Find the meta for every scenario.
The most complete toolkit for HOI4 strategic planning. Analyze every option, compare every path, and plan every scenario before you hit start.
The players who want the edge.
- You want to immerse yourself in every country you play and tune your strategy around it.
- You optimize a different template for every use case in your run.
- You build content and guides where every stat has to be thought of.
- You want the edge in your next MP game, with every detail planned out.
Compare across every dimension that matters.
Each column is a complete build: template, doctrine, research, and tank equipment. A heatmap highlights the strongest values so the best combination stands out.
Switch from totals to efficiency ratios.
One click switches the stats panel from totals to value-per-cost. Pick IC, manpower, width, supply or fuel when the question is what did I get for what I spent?
- Edits reveal their efficiency tradeoff Every edit shifts every ratio, so you see which stats gained and which paid for the change.
- Switch between IC, manpower, width, and more One tab recomputes the whole panel. No menus, just a tab.
- The right per-cost view for each designer Division: IC, manpower, width, supply. Tank: adds fuel. Ship: its own naval set.

Division, tank and ship designers.
Dynamic sort, tuned to your context.

Before you decide.
Is Pro a fixed feature list, or does it keep growing?
It keeps growing. Hoidesigner has shipped new features on a monthly cadence since launch and that's not slowing down. Pro inherits the same rhythm: new Pro tools ship regularly and every one is included in your membership at no extra cost. You're not buying what's on this page today, you're buying an expanding toolkit that keeps you ahead of the meta as the game evolves.
I don't play MP. Is Pro still worth it for me?
Pro isn't just for MP. It's for the players who love sinking into the systems behind the game: why one template outperforms another, how doctrines and research reshape the stats, what actually makes a build tick. If you're the kind of player who wants to deep dive into the numbers and squeeze more out of every campaign, Pro turns that into an entire layer of the game. If you build one template and run with it, the Free tier is genuinely the right plan and there's no shame in staying there.
Monthly or Annual, which one should I pick?
Annual if you already know you'll use it past two months. At $39.99/yr you save 52% versus monthly and lock the price in for a year. Monthly at $6.99 is the right call if you want to try Pro through one campaign or a few MP matchups before committing. Same features either way, you can switch at any time.
What happens to my designs if I cancel Pro?
Nothing is deleted. Designs within the Free tier's limit stay fully accessible. Anything above the limit is safely stored on your account and locked until you either delete some to free up room, or re-upgrade to Pro. Step away whenever you want, your work is waiting exactly where you left it.
Will the Free tier always exist?
Yes. The Free tier is a permanent part of Hoidesigner and that isn't going to change. Pro is for the players who want more room and sharper tools, not a replacement for what's already free.
How accurate is the data after a patch?
Stats are checked against game files on every release. Things slip through occasionally, but when something's off and a bug report comes in, I usually have it fixed ASAP. Accuracy is the whole point of the tool, so it stays at the top of the list across every tier including Free.
What if Pro isn't what I expected?
On Monthly, cancel any time and you won't be charged again. That's the low-risk way to try Pro for a campaign or an MP game you're planning for the weekend before committing to a year. On Annual, reach out we'll sort it out. Hoidesigner is a solo project, so a real conversation works better than a blanket policy.
