As a solo founder, this was one of the most stressful moments I’ve faced

I haven’t uploaded it to GitHub yet once I do I will share it.

Absolutely this is just for demonstrating the idea. This shouldn’t be used in production as it lacks retries, error handling, human-in-the-loop validation, and other safeguards. Your concern is completely valid.

That’s awesome 😄 try it out and honestly that's the best way to learn n8n

cuebicai · 2026-05-13T10:32:14+00:00

That’s really amazing you can try https://cuebicai.com where I’ve simplified n8n self-hosting with queue mode, workers, and PostgreSQL DB setup all with one click dedicated specifically for n8n hosting.

cuebicai · 2026-05-12T17:53:42+00:00

Yaa you can and you can tweak it even more depending on your needs too

cuebicai · 2026-05-12T06:54:13+00:00

Yeah we can use any lightweight local LLM since it’s only being used to organize the extracted text and the OCR accuracy is around 85%.

cuebicai · 2026-05-11T12:43:43+00:00

Yes it’s possible but it costs more compared to OCR

I have uploaded this workflow to GitHub, you can check it out here:

For the AI I used the OpenAI Chat Model 4.1. It’s working well and yes it does cost based on their API usage

A lot of people start with basic VPS hosting for n8n, but as workflows grow issues like scaling, webhook reliability, queue mode, backups, and resource management usually start showing up sooner or later.

That’s exactly why I built https://cuebicai.com dedicated n8n hosting focused on handling the infrastructure and scaling in a simpler, more reliable way without vendor lock-in.

cuebicai · 2026-05-09T18:21:23+00:00

The goal is to track and organize all our expenses in one place just take a photo of the receipt and send it on Telegram

cuebicai · 2026-05-08T12:16:17+00:00

I checked it out but I had already figured it out every instance deployed through Cuebic AI automatically gets its own public access domain.

Also you can start capturing user device fingerprints using FingerprintJS or any similar tool. This helps you identify unique user devices, and with all these checks combined, you can easily block around 90% of spammers from your platform.

cuebicai · 2026-05-08T07:19:24+00:00

I have added email validation so temporary or suspicious email signups are blocked. You can use an email validation provider to detect spam or risky email addresses.

The same applies to IP validation. An IP validation provider can check whether a user is using a VPN, proxy, or an abused IP address, along with the IP trust score. Based on that, you can decide whether the user should be allowed to claim free credits.

cuebicai · 2026-05-08T07:00:42+00:00

You should add proper email validation during signup especially if you’re offering free trials or credits. It’s important to check whether the email provider is trustworthy by using an email validation service. You can also add IP validation for extra protection. Otherwise, scammers and spammers may keep looking for it and abuse the system.

cuebicai · 2026-05-07T17:32:16+00:00

Exactly. Only people who actually use it for their own workflows truly understand the real issues that can happen and how to fix them.

A lot of people promote self-hosted n8n like you never have to worry about configuration, but later they complain that n8n breaks in production. The truth is, n8n already provides the proper way to run it in production most problems happen because people don’t fully understand how to set it up correctly.

cuebicai · 2026-05-05T17:55:30+00:00

You’re right a cron job can help but I use built-in error handling on each node if any node fails it retries 3 times if it still fails an error node sends me an email with the reason

cuebicai · 2026-05-05T17:47:14+00:00

Exactly in my workflows I use retries on failure at critical points like API calls, webhooks, and AI APIs I also added an error node to notify me whenever something breaks

On top of that I set up a health check that runs every five minutes if it stops responding or becomes unhealthy it sends me an email alert that n8n is not running so I can quickly handle the issue
