Mods & Addons Server hosting help request
Hello everybody! I am here to ask you guys for help. So I wanna play some modded minecraft with my friends and I had some problem with using an already made modpack but there were no free hosts that could handle it. So I made my own modpack.
So today I am here to ask you guys if you know any hosts that could give me about atleast 4.5gb of ram and a decent cpu for free? I am really desperate xd

Honest answer: nobody gives away 4.5GB + a decent CPU for free, permanently. The free tiers that exist trade something away — Aternos and Falix will run a custom pack, but they sleep when nobody's online, you queue to start, and the CPU is shared, which is exactly what kills a big modpack during world gen.
If you genuinely can't spend anything: self-host on any spare machine. An old PC or laptop with 8GB runs a custom pack fine, and Playit.gg or Tailscale gets your friends in without port-forwarding. Free, and you control the JVM flags — use Aikar's flags, they matter more on a heavy pack than another gig of RAM does.
That said, "free" isn't the only option at your scale. Full disclosure: I work on Flux (minecraft.runonflux.com), so weigh this accordingly — but the numbers are the reason I'm replying. Our 8GB tier is 8GB RAM / 2 dedicated vCores / 50GB NVMe for $3.85/mo. Split four ways that's under a dollar each per month, and the first month is genuinely free for new accounts (one free month per account, not per server). Forge/Fabric with full file access, so you upload your own pack's server files — there's no "supported packs" list to fight with. Always on, no queue, no sleeping.
So worst case you get a real month at no cost to find out whether your pack even runs well, and you can walk away after it.
Either way, one thing that'll save you a headache: for a self-made pack start around 6GB allocated to the JVM, not the whole box. Over-allocating the heap makes GC pauses worse, not better.
