Solidtime and Clockify are often compared for teams that require reliable time tracking. The choice matters for compliance, costs and technical control. This guide provides a direct comparison of features, a step-by-step migration path, self-hosting instructions, integrations, security and a multi-year cost analysis tailored for teams in England and the EU. Emphasis on practical, verifiable steps enables confident decisions without guessing.
Feature-by-feature comparison: solidtime vs Clockify
Core tracking and UX
- Time capture: Clockify offers web timer, desktop and mobile apps with offline sync; Solidtime commonly provides a lightweight web timer and self-hosted clients where available. User experience differs: Clockify aims for zero-setup; Solidtime favors control and customization.
- Reports and billing: Clockify includes built-in invoicing and prebuilt reports. Solidtime usually provides configurable reports and may require additional setup for invoices when self-hosted.
- User limits and pricing model: Clockify features a generous free tier for teams. Solidtime, as an open-source option, often removes per-user license constraints but introduces hosting and maintenance costs.
Integrations, API and automation
- Out-of-the-box integrations: Clockify integrates natively with tools such as Jira and Slack. For documentation see Clockify integrations.
- Solidtime integrations: Integration capabilities depend on available adapters or community plugins. Connections to Slack, Jira and Zapier are usually implemented via APIs or middleware; reference general integration platforms at Zapier, Slack and Jira.
- API maturity: Clockify provides documented REST APIs. Solidtime's API surface depends on its project state or community forks; evaluate the GitHub repo and API docs before committing.
Security, compliance and hosting
- Data residency: Clockify hosts data in cloud regions; for EU-focused hosting and GDPR, verify plan options and data centers. See GDPR overview at gdpr.eu.
- Self-hosting advantage: Solidtime allows the option to host within EU infrastructure to satisfy legal or internal policy requirements.
- Best practice sources: Use ENISA guidance for secure cloud setup ENISA and OWASP recommendations OWASP.

Migration: step-by-step from Clockify to Solidtime
Pre-migration checklist
- Export data: Use Clockify export tools (CSV/JSON) for time entries, projects and clients. Reference export docs at Clockify export.
- Inventory integrations: List active integrations (Slack, Jira, Zapier) and prioritize re-implementation.
- GDPR and contracts: Review data processing agreements if planning to self-host in the EU; see recommended reading at gdpr.eu.
Field mapping and import strategy
- Map user IDs, project codes, tags, and rates. Create a CSV template matching Solidtime's import schema.
- If Solidtime lacks a native importer, use scripts that transform Clockify JSON to the expected format. A reliable pattern: export → validate with sample imports → full import during maintenance window.
- Maintain audit logs of the migration and keep original exports encrypted and stored for compliance.
Testing and cutover
- Run a pilot import with a subset of users and a read-only parallel phase for two weeks.
- Verify reports, billing accuracy and integration triggers before final cutover.
- Communicate schedule and rollback plan to stakeholders.
Self-hosting Solidtime: installation, maintenance and scaling
Recommended deployment (Docker + reverse proxy)
- Use Docker Compose for controlled deployments. Follow general container guidance at Docker docs.
- Recommended stack: app container, PostgreSQL, Redis (optional), Nginx reverse proxy with TLS (Let's Encrypt). Apply automatic backups for DB and file storage.
Backups, updates and monitoring
- Implement nightly database dumps, weekly offsite snapshots and test restore procedures.
- Automate updates using CI or scheduled pipelines, and apply security patches promptly. Monitor using Prometheus/Grafana or hosted monitoring.
- For small teams (up to 100 active users) a single medium VM (4 vCPU, 8GB RAM) is often sufficient. For larger organizations, scale DB and app horizontally.
- Run load tests before production; capture metrics like concurrent timers, DB index utilization and response latency.
Integrations, API examples and automation scripts
Typical integrations
- Slack: send start/stop notifications or weekly summaries. Use Slack's API api.slack.com.
