What a frontend developer does
A frontend developer builds the part of a website or app that users actually touch: layouts, buttons, forms, animations, and everything that has to work on a five-year-old phone as well as a new laptop. They take a design and make it real, fast, and clickable.
The line to understand: frontend developers build what you see; a backend developer builds what you don’t — databases, logins, the machinery behind the form. Most polished websites need both, which is why frontend devs are often hired into existing teams or paired with a backend counterpart rather than building alone.
What it costs
Independent frontend developers typically charge $50–$160 per hour. Juniors and developers in lower-cost regions sit at the bottom; specialists in a specific framework with years of shipped work sit at the top. What moves the rate:
- Framework depth — a developer who lives in the tool your project uses works faster, and faster at a higher rate often costs less overall.
- Design fidelity — pixel-perfect builds from detailed design files take more hours than “make it look decent.”
- Interactivity — static pages are cheap; live filtering, dashboards, and animation are where hours accumulate.
Rate context and typical project totals are in our frontend developer cost guide. If you’re unsure whether to buy hours or a fixed price, read hourly vs fixed price first — for open-ended frontend work, hourly with a weekly cap is usually the fair structure for both sides.
How to evaluate one
You can’t read their code, so judge the things you can. Open three sites they built on your own phone. Resize the browser window and watch what breaks. Click the forms. Slow sites, broken layouts, and dead buttons are the frontend equivalent of typos in a writer’s portfolio.
Then judge communication. A professional asks about your users and devices before quoting, explains trade-offs without jargon, and gives estimates in ranges. An amateur says “easy, two days” to everything. Frontend work is famously 80% done at the halfway mark — you want someone who plans for the last 20%.
What to prepare before you start
Frontend developers build from designs. Show up with finished design files and you’ll pay for building; show up with a sketch and you’ll pay them to design by trial and error at developer rates, which is the expensive way to get mediocre design. If the look matters, hire a designer first or find a developer who honestly does both — and check their portfolio proves it.
Also decide who’s answering questions daily. Frontend work generates constant small decisions (“what should this button do when it fails?”), and a responsive client is the difference between a two-week job and a six-week one.
Questions to ask before you hire
- Can you show me something you built and walk me through what was hard about it?
- How do you make sure the site works on phones and older browsers, not just your laptop?
- What framework would you use for my project, and why that one?
- How will you hand off the code so another developer could pick it up later?
- Do you test what you build, or does that fall to me?
Red flags
- Their portfolio sites look fine on desktop and fall apart on a phone. Check on yours before the call.
- They pick the framework before hearing the problem — that's a hammer looking for nails.
- No answer for browser or device testing beyond "it works for me."
- They can't explain a technical decision in plain English. You'll be living with that communication style.
