What QuickMDSim is — and why we're building it

If you write LAMMPS inputs, you already know the gap between the idea and the finished job. That gap is what we're building to remove.

What QuickMDSim is

QuickMDSim is a browser-based workbench and job runner for LAMMPS molecular dynamics simulations. The core loop is intentionally small and familiar:

1. Create a project — inputs, jobs, and outputs stay together.
2. Edit the input script — real LAMMPS, in the browser. No toy GUI forced on you.
3. Submit a job — it goes on a queue and runs in the cloud.
4. Download results — logs and artifacts when the job finishes.

You pay in CPU-hour credits you can understand — not mystery instances. Start free with a small seed of compute, and scale when the science needs it.

Why we're building it

We kept watching the same story repeat: a grad student with a perfectly good input script spending a week — not minutes — before they see any trajectory. Not because the physics was hard, but because of everything around it:

• Cluster queues and modules. Submit, wait, pray the module loads. Reproducible only if the sysadmin had a good day.
• Cloud plumbers. Want it on AWS? Here's a Terraform module, a YAML file, and a surprise bill next month.
• A laptop that can't run overnight. The simulation finishes, but you were asleep and it died at step 40,000.

None of that is science. It's infrastructure time — the one thing a researcher is worst positioned to spend. Our working principle is simple:

Scientist time > infrastructure time. Every feature should shorten the path from idea to trajectory.

Who it's for

People who already know LAMMPS. We're not replacing force fields or the physics — and we're not pretending to. We fit the workflow you already have:

• Graduate students and postdocs who write inputs daily and hate queue politics.
• Small academic labs that don't want to run a mini-HPC.
• R&D teams that run occasional validation sims and don't want DevOps on the side.
• Course labs that need many short, isolated jobs during the semester.

Honest scope

We're early, and we'd rather be specific than impressive. QuickMDSim is a focused LAMMPS workbench and job runner. It is not:

• An "AI drug discovery" pitch — there's no hype tax here.
• A click-and-drag GUI builder that hides the input language from you.
• A replacement for a national-lab cluster at 10,000-core production scale.

The app is live, the project → file → job → output workflow works today, and a free tier gives you a starter amount of compute after you verify your email. Real LAMMPS container execution is the next milestone and we'll be honest when that lands — you can hold us to it.

The mission

Make serious molecular dynamics accessible in minutes, not after a week of environment setup, queue politics, or cloud-bill anxiety. If you already write LAMMPS inputs, QuickMDSim is the fastest respectable path to a finished job.
