Atlas 1.3.3, published by JakobHellermann, is a specialized visualization tool designed to render and analyze Celeste Tool-Assisted Speedrun (TAS) paths. The utility parses the deterministic movement data generated by Celeste TAS tools and converts it into interactive, color-coded line graphs that overlay the game’s pixel-perfect level geometry, allowing runners, reviewers, and level designers to examine every frame of movement for optimization potential. By accepting standard Celeste TAS input files, Atlas reconstructs the exact trajectory of Madeline or other entities, displaying speed vectors, sub-pixel positioning, and frame-specific inputs so users can identify time-saving corners, dash angles, or unintended detours that would otherwise remain invisible during real-time playback. The renderer supports multiple simultaneous path layers, making it practical to compare alternative routes, ghost runs, or segmented improvements side-by-side; exported PNG sequences or single-frame snapshots can be embedded into documentation, tutorial videos, or submission proofs for speedrun verifiers. Although the catalogue lists three incremental releases, version 1.3.3 remains the current stable build, refining viewport zoom, color palette customization, and memory usage when loading marathon-length inputs. The program sits in the Gaming Tools / Speedrun Analysis category and requires only the .NET 6 runtime alongside an unmodified Celeste installation to function. Atlas is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
