When I first started working with PHP, I never imagined that I would spend much time thinking about languages like Rust.

PHP was enough.

Laravel made backend development even easier.

I could build:

• APIs
• ERP systems
• CRMs
• SaaS products
• Payment integrations
• Queue workers
• Admin panels

and move very quickly.

So naturally, one question comes to mind:

Why should a PHP developer care about Rust?

I don't think the answer is:

"PHP is becoming useless."

It isn't.

The better answer is:

The role of backend development is changing, and Rust is becoming important in the parts of software where performance, safety and low-level control matter.

That is why I think understanding Rust is useful even if I continue building most business applications with Laravel.

Rust is not a new language anymore

Rust has been around for years.

But its position in the developer ecosystem has changed significantly.

Stack Overflow's 2025 Developer Survey again ranked Rust as the most admired programming language, with 72.4% of Rust users saying they want to continue using it. The survey also noted Rust's growing usage and the importance of Cargo in its ecosystem.

This matters because there are many programming languages that developers like.

But admiration alone does not make a language important.

What makes Rust interesting is where it is being used.

Rust is increasingly visible in:

• Infrastructure
• Cloud tooling
• Developer tools
• Networking
• Databases
• Operating-system components
• Performance-sensitive applications
• WebAssembly
• Security-sensitive software

That is a very different position from simply being another programming language people experiment with.

Why did Rust become so popular?

For me, three words explain a lot of it:

Performance.

Memory safety.

Control.

Traditional low-level languages such as C and C++ provide enormous control and performance.

But that control also makes certain classes of programming errors easier to introduce.

Rust tries to give developers low-level performance while enforcing strong guarantees through its type system and ownership model.

That is the part that attracted a lot of attention.

Rust thinks differently about memory

This is probably the biggest conceptual difference for a PHP developer.

In PHP, developers normally don't think deeply about memory ownership.

We write:

$user = User::find($id);

and continue building the application.

PHP handles memory management for us.

Rust is different.

The language makes ownership and borrowing central concepts.

At first, this feels difficult.

A developer coming from PHP or JavaScript may look at Rust code and think:

"Why is the compiler arguing with me about this?"

But that strictness is intentional.

The compiler is trying to detect problems before the program runs.

Rust's compiler is part of the programming model

This is something I find interesting.

In many languages, developers think:

"I'll write the code and fix runtime bugs later."

Rust tries to move more problems into compile time.

For example, memory-related errors that might become production crashes in other systems can often be caught during compilation.

That creates a different development experience.

The compiler becomes more like a reviewer that refuses to let certain classes of mistakes through.

At first that can feel frustrating.

Later, many developers find it useful.

PHP gives us speed of development

This is one reason I still like PHP and Laravel.

I can build a business feature quickly.

For example:

Customer
↓
Controller
↓
Service
↓
Model
↓
Database

Laravel gives me:

• Routing
• Authentication
• Validation
• Queues
• Jobs
• Events
• Mail
• Notifications
• ORM
• Migrations
• Cache

This makes PHP extremely productive for business applications.

Rust is not trying to solve the exact same problem.

That is why I don't look at:

Laravel vs Rust

as a simple competition.

I see different strengths.

Laravel is excellent for business logic

Suppose I need to build:

ERP
CRM
Booking
Inventory
Invoice
Subscription
Admin Panel

I don't necessarily need the lowest possible system-level overhead.

I need:

• Fast development
• Good database support
• Authentication
• Validation
• Forms
• APIs
• Queues
• Integrations
• Maintainability

Laravel is very strong here.

Replacing all of this with Rust simply because Rust is faster would not automatically create a better product.

We would probably make development slower.

So where does Rust make sense?

This is the interesting part.

Suppose we have a Laravel SaaS platform.

Most of the application is:

Laravel
MySQL/PostgreSQL
Redis
React

Everything is working fine.

But we have one workload that consumes a huge amount of CPU.

Maybe:

• File processing
• Image processing
• Video processing
• Data compression
• Large-scale parsing
• Network processing
• Encryption
• Search
• High-volume event processing

Do we need to rewrite the entire application?

No.

We can isolate the performance-sensitive component.

This is where Rust becomes interesting.

