GameHeads.gg's Blueprint Planner is a browser-based blueprint builder for creating and sharing factory layouts for Arknights: Endfield.

On GameHeads, the layouts you create and save with the planner are called "blueprint plans", to distinguish them from the game's own blueprints (the finished data shared via blueprint codes). Published plans can be browsed in the blueprint gallery.

It helps you turn a factory idea into a buildable layout while organizing the details you normally need to check in-game: facility placement, belt and pipe placement, power coverage, output items, production items, and more.

It also supports planning work that is hard to manage only inside the in-game build screen. With Undo / Redo, autosave, URL sharing, publishable blueprint plans, multi-sheet management, and automatic belt and pipe throughput calculation, you can keep factory layouts in a form that is easy to revisit, share, and improve later.

Because it runs as an external tool, you can test alternative layouts without lowering the output of your current in-game factory, and you can keep thinking through factory designs even when the game is not open.

If you first use the Endfield Calculator to settle your target production rates and facility counts, you can move into the Blueprint Planner with those assumptions in mind while placing facilities.

What is the Blueprint Planner?

GameHeads.gg's Blueprint Planner is a design tool for creating and sharing Arknights: Endfield factory layouts. You can place refineries, assembly facilities, power facilities, belts, pipes, and other factory parts while checking transport routes, power coverage, and the overall factory structure.

In the game itself, you build a factory by placing facilities, connecting belts and pipes, and checking power coverage and output items. The Blueprint Planner brings those factory-design details into the browser while adding features that make design, saving, sharing, and verification easier.

In Endfield factory design, calculating materials and facility counts is not enough by itself. You also need to think about where facilities fit, how belts should run, where pipes can pass, how far power coverage reaches, whether transport capacity is enough, and whether the layout can expand later. The Blueprint Planner is a workspace for thinking through that physical layout in the browser.

Main Features

Core factory-design features

• Place facilities and build a factory layout

• Enjoy factory-layout planning even when the game is not open

This tool is for turning a production plan that works on paper into a factory layout that is easier to build in practice. It handles the placement and transport questions you need in-game, while the browser-based saving, sharing, and verification features make the design easier to revisit, discuss with other players, and improve over time.

How to Use It

1. Open the Blueprint Planner and check the area and size.
2. Choose the facilities you need from the facility palette and place them in the editor.
3. With a facility selected, click the leftmost item icon and choose the item that facility outputs or produces.
4. Use belts and pipes to organize material and liquid transport routes.
5. Turn on power coverage and check whether the required facilities are inside generator range.
6. If needed, adjust production targets in the Endfield Calculator.
7. Once the layout looks right, save, share, or publish it as a blueprint plan.

Published blueprint plans are listed in the blueprint gallery, where other players can search and copy them. If you register the in-game blueprint code, viewers can import it straight into the game.

Common Pitfalls and Tips

• If you start placing facilities before deciding production output, you may need to rebuild later because facility counts or transport capacity are not enough. For larger factories, it is safer to check required recipes and facility counts in the calculator first.
• For belts and pipes, the shortest path is not always the easiest layout to maintain. Leaving room for later expansion makes revisions easier.
• Power shortages can stop the whole factory, so check power coverage after placing generators. If you want to plan the generator setup first, the Battery Optimizer can help.
• When sharing a blueprint plan, a layout that communicates intent is often more useful than one that only packs facilities tightly. Comments and clear structure make the plan easier for others to understand.
• When publishing a blueprint plan, include what it produces, which region it is for, and any notable power or transport choices in the title or description. That makes it easier to find later.

Why Make Blueprints on GameHeads.gg?

The goal of this page is not just to arrange facilities. It is to provide a workspace where you can consider production targets, required facilities, transport routes, power coverage, and transport capacity together while designing a factory layout that can actually run.

Inside the game, you often need to adjust by building directly. But changing an active factory can temporarily lower output or break a working setup. With the Blueprint Planner, you can test another layout without touching the in-game factory, then apply the plan after you are satisfied with it.

You can also think through factory layouts in the browser even when the game is not open. That makes it useful for drafting before a build session, refining ideas during spare time, or reviewing other players' published plans in the blueprint gallery and planning improvements.

As factories get more complex, it becomes more useful to undo experimentation, manage separate areas in the same blueprint plan, and share the design with other players for feedback. GameHeads.gg's Blueprint Planner is built to make that kind of design work easier in the browser.

Factory design can look simple when you only see the finished blueprint, but in practice it usually takes many rounds of adjustment. On GameHeads.gg, you can settle the numbers in the calculator, translate them into a layout in the Blueprint Planner, and then share or publish the result from the same site.

Q&A

What is an Endfield blueprint builder?

It is a browser-based tool for creating Arknights: Endfield factory layouts. You can design blueprints while checking facility placement, belts, pipes, power coverage, production items, output items, and related factory details.

What is the difference between the Blueprint Planner and the calculator?

The Endfield Calculator is for figuring out what to produce and how much to produce. The Blueprint Planner takes that production plan and helps you design where facilities go and how transport routes should connect them.

How is it different from the in-game build screen?

It covers the same core design elements you check in-game, such as facility placement, belts, pipes, power range, production items, and output items, while letting you test alternatives without breaking your existing in-game factory. It also adds planning-friendly features such as Undo / Redo, autosave, multi-sheet management, URL sharing, publishable blueprint plans, and automatic belt and pipe throughput calculation.

Can I share blueprint plans?

Yes. You can share a blueprint plan as a URL or saved plan. If you publish it, it is listed in the blueprint gallery where other players can view and copy it.

Can I specify production items and output items for facilities?

Yes. With a facility selected, click the leftmost item icon to choose the item that facility outputs or produces. Setting recipes and output items makes it easier to understand what each facility is doing on the blueprint.

Can I test layouts without breaking my in-game factory?

Yes. Because you can create alternative layout ideas in the Blueprint Planner, you can consider improvements without changing a running factory in-game. It is useful when you do not want to lose current production output, or when you want to test a large rebuild before committing to it.

Can I use it when the game is not open?

Yes. It runs in the browser, so you can think through factory layouts even when the game is not open. It works well for drafting before building in-game or reviewing other players' published plans while planning your own version.

Can I use it on mobile?

You can view and lightly check layouts on mobile, but detailed facility placement and large blueprint editing are easier on a PC or tablet.
