How to Start Speedrunning Browser Games

Speedrunning browser games has a lower bar than console speedrunning by a wide margin. No capture card, no emulator config, no specialized hardware. You need a browser, free recording software, and a willingness to do the same level fifty times in a row. This guide walks through the actual steps from “I want to try this” to “I have a verified submission on speedrun.com.”

Step 1: Pick a game and a category

The first decision is which game to run. The friendliest entry points for browser-game speedrunning are games with existing leaderboards, clear categories, and active communities. Popular browser candidates include the Chrome Dino game (score or distance targets), 2048 (fastest to a target tile), Cookie Clicker (milestone runs), and Universal Paperclips (it has a defined ending). Check that the game you pick has an active leaderboard before you start grinding.

Open speedrun.com, search the game’s name, and look at the category list. Each category has its own rules — what counts as the start, what counts as the end, what tools and settings are allowed. Read these carefully. Using the wrong game version or starting the timer in the wrong place are classic reasons for a rejected submission.

Step 2: Watch the top runs before you practice

This is the step new speedrunners skip and regret. Before grinding attempts, watch the current top three to five runs on the category leaderboard. Watch them at full speed first, then again at half-speed if the game supports it. Pay attention to:

• The exact moment the runner starts the timer.
• The route they take through the game — which choices, which order, which skipped sections.
• Tricks or strategies that don’t seem intuitive.
• What they do when something goes wrong — the reset criteria.

Routing is often the biggest factor in early speedrun improvement. A new runner who has studied the routes carefully will usually beat a more reflex-skilled runner who’s improvising. Reflex training comes later; the route is the multiplier.

Step 3: Set up OBS Studio

OBS Studio is the standard recording tool for speedrunners. It’s free, cross-platform, and produces standard video files you can upload anywhere. Download from obsproject.com, install, and open the application.

The minimum setup for browser-game recording:

• Scene: Add a “Display Capture” source pointing to your monitor, or “Window Capture” pointing to your browser specifically.
• Audio: Capture desktop audio (the game’s sounds) and optionally your microphone for commentary.
• Output: Set the recording format to MP4. MP4 is a safe default for uploading to YouTube or Twitch.
• Frame rate: 60fps is standard. Anything lower can cause verification issues on faster games.

Run a test recording before your real runs. Record yourself starting a fresh game, do a quick attempt, and stop. Play back the file and check that the audio and video synced correctly and that there are no dropped frames — a choppy video makes a run hard for moderators to verify.

Step 4: Get a timer

Most browser-game speedruns use in-game time when the game provides it, and external timing when it doesn’t. For external timing, LiveSplit (Windows) is the standard tool. Free, configurable per-game, integrates with OBS as a video overlay. On Mac, Linux and Chromebooks, the browser-based LiveSplit One is a common alternative.

Configure your timer’s splits before your first practice run. A split is a checkpoint within the run — usually a milestone like “first prestige” in Cookie Clicker or “first 100 points” in Chrome Dino. The splits help you identify which sections of the run you’re losing time in. Don’t worry about gold-splitting initially; just set them up so you can see your section times.

Step 5: Run the route until it’s muscle memory

This is the grinding phase. The first attempts at a route feel slow and clumsy, and improvement comes gradually. Eventually the route starts feeling like one continuous motion instead of a sequence of discrete decisions. That transition is the real speedrun skill, and it can’t be shortcut.

A few habits that help:

• Reset early. If a run starts badly, restart immediately rather than playing it out. You’re optimizing learning, not playing for fun.
• Note one improvement at a time. Trying to fix three things at once usually produces worse runs. Pick the biggest time loss and focus on that.
• Track your PB and golds. Personal best is your fastest complete run; gold splits are your fastest segment times. Both are useful — golds tell you what’s theoretically possible if you stitch your best segments together.
• Stop when you’re tired. Speedrunning while exhausted produces sloppy runs and bad habits. Shorter, focused sessions usually beat marathon grinds.

