Hi everyone,
I’d like to share my experience as both an instructor and developer using Replit right now, a platform I once considered one of the most powerful and promising tools in the world of vibe coding.
I started exploring vibe coding around October 2024, experimenting with different languages and environments. That’s when I discovered Replit, and by January 2025 I had subscribed to the platform to use it in a more professional and committed way.
For several months, the experience was truly excellent. Replit gave me speed, flexibility, and power. Each update brought new features—some very useful, some less relevant—but I was always able to select what worked for me and move forward with my projects.
As an educator, I recommended Replit to many of my students. A good number of them signed up, started building real-world applications, and some even earned money from their work. One student in particular built a full project and successfully sold it for $250,000. This was someone with no technical background, empowered entirely through Replit. That speaks volumes about what the platform used to enable.
Personally, I developed complex, production-level projects with Replit, including:
-
Business management systems for boat rental companies
-
Custom CRM solutions
-
A trading bot for MemeCoins, which featured:
-
Real-time chart monitoring
-
Direct integration with a Solana wallet
-
Three SDKs working together via their respective endpoints and URLs
-
All of that was made possible thanks to Agent 2, which gave me the tools and reliability I needed to build confidently and efficiently.
However, this summer, things have taken a serious downturn.
Prices have increased significantly. Development processes now take far longer. Even after paying more, there’s no guarantee things will work as expected. The cost of prompts and compute usage has become very high, even without enabling additional tools like Boosts or external agents.
Many of my students (around 50 active users) have started questioning whether it makes sense to continue on Replit. It’s simply not competitive anymore—neither in terms of price nor performance.
And this brings me to Agent 3.
In my opinion, Agent 3 has been the worst integration Replit has released during my time on the platform. It’s slow, unhelpful, expensive, and inefficient. It doesn’t solve real problems, it consumes a lot of resources, and rarely delivers useful output, it has been a complete failure.
To be honest, I now feel hesitant and even afraid to start new projects on Replit. I don’t trust that I’ll be able to complete them like I could before. I don’t believe Agent 3 can achieve anything close to what I was able to build with Agent 2—and that’s deeply concerning for someone who has fully committed to this platform.
I’m sharing this feedback not to criticize for the sake of it, but because I genuinely believe in the potential of Replit and in the future of vibe coding. I’ve been one of the people actively using and promoting this platform in real educational and professional settings. But right now, the direction Replit is taking is pushing us away, not bringing us closer.
Thanks for reading—and I sincerely hope this feedback is taken into account.
