Unbabel Review 2025: Pricing, Features & Alternatives

Overview

Unbabel is a LangOps (Language Operations) platform that combines always-on AI (machine translation + quality estimation) with optional human post‑editing to scale translations while controlling cost, speed, and quality. Core capabilities identified on public pages include machine translation with human-in-the-loop workflows, AI Quality Estimation (QE) to score translations in real time, customizable workflows by market/content type, integrations into existing tooling (CRMs, help desks), the Polyglot editor, and multiple APIs (Language OS / Unbabel Qi / Quality Intelligence). Public documentation and developer resources (developers.unbabel.com) describe Language OS APIs, Unbabel Qi API, and Quality Intelligence API with tutorials. The site contains customer stories, integration listings (Zendesk, Intercom, Freshdesk, Wix Answers, Oracle B2C Service, Helpshift, Kustomer, etc.), a help/knowledge base (help.unbabel.com), and product news (e.g., TowerLLM and Quality Intelligence API announcements). The company about page states Unbabel was founded in Lisbon by Vasco Pedro and co‑founders João Graça, Sofia Pessanha, Bruno Silva, and Hugo Silva (founded ~2013 per public sources). The public pricing page produced a 504 at the time of review, so no stable public pricing tiers were observed; site content and an article about translation pricing explain per-word, hourly, per-page, and project fee drivers, and discuss how QE and MT influence cost. Recommended next steps from the review: retry the pricing page later, or contact sales / request a demo for a custom quote; for technical evaluation, extract API endpoints or QE API docs from developers.unbabel.com.