- Jira: link time entries to issue keys. Use Jira REST API guidelines at Atlassian dev.
Example automation pattern
- Automation: On closing a Jira issue, create a time entry via Solidtime API. Implement as webhook receiver that translates Jira payloads to Solidtime REST calls.
- Provide retry logic and idempotency keys to avoid duplicate entries.
Security, GDPR and legal considerations for England and EU
Data protection checklist
- Host within an EU or UK data center if DPA requires data residency. Use encryption at rest and in transit (TLS 1.2+).
- Maintain records of processing activities and Data Processing Agreements (DPAs) where third-party processors are used.
Standards and references
- Consult ENISA publications for cloud security best practices: ENISA.
- Use NIST guidance for incident response and cybersecurity controls: NIST.
Cost comparison and TCO (1/3/5 year view)
Key cost factors
- Clockify: subscription costs for paid tiers, per-user fees for advanced features, managed hosting included.
- Solidtime self-hosted: hosting (VMs, storage), maintenance (engineering hours), backups, monitoring, and possible paid support.
Sample TCO scenario (estimates for 2026)
- Small team (20 users) — Year 1:
- Clockify Pro: ~£1500/year (approximation for paid plan)
- Solidtime self-hosted: Hosting £300/year + maintenance £4,800/year (10h/month at £40/h) = £5,100/year
- Break-even shifts as team size grows and with higher Clockify per-user costs. For privacy-sensitive organizations, hosting control may justify the premium.
Real-world UX and adoption considerations
Adoption risk factors
- Change resistance: Teams used to zero-setup tools can resist self-hosted workflows.
- Support SLAs: Commercial support for Solidtime may be limited; plan for internal or vendor SLA.
Mitigation tips
- Provide training sessions, quick-start guides and a temporary overlap period where both systems run in parallel.
Expert citations and verifiability
- Use ENISA and NIST resources for security baselines: ENISA, NIST.
Frequently asked questions (FAQ)
What are the main reasons to switch from Clockify to Solidtime?
Switch drivers include a need for data residency, open-source licensing, elimination of per-user licensing or deep customization. If hosting control and GDPR alignment are priorities, Solidtime can be preferable.
Is data migration from Clockify straightforward?
Exports from Clockify are available in CSV/JSON. Migration is straightforward for time entries and projects but requires careful field mapping and testing for integrations and billing data.
Can Solidtime match Clockify integrations?
Solidtime can integrate with major tools via APIs and middleware, but native integrations may be fewer. Zapier, custom webhooks and integration layers bridge most functional gaps.
Does self-hosting increase security risk?
Self-hosting increases responsibility for security. Proper patching, backups, TLS configuration and monitoring are required. Guidance from ENISA and OWASP is recommended.
What is the typical cost trade-off over five years?
Self-hosting often has higher initial and maintenance costs but may reduce per-user licensing fees and provide long-term savings for large teams. A TCO model should include hosting, maintenance, support and opportunity costs.
Are there managed vendors for Solidtime?
Community-supported projects sometimes have third-party vendors providing managed hosting and SLAs. Evaluate vendor credentials and references before procurement.
How to ensure GDPR compliance when switching?
Document processing activities, update DPAs, choose EU/UK hosting, perform DPIA if necessary and keep migration logs encrypted and access-controlled.
What test plan should be used before a full cutover?
Run a pilot with representative users, validate report parity, test integrations end-to-end and keep a rollback strategy that restores the previous system within a defined SLA.
Conclusion
Choosing between solidtime vs Clockify depends on priorities: control, compliance and customization favor Solidtime when self-hosted; ease of use, managed scaling and native integrations favor Clockify. For teams in England and the EU that require data residency and auditability, a phased migration with thorough testing, clear field mapping and a documented TCO will minimize risk. Use the checklists and references provided to structure procurement, pilot and cutover for a measurable outcome.
