Bundler dependency installation
Shard Cloud installs gems declared in a valid Gemfile during deployment.
Deploy your Ruby app, worker, or bot with Bundler.
Host Rails, Sinatra, Sidekiq, discordrb, or another Ruby project from GitHub or ZIP/RAR. Shard Cloud installs declared gems, then runs the entry point or custom command you configure.

Ruby workload examples
From Rails applications to workers and bots.
Deploy the Ruby source files and Gemfile your project needs, then configure the production process that should remain running.
Explore capabilitiesRails and Sinatra applications
Run a Rails application with a custom command or deploy a Sinatra API with the source files and runtime configuration it requires.
Sidekiq and background processes
Deploy a Ruby worker process with its own start command and use application logs and metrics to monitor it.
Ruby bot processes
Run a Ruby bot as a long-running application process, keeping its token in environment variables and following output in logs.
Built to operate
Ruby hosting for web processes, workers, and bots.
Install declared gems, configure the production command, and operate the Ruby process with persistent storage, domains, logs, metrics, and restart support.
Choose a Ruby runtime version
Select a supported Ruby version from the live runtime catalog when creating the application.
Persistent application files
Keep Rails uploads and other Ruby-generated files on the 10 GB persistent disk at /app.
Publish an HTTPS address
Ruby web applications receive a free HTTPS address under *.shardweb.app; custom domains require Core or higher.
Logs and resource metrics
Use logs with memory and CPU metrics to inspect Bundler installation, Rails startup, and Ruby process output.
Automatic restart
Ruby application processes restart automatically; inspect dashboard logs when a configured command stops.
Deployment setup
How to deploy a Ruby application on Shard Cloud.
Prepare the source files and Gemfile, choose the Ruby runtime and production command, then verify the running process.
Get started01
Prepare the project
Include app.rb or main.rb, a Gemfile and .shardcloud. Remove vendor/bundle/, .bundle/, tmp/ and log/.
02
Configure the start command
Shard Cloud installs your gems on deploy. A Rails app sets MAIN=Gemfile and a CUSTOM_COMMAND that boots the server.
03
Verify the process
Test a route, job or bot event, then review logs.
From connection to the first decision, in one flow.

Frequently asked questions about Ruby hosting
Include a valid Gemfile. Shard Cloud installs its gems during deployment.
Set CUSTOM_COMMAND=chmod +x bin/rails && bin/rails server -b 0.0.0.0. Configure Puma to bind to the application's port.
No. Run db:migrate or assets:precompile in a custom command, or run asset precompilation before upload.
Sidekiq normally needs Redis. Shard Cloud offers managed Redis with TLS-only connections; configure the worker's connection values and start command for your project.
Set VERSION=LATEST for the newest supported Ruby release, or VERSION=recommended for the platform's recommended release. Choose the setting compatible with your Gemfile and application.
Every app needs at least 256 MB. Use 512 MB or more for a public website or API, then increase it based on observed usage.
Your server must listen on port 80.