PHP does not have to do everything

I think this is an important architectural mindset.

A modern system does not need to be written in one programming language.

For example:

Laravel
   |
   +---- REST API
   |
   +---- MySQL
   |
   +---- Redis
   |
   +---- Rust Service

Laravel handles the business application.

Rust handles one specialized workload.

This is much more realistic than:

"We need to rewrite our Laravel application in Rust."

Think about image processing

Imagine a SaaS application that processes millions of images.

Laravel can absolutely handle the business workflow:

Upload image
↓
Create job
↓
Store metadata
↓
Send processing request
↓
Update status

But the actual heavy processing might happen somewhere else.

For example:

Laravel
    ↓
Queue
    ↓
Rust Worker
    ↓
Image Processing
    ↓
Object Storage

Now we get the advantages of both technologies.

PHP remains productive.

Rust handles the computationally heavy workload.

The same idea applies to data processing

Suppose an ERP system generates huge exports.

A normal request should not sit there for five minutes.

Laravel can create a job.

Then:

Laravel Queue
      ↓
Data Processor
      ↓
CSV / JSON
      ↓
Object Storage

That processor could be written in a language selected for its workload.

Again, we don't need to rewrite the entire application.

Rust is also becoming important for developer tools

This part is very interesting.

Rust is not only being used for backend applications.

It has become increasingly common in tools developers use every day.

Stack Overflow's 2025 survey highlighted Cargo as the most admired cloud development and infrastructure tool, reflecting how strong Rust's development ecosystem has become.

We are also seeing more developer tooling written in Rust because it can deliver fast startup times and good performance.

This matters even to developers who never write Rust.

We may still use Rust-built tools from the command line.

That means understanding Rust's ecosystem gives us a better understanding of where modern developer tooling is going.

Rust and WebAssembly

Another reason I pay attention to Rust is WebAssembly.

WebAssembly allows code compiled into WASM to run in environments such as the browser and other runtimes.

This creates an interesting architecture.

Imagine our application uses:

React
+
TypeScript

but one feature is computationally expensive.

Instead of doing everything in JavaScript, certain workloads can potentially run through WebAssembly.

Rust is one of the languages commonly used for this type of work.

Again, I am not saying:

"Replace JavaScript with Rust."

It is more about adding Rust where the workload justifies it.

Rust is also interesting for security

This is another reason the language is getting attention.

Memory safety has become a serious topic in modern software security.

Languages with stronger memory-safety guarantees can reduce certain classes of vulnerabilities.

This does not mean Rust code is automatically secure.

Of course it isn't.

A developer can still write:

• Broken authorization
• Bad business logic
• Insecure cryptography
• Vulnerable APIs
• Unsafe dependencies

But eliminating entire categories of memory errors can still be valuable.

That is particularly interesting in infrastructure and security-sensitive software.

Why this matters for SaaS developers

At first glance, Rust may seem unrelated to a normal SaaS application.

But SaaS architecture is becoming more distributed.

We now have:

Frontend
API
Workers
Queues
Search
Storage
Analytics
Notifications
Background Processing
Integrations

Different parts have different requirements.

Some want developer productivity.

Some want low latency.

Some want throughput.

Some want strong isolation.

Some want low resource consumption.

This naturally leads to polyglot architectures.

I would not write an ERP completely in Rust

This is where I have a strong opinion.

If I need to build:

Customer Management
Invoice Management
User Management
Subscriptions
Admin Panel
Reports

I would still be very comfortable using Laravel.

The development speed is extremely valuable.

I don't want to spend weeks implementing infrastructure that Laravel already gives me.

The language should match the problem.

Not our ego.

Don't choose technology based on benchmark charts

This is another trap.

You will find benchmarks where Rust is much faster than PHP.

That may be true for specific workloads.

But an application is not a benchmark.

Suppose Rust processes something in:

10 ms

and PHP processes the same workload in:

20 ms

But the database query takes:

200 ms

and an external API takes:

800 ms

Then rewriting the 10 ms operation in Rust isn't going to transform the application's user experience.

This is why I always prefer:

Measure first.

Then optimize.

Rust can also introduce complexity

We should be honest about this.

Rust has a steeper learning curve.

