Every tool in this space reads the same thing: the .replay file Fortnite writes after your match. That file is not a video. It is the match record — which is both the reason a browser can show you your match with nothing installed, and the reason some questions are permanently out of reach.
This page is the honest version: what comes out of the file, what does not, why these tools break on patch day, and who else works on the format. Checked 21 September 2026.
A replay stores what happened, not pictures of it. The game re-simulates the match to draw it again. So the data is exactly the simulation’s inputs — no more, no less.
That right-hand column is worth holding on to when you compare tools. A replay analyzer that reports on your aim or your editing is inferring it from the left-hand column, not measuring it. There is nothing wrong with an inference as long as it is labelled as one. Those questions belong to a screen recording, which is a different kind of review — see how to review your own Fortnite games.
The replay format travels with the game build. When Fortnite ships a patch, structures inside the file can move, and a parser written against the previous build reads the new one wrongly — or refuses it. This is the same constraint Epic describes from the player’s side: a replay only plays back in the version of Fortnite that recorded it, and old replays stop being valid after an update unless they were saved.
The practical consequence for anyone choosing a tool: the hard part of replay analysis is not the analysis, it is keeping the parser current. A tool that parsed replays beautifully two seasons ago tells you nothing about whether it parses today’s. The only real test is to upload a replay from this week and see whether a report comes back.
On Windows, in one folder. Paste this into the Explorer address bar:
%LOCALAPPDATA%\FortniteGame\Saved\Demos
Several pages that rank for this question give a path under Program Files instead. That is the install folder, not the save folder, and there are no replays in it. More on the folder and the UnsavedReplay naming: where Fortnite saves replay files. On PlayStation and Xbox, Epic documents no way of reaching the file — so there is nothing to upload from a console.
Checked 21 September 2026. Each row is that project’s own description of itself, taken from its own site — not our assessment of it, and not a price comparison. Terms change; check the current ones there.
| Project | How it describes itself |
|---|---|
| Fortiq | Upload the .replay, get a match report in the browser: fights, zones and the moment that cost the match, with a coach you can ask about it. Three full reports a week on the free tier. |
| Royal Arena | “competitive Fortnite intelligence: tournament history, Power Rankings, prize earnings and replay-grade game analysis”, with replays “parsed server-side — nothing to install”. |
| OliTracker | “Fortnite Replay Uploader”. Match Roster — “View all players in your game, including those using anonymous mode” — plus a killfeed breakdown and a cosmetics viewer. |
| Fortnite Tracker | Runs a replay upload tool alongside its stats site. Current availability and limits are stated on their own page. |
| Osirion | A Fortnite improvement platform built around replay data, with its own app and tooling. Their site is the place for current terms. |
| Open-source parsers | The format is also readable directly — FortniteReplayDecompressor and replay-reader are libraries, not products, and need code to use. |
Deliberately absent from this table: pricing, uptime and quality judgements. Prices change faster than a page like this gets updated, and we are not a neutral party on quality — so the fair thing is to point you at each project and let it speak for itself.
The fastest way to judge any of this is one file. Fortiq parses server-side, so there is nothing to install and it works the same on any machine: drop the .replay in, and the report is ready in about a minute. It opens as a web page with its own link, which is also what makes it easy to show a duo partner or a coach — they need no account and no install.
A tool that reads the .replay file Fortnite writes after a match and turns it back into the match record: positions over time, eliminations with location, damage, builds, placement. It works on the file, so it sees the whole lobby rather than only what was on your screen.
Yes — because the match record is in the file, it can be parsed on a server and drawn in a browser with nothing installed. The example report is exactly that, and it opens without signing in.
Crosshair placement, inputs, edit speed and your screen. None of it is in the file, so no tool reads it from one — anything reporting on your aim from a replay alone is inferring. Those questions need a screen recording.
The format travels with the game build, so structures can move on a patch and a parser written for the old build misreads the new one. It is the same reason Epic gives players: a replay only plays back in the version that recorded it. Keeping the parser current is the ongoing work.
Epic documents no way of reaching the replay file on PlayStation or Xbox, so there is nothing to upload from a console. You can still watch the replay in-game there. On PC it is an ordinary file in the save folder.
Three full reports a week, free. Nothing to install, and the report link opens without an account.
