The best Streamlit hosting in 2026 depends on your constraint: Render or Railway if you want cheap always-on, Posit Connect Cloud if you're an R+Python team, Streamlit in Snowflake if your data lives there, and Fastero if you need auth without building auth.
Community Cloud: what you actually get in 2026
Community Cloud is free, official, and still the default first deploy for most Streamlit apps. Here is what free actually means today.
Sleep. Apps with no traffic for 12 hours go to sleep. Visitors see a "Zzzz" screen and must click to wake the app — cold starts take 30 seconds to over a minute. Commits to the repo no longer wake a sleeping app, so scheduled Git pushes are not a workaround anymore.
RAM. The documented ceiling is approximately 2.7 GB (with a 690 MB floor). If your app plus dependencies exceed that, it crashes and restarts with no warning. Large Pandas DataFrames reliably hit this wall once Streamlit's own overhead is counted.
Auth. Streamlit shipped st.login() with OIDC support — Google, Entra, Auth0, and Okta are all supported. You can also gate access to members of a GitHub organization. One private app is allowed per account.
Custom domains. Not supported. Your app lives at your-name.streamlit.app.
Fair-use blocks. Accounts can be locked with a 403 error for exceeding undocumented usage limits. This has triggered during normal deploy-and-fix cycles — dozens of forum threads report it since mid-2025.
Best for: Open-source demos, course projects, and personal prototypes where cold starts and a single private app are acceptable.
Streamlit in Snowflake
If your data already lives in Snowflake, this is the most natural option — your app runs inside the warehouse and reads tables without an external connection.
Pricing. Billed in Snowflake credits, not a flat monthly fee. Compute pools or warehouse time are consumed while the app runs. The dollar cost depends on your Snowflake edition and region.
Auth. Snowflake roles control access, and viewer URLs can redirect through your organization's identity provider. Strong access control — but every viewer needs a Snowflake account or identity provider linked to one.
Limitations. Apps can only query Snowflake data. If you need to hit a Postgres database, an API, or a local file, this is the wrong host. The warehouse runtime suspends after about 15 minutes of viewer inactivity.
Best for: Teams already on Snowflake who want dashboards and data to live inside one perimeter.
Fastero
Connect your database. Ask questions. Get dashboards.
Postgres, BigQuery, Snowflake, and 10+ sources — live-connected, AI-powered, no dashboard builder learning curve.
Try free →Posit Connect Cloud
Posit (formerly RStudio) hosts Streamlit alongside Shiny, Quarto, and Jupyter — a strong fit if your team works across R and Python.
Pricing (Sep 2026). Free: public apps from public repos, 4 GB RAM, 5-app limit. Basic $19/mo: private repos, 8 GB, 25 apps. Enhanced $59/mo: private link sharing, 16 GB, 1 custom domain. Advanced $249/mo (includes 5 seats): email-authenticated sharing, RBAC, 5 custom domains. Every person who logs in consumes a seat.
Auth. Meaningful viewer authentication starts at the $249/mo tier. The $59 tier offers private links anyone with the URL can open — useful but not gated.
Best for: R+Python data teams that already use Posit tools and need shareable apps with role-based access.
Hugging Face Spaces
Hugging Face deprecated its native Streamlit SDK. Streamlit apps now run as Docker Spaces.
Pricing (Sep 2026). Creating a Docker Space requires at least a PRO plan ($9/mo) or Team ($20/user/mo). The free CPU Basic hardware (2 vCPU, 16 GB RAM) is available once you have PRO. Free Spaces sleep after 48 hours of inactivity.
Auth. Private Spaces are visible only to the owner and collaborators with HF accounts. No SSO or role-based sharing outside the HF platform.
Best for: ML teams already on Hugging Face who want to ship a model demo without leaving the platform.
Render
Pricing (Sep 2026). Starter $7/mo (512 MB, 0.5 CPU). Standard $25/mo (2 GB). Pro $85/mo (4 GB). Free-tier web services sleep after 15 minutes — far more aggressive than Community Cloud. Paid instances are always-on.
Auth. None built in. You would need streamlit-authenticator or a reverse proxy.
Custom domains. Included on paid plans. Secrets management is built in.
Best for: Developers who want a cheap, always-on deploy and are comfortable adding auth at the application layer.
Railway
Pricing (Sep 2026). Hobby plan: $5/mo base + usage-based billing for RAM and CPU. A small Streamlit app typically costs $10–25/mo total. Pro plan: $20/mo base + usage, with team features. No sleeping on paid plans.
Auth. None built in — auth is your responsibility. Secrets management is included.
Custom domains. Included on paid plans.
Best for: Solo developers or small teams who want usage-based billing and don't need viewer login.
Heroku
Pricing (Sep 2026). Eco $5/mo (512 MB, sleeps after 30 minutes). Basic $7/mo (512 MB, always-on). Standard-2X $50/mo (1 GB). The developer experience is mature but the value has not kept up — Render and Railway offer more RAM per dollar.
Auth. None built in. Custom domains: Supported.
Best for: Teams with existing Heroku infrastructure. For a new Streamlit deploy, Railway or Render is usually a better deal.
