Modal — Key features
- Usage based billing: Pay for compute while the function runs with a Starter plan that has $0 base fee and includes monthly free credits
- Web endpoints: Expose a deployed Python function over HTTP so non Python clients can call it as an API
- Crons and schedules: Run batch jobs on a schedule for ETL retraining or reports without keeping servers online
- Secrets management: Store credentials securely and inject them into containers via dashboard CLI or Python to avoid hardcoding keys
- Volumes storage: Use distributed volumes for write once read many assets like model weights shared across inference replicas
- Containerized functions: Package dependencies into images so your runtime is reproducible across local dev and production
Streamlit — Key features
- Python-first apps: Build interactive web apps from Python scripts without writing a separate frontend codebase
- Fast iteration loop: Automatic reruns during development help you iterate on UI and logic quickly with stakeholders
- Interactive widgets: Add inputs like sliders and selectors to turn static analysis into usable tools for teams
- Charts and visuals: Render data visualizations directly in the app to support dashboards and exploratory analysis
- Open-source framework: Use Streamlit as an open-source library with a large ecosystem and community examples
- Community Cloud hosting: Deploy apps via Streamlit Community Cloud described as totally free for quick sharing
Modal — Best for
- Inference API: Deploy a model as a web endpoint that scales with traffic and shuts down when idle to control cost
- Batch embedding jobs: Run scheduled batch workloads to generate embeddings or features without managing a long running cluster
- Data pipelines: Execute Python ETL steps on a cron schedule and persist outputs to volumes for downstream jobs
- Prototype to production: Turn a notebook experiment into a containerized function with the same dependencies and reproducible runs
- Internal tools: Build lightweight HTTP utilities around Python code for analytics ops or content pipelines
Streamlit — Best for
- Internal dashboards: Turn notebooks into lightweight dashboards for teams that need daily metrics and exploration
- Model demos: Ship ML and LLM demos to collect feedback and validate usefulness before production integration
- Data exploration tools: Create interactive filters and charts so analysts and stakeholders can explore datasets safely
- Ops utilities: Build small admin and ops apps for monitoring workflows without a large web engineering effort
- Client prototypes: Share a proof of concept data app to align requirements before investing in a full product
