What It Is

G-Code Analyser is a G-Code analysis tool for 3D printing scenarios. According to the page content, its core goal is to “Analyse your 3D printing G-Code” and provide information such as print time and average speed. Users can upload G-Code by dragging and dropping a file or clicking to browse, then view statistics, per-axis data, and a speed-time histogram on the page.

Core Features and Developer Perspective

Functionally, it is more of a lightweight web tool than a full development platform. The interface provides initial Printer Attribute settings and notes that these fields do not need to be filled in if the corresponding M commands are already present in the G-Code. Users can configure X/Y/Z/E unit-related displays, Absolute/Relative extrusion mode, filament diameter, Feedrate Multiplyer, Look-ahead Buffer Size, and firmware retraction parameters, including retract length, unretract length, retract speed, unretract speed, and Z-Hop height. Analysis outputs include G-Code Statistics, Per Axis X/Y/Z/E statistics, and a Speed-Time Histogram, with views for Move Speed and Fan Speed. The page also offers Settings 1-4 plus settings import and export, making it easier to reuse different printer or material parameter sets.

Pricing, Openness, and Integrations

The captured page text does not mention pricing, subscriptions, payment methods, or enterprise services, so its business model cannot be determined. It also does not state whether it is open source or self-hostable, and there is no visible mention of an API, SDK, CLI, or direct integration with ecosystems such as Cura, PrusaSlicer, or OctoPrint. For developers, this means that based on the public text, it appears better suited to manual analysis than to being embedded into automated workflows.

Pros and Cons

The main advantage is its straightforward workflow: after uploading G-Code, users can quickly get feedback around time, speed, and axis movement. Its parameters cover filament, feedrate multiplier, retraction, and Z-Hop, making it useful for calibrating print-time estimates. The downside is that the page content is almost entirely interface fields, with little documentation, no algorithm explanation, no privacy statement, and no support channels. There is also no information to determine performance with large files or whether processing happens locally in the browser or via server upload.

Who It’s For and Access from China

It is suitable for 3D printing hobbyists, print farm maintainers, slicer-parameter tinkerers, and users who need to quickly inspect G-Code motion characteristics. It is not ideal for enterprise scenarios that require an API, batch processing, team permissions, or compliance documentation. The page provides no evidence about access from China, so this should be marked as unknown; payment information is also not shown. Alternatives include built-in preview and statistics in slicer software, OctoPrint plugins, or other online G-Code viewers.