Developers need to understand:

• Ownership
• Borrowing
• Lifetimes
• Traits
• Enums
• Pattern matching
• Result
• Option
• Async programming
• Cargo
• Crates

For somebody coming from PHP, this is a significant mental shift.

So learning Rust is an investment.

The question is whether that investment is valuable for your career and projects.

For many backend developers, I believe it is.

You don't need to become a Rust expert

This is something I want to emphasize.

I don't think every Laravel developer needs to build a complete Rust application tomorrow.

Start by understanding the ecosystem.

Learn:

Cargo
Crates
Ownership
Structs
Enums
Traits
Result
Option
Basic async

Then build something small.

Maybe:

CLI tool

or:

File processor

or:

Small API

or:

High-performance worker

That is enough to understand how Rust feels.

Rust can also change how you think about programming

This is probably the biggest long-term value.

Even if I return to PHP after learning Rust, I may think differently about:

• Data ownership
• Mutability
• Error handling
• Memory
• Concurrency
• API boundaries
• Explicit types
• Failure modes

Learning another programming model can make us better at the language we already use.

That has happened to me with different technologies over the years.

Sometimes the biggest benefit of learning a new language is not using it in production.

It is bringing better ideas back to your main stack.

Rust vs Go is a more interesting comparison

If somebody tells me:

"I need a fast backend language."

I would not immediately answer:

"Use Rust."

I would also look at Go.

Go has:

• Simple syntax
• Easy deployment
• Good concurrency
• Strong cloud adoption
• Fast compilation
• A relatively small learning curve

Rust gives more control and stronger compile-time guarantees.

Go often gives faster onboarding.

Both are valuable.

Again:

The problem decides the language.

PHP is also evolving

Another important point.

I don't think the rise of Rust means languages like PHP are standing still.

PHP has improved significantly over the years.

Modern PHP has:

• Better typing
• Better performance
• Better error handling
• Modern language features
• Stronger tooling

Laravel also keeps evolving.

So I don't see this as:

Old PHP
↓
New Rust

I see:

Modern backend ecosystem
        |
   Multiple tools
        |
PHP + Rust + Go + JavaScript + others

Different tools can work together.

For a Laravel developer, learning system design may be more valuable

This is another important point.

I would not spend six months learning Rust while ignoring:

• Database optimization
• Caching
• Queues
• API design
• Security
• Distributed systems
• Monitoring
• Deployment

Those skills are still directly useful in Laravel.

Rust should be another tool in the toolbox.

Not a replacement for good engineering fundamentals.

My practical approach

Suppose I am building a SaaS product today.

I would start with Laravel.

Then I would measure the application.

If one part becomes a real bottleneck, I would ask:

Can I fix it with:

• Better SQL?
• Better indexes?
• Caching?
• Redis?
• Queue architecture?
• Horizontal scaling?
• Better algorithms?

Only after those questions would I consider rewriting that component in another language.

And if the workload genuinely needs it, Rust could be one of the choices.

That is a much healthier engineering process.

Rust is a signal about where software is going

This is what interests me most.

The growth of Rust is not only about one programming language.

It reflects a larger trend toward:

• Performance
• Memory safety
• Efficient infrastructure
• Better developer tooling
• Native applications
• Cloud infrastructure
• High-performance services

The 2025 Stack Overflow survey also shows Rust continuing to stand out both for developer admiration and growing usage, while Cargo remains highly regarded among cloud-development tools.

That tells me Rust is worth understanding even if it is not my primary language.

My final view

I don't think PHP developers need to abandon PHP because Rust is popular.

And I definitely don't think every Laravel project should be rewritten in Rust.

For business software, Laravel is still an extremely productive choice.

But I also don't want to ignore where the industry is going.

Rust is becoming important in infrastructure, developer tooling, performance-sensitive systems and security-sensitive software.

So for me, the right mindset is:

Laravel for productivity.

Rust where performance, control or safety justify it.

And sometimes:

Laravel + Rust together.

That last option is probably the one I find most interesting.

Because modern software development is not about finding one language that can do everything.

It is about understanding different tools well enough to use the right one for the right problem.

That is why I think every serious backend developer should at least understand why Rust is growing, even if they never replace their main stack with it.
