Browser Game Dev Portfolio Tips That Land Jobs

A browser game developer’s portfolio is the single most important asset in landing a job, a contract, or an audience. The technical interview matters; the portfolio matters more. These browser game dev portfolio tips come from what hiring managers and indie publishers actually look at, in the order they look at it. The advice is practical: scope discipline, video demos, GitHub hygiene, and the narrative that makes your projects look intentional rather than scattershot.

1. Ship three polished games before adding more

The single most common portfolio mistake is too many projects with too little polish. A portfolio of fifteen jam games at varying levels of completion looks unfocused. Three games that are clearly finished, clearly playable, and clearly presentable look professional.

“Polished” means: the game starts cleanly, the controls work, there’s a real ending or game over state, no obvious bugs in the first five minutes of play, and the page presenting the game looks like effort went into it. You don’t need AAA art; you need the basics done right.

If you have ten jam games and three are clearly your best work, archive or de-emphasize the other seven. Hiring managers scroll. Make the first three things they see your best.

2. Project diversity

Variety across your projects signals range. The portfolio that’s all clones of the same genre tells a narrow story. A portfolio with one platformer, one puzzle game, one multiplayer prototype, and one narrative experience tells a wider one.

Concrete diversity to aim for:

• Genre variety: Action, puzzle, narrative, simulation. Pick three.
• Mechanic diversity: Real-time, turn-based, asynchronous. Show you’ve thought about more than one pacing.
• Multiplayer or networked work: Even a small WebSocket prototype demonstrates skills most solo devs lack.
• One technical deep-dive: A custom shader, a physics implementation, an AI behavior tree — something that’s not just gameplay.

Diversity is not the same as scope. Each project can be small. A small turn-based game, a small platformer, and a small puzzle game together tell a stronger story than one large project in one genre.

3. The 30-second video demo is non-negotiable

Most reviewers won’t play your game. They’ll watch the first 30 seconds of a video and decide whether to keep looking. If your portfolio doesn’t have a gameplay video — or worse, only has a “play in browser” link that takes a minute to load — most of your audience will move on.

The good 30-second video shows:

• The core gameplay loop in the first five seconds.
• Multiple game states (menus, levels, game over) so reviewers see the game is finished.
• The actual feel of playing — not a static slideshow of screenshots.
• Sound design if the game has any.

Tools for capture: OBS Studio (free), the built-in macOS Screen Recording, or browser-based screen capture for the lowest-friction option. Edit in DaVinci Resolve (free) or Final Cut for video editing.

Host on YouTube unlisted, Twitter/X video upload, or embedded MP4 on the itch page. Whatever works in your portfolio context.

4. Scope discipline as a signal

Hiring managers look for scope discipline because it’s the rarest indie game development skill. A portfolio of small, finished games signals discipline. A portfolio of ambitious half-finished games signals the opposite.

The implicit promise: “I finish things.” That’s the whole point. The games can be small. They have to be done.

If you have an ambitious project that’s not done, don’t put it in the portfolio yet. Put the small finished things first. The ambitious project becomes a portfolio piece when it’s actually finished.

5. GitHub READMEs that signal you can collaborate

If your code is open source on GitHub — which it should be for at least one or two portfolio projects — the README is the second thing a reviewer looks at after the gameplay video. A good README has:

• A one-paragraph description of what the game is.
• A screenshot or animated GIF at the top.
• “How to run” instructions that actually work on a clean clone.
• “How it works” — a brief technical overview.
• A note on what you learned or what was hard.

The README is the audition for whether you can write documentation, communicate clearly, and care about the person reading your code. Some hiring managers admit to reading READMEs more carefully than the code itself. The README is your interview.

6. The “what I learned” narrative

Each project page benefits from a short reflection: “What I learned building this.” This turns the project from an artifact into evidence of growth. Examples:

• “This was my first multiplayer project. I learned that latency compensation is harder than the tutorials suggest.”
• “The original scope had ten levels. I cut to three to ship. Scope discipline is a learned skill.”
• “I implemented A* pathfinding for the AI. Watching the pathfinder make obviously suboptimal decisions taught me more than reading about it.”

This is the part of the portfolio that humans engage with. The code is the credential; the narrative is the conversation.

7. The hosting matters

Where you host your portfolio affects how reviewers experience it:

• itch.io profile: The default. Aggregates your games, has built-in browser-play support, has a community.
• Personal site: More control, more curation, but more maintenance. A simple HTML site is fine.
• GitHub Pages: Free, version-controlled, and signals you know how to deploy.

You don’t need all three. Pick one as the canonical home and link to the others. The worst portfolio is the one spread across three half-maintained surfaces.

8. Show one non-game technical project

Browser game development is web development with extra constraints. A portfolio with at least one non-game web project — a tool, a generator, a visualization — signals you can work outside the gameplay loop. Examples:

• A level editor for your own game.
• A sprite-sheet packer or shader playground.
• A data visualization of your game’s analytics.
• A small library you published to npm.

This isn’t required, but it differentiates you. Most game dev portfolios are 100% games. One non-game project signals broader thinking.

9. The first game on the page should be your best

Order matters. Reviewers scroll top to bottom and lose patience as they go. The first game on your portfolio is the one most reviewers will engage with the longest. The fifth game is barely going to get looked at.

Put your best work first. Update the order when your best work changes. This is hygiene that most portfolios skip — most portfolios are chronological, which means the newest work is at the top whether or not it’s the strongest.

10. Maintain it

A portfolio that hasn’t been updated in two years signals you’ve stopped shipping. Even a small new project added every few months keeps the timeline alive. The active portfolio looks healthier than the dormant one even if the dormant one has objectively stronger work.

Inspiration from the canon

For inspiration on what minimal, focused, well-presented game work looks like, the source code for the Chrome Dino game is publicly available — about 600 lines of JavaScript that became one of the most-played games in history. The lesson isn’t the code itself; it’s the scope. The game does one thing, does it well, and has been seen by billions. Most indie portfolios would benefit from games that focused as tightly.

Frequently asked questions

How many games should be in my portfolio?

Three to five finished, polished games beats ten unfinished ones. Add more as you finish them; archive older work that no longer represents your best.

Should I include game jam games?

Yes, if they’re polished. A jam game with a good itch page, a video, and a short reflection on what you built is portfolio-worthy. A jam game in its raw 72-hour state isn’t.

Do I need a video for every project?

Yes, ideally. At minimum, an animated GIF showing core gameplay. Static screenshots aren’t enough to communicate how a game feels.

Should I open-source my games?

For at least one or two portfolio pieces, yes. It signals confidence and lets reviewers verify your code style. You don’t have to open-source everything.

Is a personal site better than itch.io?

For most indie devs, itch.io is sufficient and lower-maintenance. A personal site adds polish but requires upkeep. Don’t let perfect be the enemy of good — itch is fine as a primary.

The bottom line

Browser game dev portfolio tips that actually land jobs come down to a small handful of things: ship more than you build, polish what you ship, present it with a 30-second video and a clear README, and tell a narrative about your growth. The portfolio that signals “I finish things” beats the portfolio that signals “I have ambitious ideas” every time. For an example of an ambitious idea executed with extreme scope discipline, the T-Rex Runner is the model: one mechanic, one screen, one of the most-played browser games of all time.
