Installation Instructions
  1. Visit our GitHub releases page to find the latest downloadable version.
  2. Extract the downloaded zip folder to wherever you'd like to store the application.
  3. Open the extracted folder and open FleaTooltip.exe
    Note: The first time the application is opened you will likely receive a blue warning popup from Windows about the application being unrecognized. The process to digitally sign this kind of application is timely and costly for a hobby project of mine. You will want to click More Info and then Run Anyway to continue. Please review the source code on GitHub if you have any concerns.
  4. Once the application has opened and you can see the overlay in the bottom right you should be all set to try it out in-game. Press F1 to Show/Hide the bottom-right overlay.
    Note: For the application to work, your game must be in Borderless mode.
  5. Either in-raid or in your stash hover over an item until the tooltip appears. Within 100ms-300ms you should see the FleaTooltip overlay appear.
  6. If the application is not working as expected, check out the FAQs below to troubleshoot your issue.

Frequently asked questions

Can't find the answer you're looking for or the application isn't working for you? Reach out to me on Discord.

How does the application work on a technically-simplified level?
  1. When the application starts, it pulls pricing data from either tarkov.dev or tarkov-market.com (if an API key is provided). This data is stored in memory and refreshed every 15 minutes.
  2. The application then waits for your mouse to stop moving for a set duration, indicating you are likely hovering over an item.
  3. Once movement stops, the application looks for specific pixel colors where the Tarkov tooltip typically appears—usually 13 pixels right and 13 pixels up from the cursor.
  4. If a matching pixel color is found, the application calculates the tooltip's dimensions using further pixel detection.
  5. Once the width, height, and position are determined, the application captures a temporary in-memory screenshot of that area.
  6. Using OCR technology, the application scans the image for text. Since OCR isn't always imperfect, the result is fuzzy-searched against the in-memory item database to find the best match.
  7. If a match is found, the application moves the overlay window slightly down and to the right of the cursor and displays the data. When the mouse moves again, the application hides the overlay and clears the previous data to prepare for the next scan.
  8. As a final note about account security: the overlays are standard Windows applications with the title bars removed and the windows made transparent. The main application simply controls their position and visibility. It never interacts with the game process; in fact, you could trigger the overlay by hovering over a static screenshot of the game without even having the game installed on your computer.
Is this a cheat and/or could I be banned for using it?
The application is external and non-intrusive. It functions as a standard Windows overlay, similar to Discord or Spotify, by displaying a borderless window over your screen. Although I can't absolutely guarantee that you won't have any issues, I have personally been using this kind of technology for over 4 years now with no issues and personally don't believe this qualifies as a cheat and/or hack. Check out my previous, now archived project on GitHub, TarkovHandbook, as an example of that.
  • Zero Game Interaction: The app never reads the game's memory, modifies its files, or injects code. It operates entirely by "looking" at pixels on your screen, exactly as a streaming software or a human would.
  • The "Screenshot" Proof: You can trigger the overlay by hovering over a static screenshot of the game with the game itself not even being installed. This proves the application is reacting to purely visual data on your desktop, not the game itself.
  • It Just Simplifies your Existing Workflow: Think of it as a manual Alt-Tab automated for speed. It fetches data and moves a window to your cursor's coordinates—actions that are indistinguishable from standard Windows OS behavior to an anti-cheat system.
Does this application collect any data or have any privacy concerns?
No, the only external network interaction that this application has is on application start (and 15 minute refresh interval) where it fetches the pricing data and then stores it in memory. Other than that network request, the application does not send/receive data. After the initial data fetch, you could go offline and it worked for as long as the application stays open.
The overlay doesn't seem to stay on top of all other applications, it goes away once I focus on any other window (such as Tarkov).
More than likely you will just want to close out the application and reopen it. On the technical side, there is an exe file called setalwaysontop located at “…” that is run on application launch. Sometimes, but rarely, it will fail. You can try running the setalwaysontop.exe while the application is running to see what kind of output it gives / see if it works.
The application isn't scanning anything but it is open and I see the loot total tracker overlay in the bottom right.
Although the application works for most people with no configuration needed on standard monitor sizes (1920x1080/2560x1440), Windows and monitors can differ and aren't always the same. With the application open, simply press F6 to start the scanning setup process and follow the steps it instructs with. If that still isn't working, feel free to contact me on Discord and we can work through it together.
After downloading and extracting the files, the FleaTooltip.exe file isn't there.
More than likely your AntiVirus is deleting the application on extract or preventing it from running all together. If you'd like to continue trying to run the application you will need to setup a manual exception with your AntiVirus software to allow the application to exist/run.
How can I change the default hotkeys?
In the folder that contains the FleaTooltip.exe look for a config.json file. Open that using Notepad or any code editor that you have. Before making any changes, be sure to create a backup of the file contents in case the application stops working correctly after you have made changes. While in there you can edit the following values:
  • TOOLTIP_OFFSET_X: Sets the pixel distance that the tooltip appears away from the cursor on the X-Axis. Should always be a postive value.
  • TOOLTIP_OFFSET_Y: Sets the pixel distance that the tooltip appears away from the cursor on the Y-Axis. Should always be a negative value.
  • TOOLTIP_SINGLE_ROW_HEIGHT: The height of the Tarkov tooltip when it is just a single row of text.
  • TOOLTIP_DOUBLE_ROW_HEIGHT: The height of the Tarkov tooltip when it is two rows of text.
  • OVERLAY_TOGGLE_KEY: The top-row function key that will show/hide the bottom-right total loot tracker. Default is F1. Set to NULL to disable.
  • DELETE_LOWEST_ITEM_KEY: The top-row function key that will remove the lowest value scanned item from the bottom-right total loot tracker. Default is F2. Set to NULL to disable.
  • DELETE_MOST_RECENT_ITEM_KEY: The top-row function key that will remove the most recently scanned item from the bottom-right total loot tracker. Default is F3. Set to NULL to disable.
  • ADD_TO_MOST_RECENT_ITEM_KEY: The top-row function key that will add +1 quantity to the most recently scanned item in the bottom-right total loot tracker. Default is F4. Set to NULL to disable.
  • DISABLE_TOTAL_LOOT_TRACKER_OVERLAY: This will disble the bottom-right total loot tracker entirely. Set to either TRUE or FALSE.
  • TARKOV_MARKET_API_KEY: Optionally, if you are a tarkov-market.com PRO patreon, add your API key from tarkov-market.com to use tarkov-market data instead of the default tarkov.dev data.
Whats the catch? Is this all just free?
No catch whatsoever, I personally have been building this project up while playing the game and at this point I can't imagine playing the game without it. Because of that, I believe that others will feel the same way about it and could benefit greatly from having the help of this application while running raids. And at this point I believe it has reached a state where it is production ready to be shared and enjoyed by others.
I have a suggestion, idea, or issue, how can I get in contact with you?
