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 ISPConfig is
ISPConfig is a free, BSD-licensed control panel for administering Linux web, mail, DNS, database, FTP, shell and cron services. One panel can manage a single server, multiple servers or mirrored configurations, with separate administrator, reseller, client and email-user access levels. The core software has no license fee, but servers, administration, monitoring, backups and incident response remain the operator's responsibility. Optional materials and extensions use separate commercial terms: the current billing module is €59 excluding VAT per master panel and includes 12 months of updates.

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
Choose ISPConfig if
- Self-managed Debian or Ubuntu hosting estates with experienced Linux operators
- Hosting providers needing reseller and client delegation across several servers
- Teams prepared to automate backups and test service-by-service restoration
Skip ISPConfig if
- You need a fully managed SaaS control plane with infrastructure and recovery included
- No one owns OS patching, mail reputation, DNS, TLS, monitoring and incident response
- A proprietary billing add-on or paid support is assumed to be included with the free panel

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.
ISPConfig: pros & cons
- Open and inspectable: The core panel is distributed under the permissive BSD license.
- Multi-service administration: Web, mail, DNS, databases, users, quotas and monitoring are managed from one interface.
- Multi-server support: A single control plane can administer multiple servers and mirrored configurations.
- Role separation: Administrator, reseller, client and email-user levels support hosting-provider workflows.
- Self-hosted responsibility: Installation, OS hardening, patching, capacity, backups and recovery belong to the operator.
- A panel is not isolation: Secure tenant boundaries still depend on the underlying Linux services and configuration.
- Commercial extras differ: Billing, manuals and professional installation or update support are not part of the free core license.
- Migration needs proof: Existing sites, mailboxes, DNS zones and databases require service-specific validation and rollback.
Our verdict on IONOS
IONOS shared hosting fits standard small sites, but select it using the post-promotion price and concrete resource limits; separate domain/email obligations, export independent backups, and move to VPS or cloud when shared hosting no longer matches the workload.
Our verdict on ISPConfig
ISPConfig is a capable free control panel for experienced Linux teams, particularly in multi-server hosting, but its zero license price should never be confused with zero operating cost; harden the underlying services and prove backup, update and migration procedures before production.
