What’s actually slowing this PC down?

osleague.tools is a web app that its project describes as a hub for Old School RuneScape’s seasonal Leagues game mode, with calculators, relic information, task tracking, and planning. This article covers what the project states it does, what its own documentation leaves unexplained, and what to check before you rely on it for a Leagues route. It describes the project’s stated scope and does not report hands-on testing of the live site.
What the project says the site offers
The project is published as an open repository, and its README is the clearest description of intended features. The README lists four areas: calculators, relic information, task tracking, and planning. Its opening line reads: “Your hub for all your OSRS leagues needs – calculators, relics info, task tracking and planning, and more!” The repository also describes the project as a “Webapp with calculators, trackers, and other tools for Old School Runescape’s seasonal Leagues game mode.”
Read that as the project’s own marketing copy. It tells you what the author intends to build, not how well any feature performs in a given League.
How the tool fits into Leagues route planning
Planning a Leagues route mostly comes down to deciding which tasks and relics to pursue and in what order. The project frames its planning feature as part of task tracking, which suggests that the site is meant to help you organize that work rather than simply list it.

The README does not describe how a route is generated, whether ordering is automatic or manual, or what criteria any ordering uses. Do not assume the site will produce an optimized sequence for you. Confirm what the planner actually does once you open it.
Checks to run before relying on it
Because the project’s description is broad and the repository does not document current League coverage, run these checks yourself:
- League coverage: confirm the League you are playing is listed and not only an earlier season.
- Task and relic coverage: compare the site’s task and relic lists against your in-game task list for the same League.
- Route customization: test whether you can reorder, skip, or annotate items, since a fixed order may not suit your plan.
- Maintenance: the repository does not state an update schedule. Look at its commit history and issue activity to judge whether the tool is kept current.
- Data requirements: note whether any feature asks you to sign in or submit information (see the next section).
Data handling and the Reldo backend
The osrs-reldo/os-league-tools repository states that some high-score, feedback, and user-data functionality depends on the Reldo backend API. That is the only data-related detail in the project material. The repository does not explain whether an account is required, how long any data is kept, or exactly which data is involved.
Until those points are documented, treat any feature that asks for sign-in or submitted data as something whose handling you cannot verify from the project’s own material. Use features that work without an account where possible, and avoid entering information you would not want stored.

What the creator’s post does and does not show
The post was made again after its creator said it had received little attention the day before. That is the poster’s own report. No traffic count or independent measure of use was found, so the post shows that the creator wanted feedback, not how many players use the site or how useful they find it.
Comparing it with other planners
No direct comparison with other route-planning products has been established. If you compare osleague.tools with another planner, check the same things for each: League coverage, task and relic coverage, route customization, data and account requirements, and update cadence. Verify each product’s current support on its own page, because features and League coverage change between seasons.

Who this is for
The project appears most relevant to Leagues players who want one place for calculators, relic information, and task organization, and who are comfortable checking coverage and data handling themselves. Players who need guaranteed current data, a documented privacy policy, or a proven planning algorithm should wait for those details to be published.
