Description

I built bsub because I was tired of wiring up Docker images, Python environments, GPUs, sandboxing, and resource limits every time I needed to run heavy command-line tools from web apps. I wanted: send files -> run job in the cloud -> get output -> done.https://www.bsub.iobsub lets you execute tools like Whisper, Typst, Pandoc, Docling, and FFmpeg as remote batch jobs with no environment setup. You can try them locally via the CLI or integrate via a simple REST API.Example (PDF extraction): bsubio submit -w pdf/extract *.pdf Works like running the tool locally, but the compute and isolation happen in the cloud.Technical details: - Each job runs in an isolated container with defined CPU/GPU/RAM limits. - Files are stored ephemerally for the duration of the job and deleted after completion. - REST API returns job status, logs, and results. - Cold start for light processors (Typst, Pandoc) is low; Whisper/FFmpeg take longer due to model load/encoding time. - Backend scales horizontally; more workers can be added during load spikes.Current processors: SST/Whisper -- speech-to-text Typography -- Typst, Pandoc PDF extraction -- Docling Video transcoding -- FFmpeg More coming; suggestions welcome for tools that are painful to set up locally.Looking for testers! CLI is open source: https://github.com/bsubio/cli. Installers available for Linux/macOS; Windows testing is in progress. Free during early testing; pricing TBD.If you’re on Windows, feedback is especially helpful: [email protected] you try it, I’d appreciate feedback on API design, latency, missing processors, or anything rough around the edges.

Could you build this?

Partial The web UI and dispatch API are simple to vibe-code, but secure multi-tenant microVM sandboxing with GPU passthrough and ephemeral file distribution cannot be created by prompting alone.

What it would actually take: The backend requires an orchestration platform utilizing microVM virtualization (like Firecracker or gVisor) on bare-metal or cloud instances with secure POSIX sandboxing, ephemeral storage mounts, and GPU passthrough (NVIDIA Container Toolkit). The hard engineering piece is sub-second container cold-starts, safe isolation against malicious user code, and efficient file transfer pipelines. It necessitates senior DevOps/infrastructure engineering and systems virtualization skills.
