Interoperability standards are the technical foundation of data portability. Open standards define data formats that multiple tools can read and write, making migration between platforms possible without data loss. The business that evaluates tools on interoperability criteria before adoption pays a lower exit cost if the product enshittifies than the business that evaluates on features alone.
What Do Open Standards Look Like in Practice for Data Portability
A tool that stores data in open, documented formats can be migrated from. CSV exports of operational data, JSON exports of audit histories, standard database dumps: these are interoperability in practice. A tool that stores data in proprietary formats accessible only through its own export mechanism is a lock-in architecture.
The distinction is not always visible before adoption. It becomes visible when you try to leave. Evaluating interoperability before adoption means asking: what format does this tool export data in? Can I import that format into a competing tool? Can I access my data directly, not just through an export function the platform controls?
Which Tools Support Portability and Which Build Lock-In by Design
| Attribute | Open Source Tools | Proprietary SaaS |
|---|---|---|
| Codebase | Inspectable: anyone can read it | Closed: governed entirely by the vendor |
| Data schema | Documented: you know how your data is stored | Proprietary: format defined and controlled by vendor |
| Export format | Open standards by default (CSV, JSON, SQL) | Varies: often incomplete or vendor-specific |
| Portability | Built into the architecture by design | Designed against: portability reduces switching cost |
| Switching cost | Low: data migrates with you | High by design: accumulated data is the lock-in mechanism |
| Lock-in mechanism | None: governance structure removes the incentive | Central to the business model and revenue strategy |
Open source tools built on standard protocols generally support portability because they have to. The codebase is inspectable, the database schema is documented, and the community that maintains the tool has an interest in open standards that the community driving proprietary SaaS does not share.
Proprietary SaaS tools vary. Some offer meaningful data exports that cover the data the business actually needs to migrate. Others offer exports that cover the data they are comfortable with you taking while retaining the data that is most valuable for lock-in.
What Does a Real Migration Between Platforms Actually Cost
A migration from a platform with good interoperability costs time: the time to export, transform, import, and validate data. A migration from a platform with poor interoperability costs that plus the loss of data that cannot be exported and the rebuilding of baselines from scratch.
The second cost is the one that lock-in pricing depends on. The platform that keeps your most valuable historical data in a format you cannot meaningfully export has made that data a hostage. The ransom is continued subscription payments at whatever price the platform decides to set.
Frequently Asked Questions
What data formats should you look for when evaluating SaaS portability?
When evaluating a SaaS tool before adoption, check whether it exports data in open, standard formats:
- CSV for tabular operational data: rows, columns, importable anywhere
- JSON for structured records with relationships preserved
- SQLite or PostgreSQL dumps for complex datasets where schema matters
- CalDAV for calendar and scheduling data
- IMAP for email archives
Proprietary formats accessible only through the platform's own export function are lock-in architectures regardless of what the sales team tells you about data ownership.
How long does it actually take to migrate from one SaaS platform to another?
A migration with good data portability takes days to weeks. A migration with poor portability takes months and involves rebuilding baselines from scratch. the step-by-step migration guide with a realistic time estimate for each phase.
What is the difference between data export and data portability?
Data export is the platform giving you a file containing some of your data. Data portability is the condition under which that file can be imported into a competing service without loss of functionality. Most platforms offer data export. Meaningful portability, where exported data retains its analytical value in another system, requires open standard formats.
