I have written in one of my comments here about how slow teh website is in one interacton

Then I scrolled even more in the website and the amount of lag, my my, I don't even know what to say but the amount of lag is something I have genuinely never witnessed in any website. This is like a new low. I really just want to archive this website to preserve how abysmally slow the website is and its aniations and everything. image literally loading 10% and everyhting.

Ship fast and break things is shying from what I am witnessing in here. Sfabt (ship fast and break things) is gonna use your service to talk to the agent which created this project to ask it personally to slow down

I can't view your website in 16 gigs of a computer... Weird where the world's progressing in this sense and how it got (YC funded?)

Quite frankly I am out of words for how slow the website is. Its really just that bad to be in its own league. Sorry to say.

The moat for SaaS is gone. I am 99% certain I could build to parity in a weekend using Cloudflare without the the pricing limitations. I am thinking it would be within the free tier of CF usage. I am not certain I have the bandwidth to communicate over delivery and plain text inspection concerns.

honestly, I have been thinking about it. But I feel like it would be a fun little side project if people actually try it out. (maybe you mention that you can build it)

So let's see how many people actually build it. Let's make it the new browser test instead and launch many open source solutions instead and see what's the best perhaps.

It would be a really great experiment imo.

Interesting take, but this feels like one of those tarpit ideas that YC discourages their portco to start attacking. Guaranteed this is going to attract a ton of abusers who are looking to use this for signing up to services, spamming or other nefarious purposes, which then blacklists the doman. This is an infinite whack-a-mole. do you guys have some ways of handling it?

We do have robust checks in place to catch spam and bad actors(reputation, SPF DKIM DMARC, etc.) but as with all tools there will be bad actors who come up with creative ways to scheme for nefarious purposes. We expect our infra and policies to evolve with usage, and one of our goals is to make agent driven email safer than the status quo, not just more scalable

But as of now you're just wide open for abuse? Okay

Resend uses SES since it's almost impossible to get private IP mail to hit the inbox through ProofPoint filters. Looks like you have no idea about any of this. You don't even have knowledge of email reputation, much less a plan. Have you heard of Senderscore? You will have all zeros. Saying "SPF DKIM DMARC" is wild - that's a checklist from 15 years ago.

We're going to collapse society with this style of thinking, particularly since it can now escape out into the realm of non-technical folks. Death of true understanding because everyone feels entitled to paying the lowest perceived monetary cost possible for everything in their lives.

underrated take :)

> The moat for SaaS is gone. What does this even mean? I could spend $1,000s on tokens asking an agent to build (some semblance of) Sentry, or New Relic, but why would I bother? I have real work to do in the near-term, and I'm happy to pay for services that help me do it.

It's a bit vague, but the idea is right. If your SaaS is built with AI, then any customer you have can also build it with AI, and whatever they build is going to be better suited to their needs and will run cheaper because they aren't paying your margin. AI skews the build vs buy curve massively, because it makes building so much easier

This completely ignores that a lot of products distill expertise into something manageable for the end user.

And that the actual act of these 3rd parties offering said products maintains not only the software, but the knowledge required to build it.

The moat around TV shows feels gone with TikTok/YT. I am 99% certain I could reach parity in a weekend by publishing content on public networks, without the old distribution or pricing constraints. I think it would all run on infrastructure that is effectively free to use. I am not certain I have the bandwidth to handle distribution, sustained attention, and moderation once the content starts flowing.

This is awesome

I thought cloudflares email product is only for receiving, not outbound ?

I was writing this comment and then asked AI model to find me a blog post and it looks like Cloudflare does support outbound now (I am seeing a send mail option) https://blog.cloudflare.com/email-service/ So yes it supports both and this feature was recently added (september 2025) & its still in private beta or something similar but yes now its possible. But I have still written parts of the comments where I had assu…

Cloudflare/SES works if you want raw email sending and receiving. If you want threading, parsing, storage, retrieval, logic, filtering, labeling, search -- you'll need to build it out yourself.

We're devs ourselves so ik the first thought is usually "how hard can it be?" in our validation, we thought it was hard enough to build a startup around :) these things are easier said than done, and no one in 2026 should be stitching together email workflows. especially not agents
