Introduction
What Technologies Are Developers Actually Using and How They’re Changing Year Over Year.
In Part 1, we talked about the trust gap in AI, the cautious optimism of devs, and the rise of productivity-first workflows. But now let’s flip to the technologies and frameworks.
If you still haven’t checked out part 1 of the Developer Survey on Stack Overflow, check it here:
Let’s unpack what 49,000+ developers had to say about Stack Overflow Developer Survey 2025’s most popular programming languages, web frameworks, databases, and languages, what’s gaining momentum, what’s losing the spark, and more.
Stack overflow developer survey 2025 most popular programming languages
One of the most dramatic shifts in this year’s Stack Overflow Technologies Survey 2025 was that Python saw a +7% increase in usage YoY.
Why? Because it’s not just a scripting tool anymore, it’s the language of AI, backend APIs, and data pipelines. Paired with FastAPI’s growth (more on that below), Python has gone from popular to essential.
Languages on the Rise (YoY % Increase vs 2024)
| Language | 2024 → 2025 | Key Driver |
|---|---|---|
| Python | +7% | AI, FastAPI, ML workflows |
| Rust | +3% | Performance, safety in production |
| TypeScript | +2.5% | Better type safety, React/Next.js |
| Go | +2% | Scalable APIs and concurrency |
Languages in Decline (YoY % Decreases vs 2024)
| Language | Change | Reason |
|---|---|---|
| PHP | -3% | Legacy use only |
| Ruby | -2.5% | Losing ground to modern backends |
| Visual Basic | -2% | Aging tech stack |
| Perl | -1.8% | Low modern adoption |
As per the Stack Overflow Developer Survey 2025, the most popular technologies, JavaScript remains the top-used language at 66% in the Stack Overflow Technology Survey, but most of the buzz is happening around Python, Rust, and TypeScript — languages that power next-gen stacks.
AI’s Influence on Language Choices
The StackOverflow survey 25 showed that developers using AI tools prefer modern, fast, and flexible languages, like Python, Rust, Go, and TypeScript. Legacy languages are still used, but are rarely selected as “want to learn next.”
Stack Overflow Developer Survey 2025 Most Popular Databases PostgreSQL Still #1
Top 5 Most Used Databases – 2025
| Database | Usage % | YoY Trend |
|---|---|---|
| PostgreSQL | 55.6% | ↔️ Steady |
| MySQL | 40.5% | 🔽 Slight decline |
| SQLite | 37.5% | 🔼 Slight gain (used in mobile/dev tools) |
| SQL Server | 30.1% | 🔽 Gradual decline |
| Redis | 28% | 🔥 +8% YoY |
As per the Stack Overflow Developer Survey 2025: most popular databases the biggest story here is Redis, jumping +8% in usage, showing how caching, in-memory data stores, and microservices architecture are becoming the norm.
Developers now expect high-speed, low-latency data solutions, and Redis delivers.
Stack Overflow Developer Survey 2025 Most popular web frameworks
In last year’s Stack Overflow Developer Survey 2025, Most Popular Web Frameworks: Node.js, React, and Express led the charge. They still dominate. But 2025 is all about performance and flexibility, and that’s why:
- FastAPI jumped +5%
- Next.js continues to climb (up 3% YoY)
- jQuery, AngularJS, and older PHP frameworks are fading
Stack Overflow Developer Survey 2025: Most Popular Web Frameworks! FastAPI and Next.js Are the Stars of 2025!
| Framework | Usage % | Notable Shift |
|---|---|---|
| PostgreSQL | 48.7% | ↔️ Stable |
| React | 44.7% | ↔️ Holding strong |
| Next.js | 20.8% | 🔼 Replacing Create React App |
| FastAPI | 14.8% | 🔥 Huge surge |
| Flask | 14.4% | 🔽 Losing ground to FastAPI |
| Vue.js | 17.6% | 🔼 Slight gain |
| AngularJS | 7.2% | 🔽 Continues to drop |
FastAPI’s rise is tied directly to Python’s success.
What does This Mean for Your Stack?
Here’s what we’re seeing across thousands of devs globally as per the Stack Overflow Technology Survey:
- Modern, high-performance languages and frameworks are winning
- Python is the most versatile language in the stack right now
- Redis is becoming core to high-speed architecture
- FastAPI, Next.js, and Supabase are no longer niche tools
If you’re planning your dev roadmap for Q4 or hiring for your next big build, these aren’t just trends, they’re market signals.
