Best Translation & Localization Software
Scale to global markets without drowning in spreadsheets of translations
TL;DR
Lokalise is best for developer teams wanting modern UX and great integrations. Phrase (formerly Memsource) leads for enterprise translation workflows. Crowdin offers excellent value for open source and growing teams. For simple projects, Google Translate API works. For serious localization, invest in proper tools—they pay for themselves in efficiency.
Translation software has evolved from simple text replacement to sophisticated localization platforms. Managing translations in spreadsheets works until it doesn't—versions get confused, context is lost, developers wait on translators, and releases slip. Modern localization platforms streamline the workflow, preserve context, and integrate with your development process. Here's how to choose.
What is Translation/Localization Software?
Translation Management Systems (TMS) centralize your multilingual content workflow. They store translations, provide context for translators, integrate with your codebase and CMS, handle version control, and often include translation memory (reusing past translations). Localization goes beyond words to adapt content for cultural and regional differences.
Why Localization Tools Matter
Global markets require local experiences—42% of consumers never buy in foreign languages. But managing translations manually creates bottlenecks: developers copying strings to spreadsheets, translators lacking context, QA missing coverage, releases delayed. Good tools automate the tedious parts and let everyone focus on quality translations.

Key Factors to Consider
- How many languages and how much content? Pricing scales with both
- Who translates? In-house, freelance, or agency affects workflow needs
- What's your stack? Check integrations with your frameworks and CMS
- How technical are your translators? Interface complexity varies
- Do you need machine translation assistance or human-only workflows?

Crowdin
Flexible localization with excellent free tier for open source
Best for: Open source projects and teams wanting value and flexibility
Pros
- Free for open source
- Good feature set
- Active community
- Reasonable pricing
Cons
- Interface less polished
- Some integrations need work
- Support responsiveness varies
- Advanced features require upgrades
Common Mistakes to Avoid
- Starting localization without string externalization—fix your code first
- Using spreadsheets until it becomes painful—migrate to proper tools early
- Treating translation as word replacement—localization is deeper
- Launching all languages at once—start with 1-2 and learn
- Skipping translation QA—broken translations are worse than no translation
Expert Tips
- Externalize strings from day one—retrofitting is painful
- Provide context: screenshots, descriptions, character limits help translators
- Use translation memory across projects to maintain consistency
- Machine translation for first drafts, human review for quality
- Test with pseudo-localization before real translations catch layout issues

Lokalise is the best choice for developer-centric teams wanting modern tooling. Phrase serves enterprise translation operations with sophisticated workflows. Crowdin offers excellent value, especially for open source. Invest in proper localization tools early—the efficiency gains compound as you add languages and content.
Frequently Asked Questions
Can I just use Google Translate?
For understanding content, yes. For production content, no—quality varies, it misses context, and you need workflows for review and updates. Use machine translation as a starting point for human refinement, not as the final product.
How much does translation cost per word?
Professional human translation: $0.08-$0.25 per word depending on language and complexity. Machine translation post-editing: $0.03-$0.10. Community translation: free but slower. Your TMS cost is separate from actual translation services.
When should I start localizing my product?
After product-market fit in your primary market, when you see organic international interest. Start with 1-2 strategic languages to learn the process before scaling. Ensure your codebase is localization-ready first.
