Pricing | About Free Postgres | Deployment

  • Up to 3 shared-cpu-1x 256mb VMs
  • Free Postgres
    • single node, 3gb volume (single database)
    • 2x1gb volumes (database in two regions, or a primary and replica in the same region)

Railway.app

Pricing | Free Trial | Deployment

  • First month: $5 or 500 hours of usage, credit card is not required
  • To get free $5/month - credit card is required and you have to be verified:
    • very active GitHub account
    • active usage on Railway
    • no spammy or abusive behaviour detected
  • Has Postgres, Redis, MongoDB, MySQL
  • Can't run an app 24/7 at a free tier because it offers only 500 hours of usage per month
  • Project deploys are stood down if credit limit OR execution hour limit is reached
  • Need to redeploy projects after the new monthly credit is applied to your account

Pricing | Free Tier Restrictions | Persistence | Github Action

  • Apps are limited to 4000 requests per hour (subsequent requests will return a 429 "Too Many Requests" response).
  • Apps have a limit of 200MB of disk space in the container. The contents of your apps's /tmp directory currently don't count towards that total. Those files are removed when the app restarts.
  • By default your node.js modules don't count towards that total - there's a separate 1GB limit for node modules.
  • There's an additional 512MB of assets storage space. The maximum file size per upload is limited to 256MB.

Adaptable.io

Pricing | Deployment | App requirements

  • 37,500 active CPU seconds per month (625 minutes or 10.4 hours).
  • 25,000 estimated requests/month for typical REST API.
  • Free managed Postgres or MongoDB is included with each app (MS SQL available as add-on).
  • Web services do not support persistent disks. Apps can write to local disk, but files will be lost when the app is scaled down or updated.
  • Web services cannot perform background tasks (HTTP request processing only). App CPU allocation is set to zero when your app is not processing a network request.
  • Web services can be restarted at any time.
  • Apps may be paused for abusive use.
  • Dockerfile support is not yet released.

Cyclic.sh

Pricing | Limits | Deploy

  • Websockets are currently not supported in Cyclic apps.
  • There are no servers, no containers, no images, no hours to count. Each app is deployed entirely on serverless cloud infrastructure.
  • Apps do not have to sleep, wake up, spin up or recycle. All front-ends and back-ends are ready on-demand, immediately and at all times.
  • Storage
    • 1GB of AWS S3 file object storage
    • 1GB AWS DynamoDB NoSQL database.
    • 512MB of ephemeral disk space mounted at /tmp. The data will persist between invokes but there is no guarantee that any further invocations will use the same instance and thus can not be relied on to store persistent data.
  • No streaming of requests or responses
  • 5 API requests per second steady state (for free tier)
  • 10 API requests per second in a burst (for free tier)
