RamShared
Use idle GPU VRAM as safe swap space on Linux & WSL2
RamShared borrows idle GPU memory as a high-speed swap cushion on Linux & WSL2—without freezing your OS. Unlike naive GPU swap tools that crash during memory eviction, RamShared uses a crash-safe cascading tier: • zram (compressed RAM) • GPU VRAM (cushion) • NVMe (last resort) Features active latency canary monitoring, automatic page demotion, and Rust-native safety via ublk/NBD drivers to keep your machine responsive under heavy loads.
Hey Product Hunt! 👋
I'm Emerson, creator of RamShared.
If you compile large codebases, run Docker containers, or spin up local LLMs, you’ve probably hit the dread of system thrashing when RAM runs out. Meanwhile, your dedicated GPU might be sitting right next to it with 8GB–16GB of completely idle VRAM. You paid for that silicon—why not use it?
### The Problem with "Just put swap on the GPU"
Many have tried putting swap on GPU VRAM, but under host memory pressure (especially on WSL2/Windows WDDM), graphics memory eviction can spike read latency up to ~1.2 seconds. If VRAM is your primary swap, your entire desktop freezes.
### How RamShared Fixes This
RamShared treats GPU memory not as primary RAM, but as a cautious second-tier cushion:
* Cascading Priority: Data goes to zram first (fastest). Only colder pages spill into VRAM before eventually hitting disk.
* Active Canary Checks: If VRAM latency spikes or the host claims graphics memory, RamShared silently demotes pages to disk and unloads the tier safely—keeping your system responsive.
* Crash-Safety: Built in Rust around reliable kernel driver layers (ublk/NBD) so daemon drops won't freeze your OS.
It’s open-source, lightweight, and ready for Linux & WSL2 users.

Who hunted RamShared?
RamShared was hunted by EMERSON BUSSON. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
