<p>what do you think it should be called? for ~$15 optional one time bucks people get 24/7 access to the entire engineering team, me, prioritized feature dev, and can earn monthly payouts from our Creator Fund. we don’t charge a subscription, obviously i’m partial but this model has serves us well. and most of the developer edition fee goes right back to the community via bounties, perks, etc.</p>

<p>you can import ~700 plugins from core to Terminus (Hanami build) or the Laravel build in 1 click. maybe you came on board before that was a reality. we and the community have been rapidly developing multiple self hosted servers with all kinds of features and in different frameworks for comfort. in no marketing materials have we ever claimed that OSS clients were the same as the main web app. in fact that’s why we offer a BYOD license for the web app only. we’ve invested hundreds of thousands into open source so that people can get the TRMNL experience without paying us a penny.</p>

<p>OP's Timeframe looks rad, but yes on the pricy side. check out trmnl .com for smaller / less expensive options and self hosted options. (disclaimer: i'm on the team)</p>

<p>oh interesting. i suppose we (or you) could be a plugin that parses epub/* formats and thus, a button click on device would fetch the next screen. double-click can already be set to go in reverse. but the full feedback loop takes a few seconds, not instant like an e-reader.</p>

<p>ok back up - you claimed we used fake data. obviously you are referring to "John bought X, Y mins ago" notifications. the actual product.<p>for our homepage counter, this is not customers. this is notification count. with thousands of connected websites, each showing multiple notifications per page load, we quick racked up billions of notifications shown.<p>running `select count(*) from events` on every landing page load is untenable. instead, every N period we'd check on our avg daily notification count, then update the landing page JS to give users a sense of scale. this number was perpetually under-reporting our actual metrics.<p>for metrics that actually matter, like signups, customers etc, we created an Open API and read from those metrics on various landing pages:
<a href="https://fomo.com/open" rel="nofollow">https://fomo.com/open</a>
<a href="https://docs.fomo.com/reference/fomo-open" rel="nofollow">https://docs.fomo.com/reference/fomo-open</a><p>and for the core product notifications, "John bought X, Y mins ago" we only allowed data from native integrations. if we saw someone pinging webhooks to us with fake data, we deleted their account. if someone asked for a CSV upload feature, we deleted their account. i cannot say the same for our competitors, who welcomed these use cases with open arms.<p>bottom line - you're a hater. you don't like Fomo (fine), so you're trying to sabotage the sale of another, completely unrelated product. think about where this bitterness comes from and do better next time.</p>

<p>jumping in to defend myself (thanks f5bot). you are not a serious person.<p>1. i'm very proud of Fomo. for 6 years we fought against fake data. i said "no" to many lucrative opportunities that were not ethical. our vision was "to given entrepreneurs the credit they deserve," and our mission was "to help consumers make better buying decisions online." your comment is libelous. [1, 2]<p>2. as of yesterday, all 11 of my courses are free. i've helped over 10,000 people learn to code and learn to sell. [3]<p>3. on the side i do a bit of pen-testing. i help stop* scammers, and i help non technical folks protect their brand. that's why Bubble added me to their home pages and dozens of cash bounties have been sent my way.
