Comparing Polyglot and SimpleLocalize for small developer teams. See how a CLI-first detection tool compares to a lightweight, affordable translation management system.
SimpleLocalize is a lightweight translation management system focused on simplicity and affordability. Paid plans start at €12/month, making it one of the cheaper dashboard-based TMS options. Polyglot is a CLI-first tool that finds hardcoded strings, translates with LLMs, and previews locally — starting at $0 for scanning.
The key difference: SimpleLocalize is an affordable dashboard TMS. Polyglot isn't a TMS — it's a detection and translation tool that starts in your codebase. Scan, plan, wrap and preview run on your machine; generated translations are reviewed in the Polyglot dashboard (automatic approval is off).
| Feature | Polyglot | SimpleLocalize |

| Hardcoded-string detection (AST-based) | ✓Yes | ✕No |
| AI/LLM translation | ✓Yes, built-in | ✓Yes (OpenAI, Anthropic, Gemini, DeepL and more) |
| Output formats | JSON, YAML, ARB, iOS .strings, Android XML | JSON, others |
| Local preview | ✓Yes (polyglot preview) | ✕No |
| IDE integration | VS Code extension (inline diagnostics) | ✕No |
| CI/CD integration | ✓Yes (GitHub Action) | ✓Yes (CLI) |
| CLI support | Primary interface | ✓Yes |
| Web dashboard | ✓Yes (translation review) | ✓Yes (clean, simple) |
| Free tier | Free local scanning, 500 source strings (lifetime) | ✓Yes (limited) |
| Starting price | $0 | €12/mo (Developer) |
| Translation memory | ✓Yes | ✓Yes (all plans) |
| Glossary support | ✓Yes | ✓Yes |
| CDN delivery | ✕No | ✓Yes |
| Hosting translations | No (files in your repo) | ✓Yes (hosted + CDN) |
SimpleLocalize is one of the cheaper TMS platforms on the market. At €12/month for the Developer plan, it costs far less than Crowdin ($59), Lokalise ($149), or Phrase Strings ($525/month billed annually). For budget-conscious teams that need a dashboard, it's hard to beat.
The name is accurate — SimpleLocalize is intentionally simple. The dashboard is clean, the API is straightforward, and there's minimal cognitive overhead. You won't spend a week learning the platform.
SimpleLocalize offers auto-translation with OpenAI, Anthropic, Gemini, DeepL and other providers, plus translation memory on every plan.
SimpleLocalize can host your translations and serve them via CDN, which is useful for mobile apps or sites that need translation updates without code deploys.
SimpleLocalize's CLI can push and pull translation files, making it easy to sync between your repo and the dashboard. The developer experience is better than many larger competitors.
Polyglot finds hardcoded strings in your source code with tree-sitter AST parsing. Detection covers Next.js, Astro, SvelteKit, Vue, Angular, React Native and Flutter; runtime support varies by setup, and Next.js App Router with next-intl is the best-tested path. SimpleLocalize manages strings you've already extracted, so finding and wrapping them is up to you. A VS Code extension surfaces those findings inline as you write code.
Polyglot uses a fine-tuned translation engine and sends component context, glossary terms, and translation memory alongside each string. It scored 4.96/5 across 49 languages on our June 2026 pipeline, AI-judged — reproducible benchmark.
Polyglot writes JSON, YAML, ARB, iOS .strings, and Android XML, so the same workflow can cover web frontends and mobile catalogs.
polyglot preview shows translations in your app before deploying. SimpleLocalize focuses on the dashboard and CDN delivery.

SimpleLocalize wins on dashboard price, and it has a free plan too. Polyglot covers a different step: finding and wrapping hardcoded strings, which SimpleLocalize doesn't do. See SimpleLocalize pricing for current limits.
