Smartling - 2026 Pricing, Features, Reviews & Alternatives

Smartling is the AI Translation Platform that helps companies grow globally, faster.

Recognized as the #1 translation management system (TMS), #1 website translation tool, and leading localization services provider (LSP) by G2 users and CSA Research, Smartling is built on a simple belief: translation should be always-on AI infrastructure, not a project-based afterthought. With 12 billion words translated annually, Smartling delivers an average turnaround of 1.3 days—10x faster than traditional LSP approaches—while reducing cost per word by up to 60%.

What sets Smartling apart is its fully integrated TMS and language services on a single open platform. Smartling tests 70+ AI models monthly and auto-routes content to the best model for each use case—with built-in governance, audit trails, and quality controls that protect your brand at scale. Whether you need AI-only speed, AI + human post-editing, or full human translation, Smartling adapts to your quality and risk requirements.

Smartling's Global Delivery Network (GDN) enables companies to translate their entire website without touching a line of code. A proxy-based solution that sits between users and your site, GDN automatically detects, translates, and delivers localized content in real time—so you can go multilingual fast, regardless of your underlying tech stack.

Here's what makes Smartling stand out:

Translation done your way. The platform provides the software, integrations, and services necessary for a successful translation program—all in one place. Whether it's our TMS, expert linguists, or integration with top-tier AI and machine translation models, we help you build a translation approach tailored to your specific needs—with full flexibility to bring your own models, data, and linguists.

Work in the tools you already use. No more switching between screens—start, track, and complete translations within your preferred content platforms. Smartling offers 50+ integrations with popular CMS, commerce, and support tools, plus a customizable API for everything else.

Provable quality at every step. Smartling's LQA Agent delivers 98+ MQM scores with human-in-the-loop review and 96+ MQM fully automated—removing up to two-thirds of content from the human review pipeline without sacrificing accuracy. Every translation includes a full audit trail of models, versions, and human edits.

Smartling is trusted by hundreds of global brands, including IHG Hotels & Resorts, Shopify, Pinterest, State Farm, British Airways, OpenAI, and Lyft.
