Heroku vs IONOS

What Heroku is

Heroku is a proprietary platform as a service that builds and runs applications in managed dyno containers, with pipelines, logs, data products and marketplace add-ons. Eco provides 1,000 shared personal-account dyno hours for $5 monthly and sleeps inactive web apps; Basic and larger dynos are usage-prorated up to published monthly caps. Dyno filesystems are ephemeral, so durable state belongs in databases or object storage. Compute, data services, add-ons, CI, support and private networking must be costed together.

What IONOS is

IONOS sells domains, shared web hosting, WordPress, VPS, cloud and dedicated products; this record focuses on US Linux shared Web Hosting. Current tiers bundle a domain, SSL, professional email, SSH/SFTP/WP-CLI, databases, one-click apps, daily backup/restore and 24/7 support. Promotional one-year prices rise to disclosed monthly renewal rates, taxes apply, and apparently unlimited sites, storage or databases remain bounded by shared compute, file-count and acceptable-use constraints.

What Heroku is built to do

Managed dynos

Runs isolated application processes with platform-managed cycling and replacement.

Release workflow

Builds deployable releases and supports pipelines, review apps and one-off administrative processes.

Data and add-ons

Attaches Heroku data products and third-party marketplace services to applications.

Runtime tiers

Offers sleeping personal Eco dynos through always-on production and isolated Private/Shield options.

What IONOS is built to do

Shared hosting tiers

Allocates websites, geo-redundant storage, databases and compute levels by plan.

Developer tools

Includes SSH, SFTP, WP-CLI and database access for supported web projects.

Bundled operations

Provides SSL, DDoS protection, daily backup/restore and 24/7 support.

Account mobile app

Offers iOS and Android account functions such as notifications and payment-detail management.

Choose Heroku if

• Conventional stateless web and worker applications needing fast deployment and managed runtime operations
• Small experiments on Eco where sleep and the shared 1,000-hour pool are acceptable
• Production services after sizing dynos, databases, add-ons, regions and support as one bill

Skip Heroku if

• The application needs persistent local disk, privileged host access or unusual infrastructure control
• Cold starts, a single Eco dyno per process type or hour exhaustion are unacceptable
• Data residency is assumed from the app region without reviewing control-plane and add-on behavior

Choose IONOS if

• Conventional PHP, database and WordPress sites that fit shared resource and file limits
• Buyers who value domain, email, SSL and hosting in one provider account
• Projects whose full first-year and renewal costs have been documented before purchase

Skip IONOS if

• The application needs root access, persistent custom daemons or guaranteed compute isolation
• The website is expected to exceed file, database, CPU or memory limits despite an unlimited label
• No independent export, backup, domain-transfer and cancellation procedure is maintained

Heroku: pros & cons

• Managed runtime: Heroku handles container placement, restarts and underlying operating-system administration.
• Simple release model: Source or container deployments, configuration variables and one-off commands support repeatable application delivery.
• Integrated ecosystem: Pipelines, review apps, Postgres, Key-Value Store and marketplace add-ons reduce integration work.
• Granular billing: Most dynos and data add-ons are prorated to the second up to a monthly maximum.
• No general free compute tier: Eco costs $5 monthly, is personal-app only and can exhaust its shared hour pool.
• Eco cold starts: Inactive web dynos sleep after 30 minutes and wake with a delay.
• Ephemeral local disk: Files written at runtime disappear across restarts, deploys or dyno replacement.
• Stacked cost: Production dynos, databases, add-ons, CI, teams and support can materially exceed the headline compute price.

IONOS: pros & cons

• Broad bundle: Domain, SSL, email, databases, SSH tools, app installation, backups and support are packaged together.
• Published renewal figures: Plan cards show first-year discounts and the subsequent monthly price.
• Developer access: SSH, SFTP and WP-CLI support conventional PHP and WordPress workflows.
• Product ladder: Shared, WordPress, Deploy Now, VPS, cloud and dedicated services cover different control requirements.
• Promotional discontinuity: The $1 Plus offer requires a one-year term and then rises to $14/month at the reviewed date.
• Shared-hosting limits: CPU, memory and a 262,144-file ceiling constrain even plans marketed with unlimited resources.
• Bundle complexity: Domains, email, hosting and optional products can renew on separate terms and require cancellation planning.
• Backup scope needs verification: Included daily restore does not remove the need for off-provider file and database copies.
