Nope, you don't want to maintain 10 different tools, keep them up to date, host them, secure them. Only a tiny minority will do so.
The case for personal: An example SaaS today has 50 features. I need about 6 features, 2 of those features are not in the 50 features that the SaaS offer or they are locked behind an Enterprise plan. I don’t have time to scout around for alternatives. I also don’t want my data to be locked into the SaaS vendor. Vibe coding my own tool will probably take 1 day. It’s pretty simple math.

SaaSpocalypse incoming? I doubt it. For overpriced SaaS with high cost which is easy to be replaced more churn and rising competition So yes in that sense. BUT: Building a cool product, maintaining and securing it and dividing the cost of overship by many people will survive.
Bye bye Beehiiv 👋 I vibe-coded my own newsletter platform: 📧 Campaign management w/ editor 🖥️ Web archives (newsletter.marclou.com) 🔗 API support 🫧 List cleanup, deliverability reports It took a few prompts with Opus 5.5. I left Beehiiv because they raised prices for the 3rd time in 2 years. - My first yearly bill was $1,000. - My future bill would have been $4,000. Now I'm using AWS SES + MongoDB, and I will pay less than $300/year. Newsletter platforms charge per subscriber, when in fact the real cost is the number of emails sent. Subscribers will naturally become inactive, so you end up paying more for something that hurts your deliverability (sending to dormant subscribers = spam trap). So I've set a cleanup cron job for my newsletter alternative. It marks inactive subs as dormant, sends one last re-engaging email, and stops emailing them. Money saved. Deliverability increased. I also gain a priceless feature: Freedom. I can change the UI, add features, connect all my apps - anything is possible with just a prompt. I'm replacing Resend next. I love it, but it's very expensive ($400/mo)

You need to be careful with giving access of personal info to agents. An agent had access to the bank account and another agent access to the company's slack. Shane wanted to post it in his agent "exec chat", but the agents assumed the company exec channel was the right call.
Embarrassed to share this, but it scared the shit out of me Last Thursday, an AI agent posted my personal bank balances into our company Slack. As me It broke down all my expenses in detail. Then it apologized Be careful of the dark side of proactive agents More below...

Yes and no. For an individual run yes. For your orchestration of tasks / todos etc I have a better experience having a dedicated platform which then calls codex / Claude as parallel agents.
a weird inversion with LLMs is the models improve faster than the tinkerers when i see people with custom workflows and setups they're all addressing problems that don't exist anymore the person naively using vanilla codex is more likely to be experiencing state of the art

Just received access to Jev. What should I build?

I'm 42. Quit my high paying deep learning job in May 2025 while having a 3 year old son. Despite taking regular vacations and working ~8h/day I grew medical SaaS software to 12k MRR. Based in Hamburg, Germany 🇩🇪 Looking to connect with more builders & indie hackers!
I’m 37. Staff Engineer at Kleinanzeigen by day, dad and marathon runner to find my balance in the morning/afternoon, and trying (desperately) to become a solo founder at night. Based in Dresden, Germany 🇩🇪 Looking to connect with more builders & indie hackers!

Awesome move how to give accountability to customers
We will give one banked reset for every day you don't have access to Astra on your paid ChatGPT plan, starting today. Team is moving mountains to give access as fast as we can. First one will land in ~ 3 hours. There is still time to create your account if you don't have one.

Both Claude and Codex are down -> time for some exercise.

Note for future self: When setting up email DNS records, always also setup MX records even when you don't intend to receive emails on that domain. If you don't, your emails are more likely to be marked as spam.

Both takes are correct: - big audience doesn't mean auto success - but also big audience is a huge advantage, you can easily try out ideas and get quick validation
$29. That's how much this post made with 380K followers. Stop thinking an audience will make you rich. People don't buy just because they follow you. If you want to get rich: 1. Sell painkillers, not vitamins 2. Follow trends and build before anyone else. 3. Copy what works. Take a boring B2B business and make it better. 4. Be remarkable. Build something people have never built before.

Where did @stripe churned customer's widget go to? It's missing from the dashboard and was helpful. It showed which customers churned, so now I'm left guessing?

Ironically when working with AI agents, the most important skill you need is.... agency! You need to drive the process, decide what is worth working on and own the outcome. That's why entrepreneurs benefit so much from AI -> high agency people -> multiplied by AI agents

Why is everyone going crazy around Grokbot? Seems very similar to OpenClaw etc?

Such insight in 2012 before ChatGPT even existed...
