Easily compare the costs of newsletter platforms
I've been writing on Substack for the last year, and from the beginning I've been aware that I might want to migrate to a different platform at some point. I've been looking into the various alternatives to Substack for a while, and always found it difficult to compare costs across the different platforms. There's just too many variables that factor into the cost, and each platform has a slightly different pricing scheme. I've also been looking for the chance to try Streamlit, a Python library for making dashboards. Getting started with Streamlit was even easier than I imagined, so I ended…

In plain words
This tool helps newsletter creators compare pricing across five platforms—Ghost Pro, Buttondown, beehiiv, Substack, and ConvertKit—by inputting subscriber counts, paid subscription percentages, and expected revenue. Built with Streamlit, it addresses the difficulty of evaluating different pricing schemes across platforms with varying cost structures. It is designed for writers considering migrating from their current newsletter platform or choosing between services.

- BABuilt an email marketing platform after paying $230/month2025 · fertit.com · ▲44
Spent the last month building Fertit - basically a newsletter manager but you bring your own SMTP and skip the DevOps nightmare. All the features (subscriber management, admin dashboard, custom preferences) without the infrastructure markup. The math that broke me: Mailchimp: $230/month for 15k contacts My solution: $10/month infrastructure + $10 SendGrid = unlimited What I learned: The "enterprise" features are mostly database operations with SMTP APIs. But the 3 weeks of Go/PostgreSQL/Redis setup explains why people just pay ConvertKit $300/month. Here's the thing:…
Subwise2025 · usesubwise.com · ▲19Hey HN, I built Subwise to solve a personal pain point: keeping track of all the subscriptions I’ve signed up for — from SaaS tools to streaming services. What it does Automatically detects subscriptions from checkout pages using a browser extension Syncs with a web dashboard that categorizes, tracks, and reminds you of recurring charges Gives spending analytics, trends, and cost-saving insights Supports multi-currency tracking (USD, PHP, SGD) with live conversion Why I built it Too many tools focus just on logging expenses. I wanted something that works more like a smart assistant —…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