Step 6: Talk to the community before submitting

Games on speedrun.com have a forum, and many active communities also run a Discord. Before submitting your first run, post a message in the appropriate channel introducing yourself and confirming category rules. Veterans are usually happy to help. They’ve seen new runners make the same mistakes — wrong start point, wrong game version, missing audio track — and they’ll tell you about them before verification rejects you.

This step costs nothing and saves hours of frustration. Speedrunning communities are some of the most welcoming corners of the internet to newcomers willing to ask questions.

Step 7: Submit your run

When you have a run you’re proud of, submit it. On speedrun.com, log in, navigate to the game’s category page, and click “Submit run.” You’ll be asked for the video link, the time, the platform, and any category-specific fields. Upload the video to YouTube or Twitch first; speedrun.com doesn’t host video, it just links to it.

The submission goes into a verification queue. Verification can take hours or weeks depending on the game’s moderator activity. While you wait, keep practicing — submitting one run is meaningful, but the goal is to have multiple submissions over time as you improve.

Common beginner mistakes

• Not reading the category rules. Skipping this is the single biggest cause of rejected runs.
• Recording at a low frame rate. A choppy video can make an otherwise valid run impossible to verify.
• Submitting a video where the start and end aren’t clear. Moderators need to see exactly when timing starts and stops; a visible timer overlay helps, and some categories require one.
• Comparing yourself to world-record holders. WR holders usually have years of practice. Your first goal is a clean, verified run, not the top spot.
• Quitting after a few weeks. Improvement is non-linear. Plateaus are normal, and they usually break with steady practice.

Which browser games to start with

Cookie Clicker is a friendly strategy pick — the game is well documented by its community, and early cookie milestones make for clear, well-defined goals. 2048 is another good starting point: the rules are simple and a run has an obvious end, though tile spawns add randomness you’ll have to adapt to.

If you want a reflex-based starting point rather than a strategy one, the Chrome Dino game works — the obstacles are generated randomly but come from a small set of types, and the practice loop is tight. Leaderboards usually specify which version of the game counts (typically the official one built into Chrome), so read the rules carefully; a recreation like ours is fine for practice but may not be accepted for submission. Our guide to Chrome Dino speedrun categories covers the options.

The longer arc

Speedrunning is a long hobby. Climbing a competitive leaderboard can take months or years of practice. The reward isn’t the rank — it’s the focused practice and the community that develops around a shared goal.

Frequently asked questions

Do I need a capture card to speedrun browser games?

No. Browser games run on the same computer you’re recording with, so screen-capture via OBS works fine. Capture cards are only needed when the game runs on separate hardware (console, handheld).

How long until I can submit my first run?

For short browser-game categories, you can submit as soon as you have a clean run that follows the rules. The submission doesn’t need to be world-record — the leaderboard tracks all verified runs.

What software do I need to start?

OBS Studio for recording (free), LiveSplit or an equivalent for timing (free), and a YouTube or Twitch account for uploading the video. That’s it. No paid tools are required.

Can I speedrun on a Chromebook?

Yes, but it’s harder. OBS Studio doesn’t run natively on ChromeOS — you’d use ChromeOS’s built-in screen recorder, a web-based recorder, or try OBS through the Linux environment. Some Chromebook runners record on a separate machine instead.

Is speedrunning browser games considered “real” speedrunning?

Yes. Speedrun.com leaderboards for browser games are moderated the same way as console ones: runs need video proof and must follow the category rules. The scene is smaller than console speedrunning but the standards are the same.

Where to go from here

Pick a game, watch the top three runs on its speedrun.com leaderboard, set up OBS, and start grinding. The first dozen attempts will feel awkward; that’s the universal experience. Submit when you’re proud of a run, not when you’ve matched the world record. The community will meet you where you are. The lowest-friction starting point is right here — open the T-Rex Runner, start a timer, and see how the first practice run feels.