Fly.io
Pricing (Sep 2026). Shared-cpu-1x with 256 MB: $1.94/mo. With 1 GB: $5.92/mo. Docker-based deploy — you write a Dockerfile and run fly deploy. Billed per second, no sleeping.
Auth. None built in. Custom domains: First 10 SSL certificates free.
Best for: Developers comfortable with Docker and CLI tooling who want per-second billing and full control over the container.
Self-hosted on a VPS
A $5–15/mo VPS (DigitalOcean, Hetzner, Linode) running Docker, nginx, and Let's Encrypt gives you an always-on Streamlit app with no platform limits.
Auth. Whatever you build — OAuth2 Proxy, Cloudflare Access, or Authelia in front of nginx. Works, but it is yours to maintain.
The real cost. nginx WebSocket config trips up most people — miss the Upgrade header and Streamlit shows "Connecting..." forever. SSL renewal, process supervision, and security patches are ongoing work. The $5/mo buys the server, not the ops time.
Best for: Teams with DevOps capacity, compliance requirements, or apps that need 8+ GB of RAM.
Fastero
Fastero hosts Streamlit apps with authentication and secrets management as first-class features, not add-ons.
Pricing. Free tier gives you 1 GB RAM per app with built-in auth and secrets. Paid plans start at $20/month and unlock compute tiers up to 16 GB RAM per app.
Auth. Built in by default. Every app sits behind your organization's login. Invite colleagues as viewers by email — no streamlit-authenticator code, no OAuth proxy, no GitHub-org gating. Access control works the moment you deploy.
Secrets. Encrypted vault accessible via the standard st.secrets API — same code you would write for Community Cloud. No Fastero-specific imports.
Always-on. No cold starts, no sleeping. The app is running when someone visits it.
Custom domains. Supported on paid plans.
Deploy. Import from a GitHub, GitLab or Bitbucket repository — private repos included — with your requirements.txt, pick the app's Python version, set your secrets, deploy. Edits you make in Fastero go back to the repository as a pull request, so Git stays the source of truth. An AI assistant can edit your app's code directly from the platform.
Database connections. An app can read one of your workspace's connections through st.connection, picked when you create the app — no credentials in your code or your repo.
Start-up logs. When a start fails, you see the last lines of its output in the app's workspace, and so does the AI assistant fixing it.
Who opened it. Owners and admins see who opened each app, so you know the dashboard you shipped is actually being used.
Deploy from Claude. With the Fastero connector, Claude Code or claude.ai can create the app, write its files, start it and hand back the link your team opens.
Best for: Teams that need auth without building auth, apps handling larger datasets (up to 16 GB), and use cases where the Streamlit app lives alongside broader data workflows.

How to choose
Start with the constraint that matters most:
- Need login for viewers? Fastero (from $20/mo with org login, always-on, up to 16 GB), Posit Connect Cloud ($249/mo for email-authenticated sharing), or Streamlit in Snowflake if your data is already there.
- Need cheap always-on and no auth? Render Starter ($7/mo) or Railway Hobby (~$10/mo).
- Need more than 4 GB RAM? Self-host on a VPS, or use Posit Connect Cloud Enhanced ($59/mo, 16 GB).
- Data lives in Snowflake? Streamlit in Snowflake — skip the external connection entirely.
- Just need a public demo? Community Cloud still works fine for that.
How to move a Community Cloud app to Fastero
Your app does not change. The same repository, the same requirements.txt, the same st.secrets calls:
- Create the app from your repository. Paste the repo URL and branch — GitHub, GitLab or Bitbucket. A private repo takes an access token.
- Copy your secrets across. Each line of your
secrets.tomlbecomes a Fastero secret. A dotted name keeps its section: a secret namedconnections.snowflake.userreads back asst.secrets["connections"]["snowflake"]["user"], exactly as on Community Cloud. - Pick the Python version and start it. If a package fails to install, the start-up log shows you which one.
- Invite the people who should see it. They sign in with their own login and land on the app.
FAQ
How do I move an app off Streamlit Community Cloud?
Point the new host at the same repository and copy your secrets across. On Fastero that is four steps — import the repo, add the secrets (dotted names keep their st.secrets sections), pick the Python version, invite your viewers — with no code changes, as in the steps above.
What should I use instead of Streamlit Community Cloud for a team app? If the issue is that colleagues need to log in, Fastero ($20/mo) gives you org login and always-on hosting by default. If the issue is only sleeping, Render ($7/mo) or Heroku Basic ($7/mo) keep your app running around the clock.
Is there a free Streamlit host that doesn't sleep? No. Every free tier — Community Cloud, Render, Hugging Face — puts inactive apps to sleep. The cheapest always-on option is Fly.io at $1.94/mo (256 MB) or Heroku Basic at $7/mo.
Can I add login to a Streamlit app without writing auth code?
Yes. Community Cloud now supports st.login() with OIDC providers like Google and Entra. Fastero puts every app behind org login automatically — no code changes needed. Posit Connect Cloud offers email-authenticated sharing on its $249/mo plan.
Does Hugging Face still offer free Streamlit hosting? Not directly. Streamlit apps on Hugging Face now run as Docker Spaces, and creating a Docker Space requires a PRO plan ($9/mo). The compute hardware can be free once you have the plan, but the plan itself is not.
