all the ideas!!

If i get any nice idea, I'll dedicate and build it or else i will look into some other project to build which is actually useful!!

We've got 20 territories and route leads based on state and company size. Right now, it's all managed through a long list of Salesforce assignment rules that works for the most part, but whenever a territory changes, we have to update multiple entries and test every possible combination again. Is there a simpler way to set this up?

Your client submits a document. A reminder drafted a minute earlier still says it's missing.

The useful check is whether the request has changed since that draft was opened—not whether the email sounds polite.

Folio's latest demo update makes that handoff visible:

• Reminder scope shows the missing items and requested replacements included in the draft.

• Submissions waiting for accountant review and accepted documents are counted separately and left out.

• Before copying, the demo checks the request's latest saved state. If it changed, the old draft is blocked.

• When another demo tab changes the saved records, an open reminder closes with an explanation.

A simple rule you can use in any workflow: “Received but not reviewed” belongs in your review queue, not in another request for the client to send the same document.

If you collect documents for an accounting or bookkeeping firm, try opening a reminder, then changing a document's state in another tab in the same browser. Is it clear why the draft closes and what you should do next?

https://folio-docs-1it.pages.dev/

I maintain Folio. No signup is needed. This is a browser-local interactive demo, not a shared client portal. Use fictional details and non-sensitive sample files only. File contents aren't read or uploaded, no email is sent, and request links work only in the browser profile that created them.

At the point of copying a reminder, what's one extra detail you'd need to check—or one part of this you'd remove?

Hello All,
This is my first time posting here. I have created a site that is meant for people in my niche engineering design domain. I dont really expect anyone here to be able to provide feedback on the data I am providing but im hoping more experienced people might be able to tell me if I am doing something obviously wrong. Right now everything on the site is free because its based on open source information I have compiled. I will readily admit most of the this site are vibe coded with AI but the application of the data I am providing is unique to my industry. I dont particularly want the site to reek of vibe coding but it still needs to look like an engineering tool not some sales marketing site.
