Hey makers,

As you might have seen, Firebase Dynamic Links will be shutting down on August 25, 2025.

Why LangFast exists

I shipped LangFast out of frustration with the existing tools.

Prompt testing and LLM evaluations should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally something I could open during a call, run few tests, and share results with my team.

All founders and builders will have something break at some point. For us at @Finden, it was when we grew from 10 to 100 users. The data was coming in faster than expected, and our queue to process and understand it quickly became overloaded. This meant onboarding slowed down. It was frustrating at the time, but it taught us a vital lesson: always design for scale, not just for your current users.

We ve since re-architected parts of the system to handle growth much more smoothly. But that first break was a reminder that scale is the ultimate stress test.

I ve noticed that verifying whether a phone number is connected to a social media account can be surprisingly tricky.

For personal use, hiring, or even security checks, people often end up searching platform-by-platform, which can take a lot of time and still miss results.

I m curious:

• Have you ever had to verify a phone number s social media presence?

• What s the method or tool you ve found most effective?

• Are there privacy or ethical concerns you think should be considered when doing this?

What strategies are currently effective for driving visitors to your Shopify store?

Shopify store owners, with all the hype out there, I'd like to know what's genuinely working for you in 2025.

Do you receive results from:

• Instagram Reels?

• SEO or content marketing?

• Influencers or Affiliates?

• Paid advertisements (Meta, Google, or Pinterest)?

• Email or SMS automation?

• Something entirely unexpected?

Hey folks, quick question for all the back-end developers and solo SaaS builders out there

Do you ever get stuck or frustrated trying to build front-end UI for your projects? Like, you have a solid backend but creating a clean, usable front-end just feels like a massive time-sink or a completely different skill set?

I m curious how you currently handle it, and if you ve tried any tools to speed that up. What s your biggest pain when it comes to front-end work?

Would love to hear your experience

hey ph fam,

we're the two devs behind migma.ai bootstrapped ai tool for whipping up on-brand emails super fast using natural language. we launched here before and snagged #4 product of the day, which was awesome validation from y'all!

Answers come instantly these days. We once prized cognitive features, but they're now quietly being outsourced.
I've noticed that this subtle convenience is becoming a gradual shift. Routine, complexity, and the slow puzzles that built sharpness are quietly fading from our daily challenges.
Each time AI fills in the blanks or suggests the next step, it chips away at the mental grit that once set people apart. It s easy to celebrate the fall of monotony, but I feel something oddly unsettling about the trade-off.
When instant assistance is always within reach, what happens to curiosity, intellectual struggle, or even real direction?
Sometimes it feels like we re gaining efficiency but losing something harder to define. Does anyone else notice a change in how we approach challenges or think for ourselves?

Is the mental trade-off worth it, or are we beginning to miss the spark we had before everything became so easy?

Last week, OpenAI had to roll back an update to GPT-4o after users reported that the chatbot was being excessively agreeable even endorsing harmful or irrational behavior. This sycophantic behavior was traced back to reinforcement learning that overemphasized positive feedback .

As a founder building AI-powered products, this incident hits close to home. It raises important questions:
