How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Lokalise suits product teams that ship mobile and web apps quickly, with AI translations, a centralized workspace, and integrations with dev tools.
- Crowdin suits teams that want a huge integration library and community translation, with 600 plus integrations.
- Phrase suits enterprises running both software strings and long form content, though its suite pricing differs sharply from its freelancer plan.
- Smartling suits enterprises with big content volume and complex workflows, with a free Core plan and custom Enterprise pricing.

The best app localization providers
#1Lokalise
Best for: Fast shipping product teams4.7/5 on
G2 (765 reviews, checked Oct 2026)
Visit lokalise.com
Starting price$144 per month
Free planYes
Lokalise is the pick for product teams that ship mobile and web apps quickly, offering software and mobile app localization with centralized workflow management, AI translations, and integrations with dev tools. Explorer starts at $144 per month in most listings, with $149 per month reported in some sources, while Growth runs $379 to $439 per month depending on billing, and Advanced reaches about $11,988 per year, so the entry price is a floor, not the scenario total.
The trade off is speed against scaling cost. Lokalise ships fast with strong integrations, but seats, processed words, and overages push real bills well above entry prices. Lokalise fits product teams that ship often and need dev tool integrations.
What we like- AI translations
- Centralized workspace
- Integrations with GitHub, Jira, Figma, and mobile SDKs
- 24/7 chat and email support
- Fast setup in hours to days
Watch out for- Entry price reports conflict at $144 and $149 per month
- Growth at $379 to $439 per month pushes bills up fast
- Advanced seats and overages add cost
- Enterprise is custom quote
#2Crowdin
Best for: Integrations and community4.4/5 on
G2 (749 reviews, checked Oct 2026)
Visit crowdin.com
Starting price$59 per month
Free planYes
Crowdin is the pick for teams that want a huge integration library and community translation, with 600 plus tools including GitHub, GitLab, and Figma, plus community support, automation, and security features. Pro starts at $59 per month in most listings, with $50 per month reported in some sources, while Team runs $150 to $179 per month for larger projects, and enterprise controls for 30 million plus words need a custom quote.
The trade off is integration breadth against metering complexity. Crowdin connects to nearly everything, but its word and manager seat metering makes bills harder to predict. Crowdin fits teams that want community translation and the widest integration library.
What we like- 600 plus integrations
- Community translation support
- Automation and security features
- Good for large scale collaborative projects
- Free tier for starting out
Watch out for- Entry price reports conflict at $50 and $59 per month
- Team at $150 to $179 per month for larger projects
- Word based metering pushes bills up
- Enterprise controls need custom quote
#3Phrase
Best for: Software plus content4.5/5 on
G2 (1,346 reviews, checked Oct 2026)
Visit phrase.com
Starting price$27 per month
Free planNo
Phrase is the pick for enterprises running both software strings and long form content, with developer tools, API and CLI support, translation memory, and Phrase Analytics. Its Freelancer plan starts at $27 per month with annual billing, but its Software UI/UX suite costs $525 per month, and Team runs $14,940 per year, so the headline price and the suite price describe very different products.
The trade off is breadth against price confusion. Phrase covers software and content in one platform, but its pricing tiers differ so sharply that buyers must confirm which suite they need. Phrase fits enterprises that run both software strings and long form content and can justify suite pricing.
What we like- Covers both software strings and long form content
- Developer tools with API and CLI
- Translation memory
- Phrase Analytics
- Strong for enterprises running both content types
Watch out for- Freelancer at $27 per month versus Software UI/UX suite at $525 per month, a sharp gap
- Every user is a seat
- Team at $14,940 per year
- Business and Enterprise custom quote
- 14 day trial only
#4Transifex
Best for: Continuous localization4.2/5 on

Visit transifex.com
Starting price$139 per month
Free planNo
Transifex is the pick for SaaS teams running continuous localization through CI/CD, with automation that keeps translations flowing with frequent releases. Starter starts at $139 per month with annual billing in most listings, with $135 per month reported in some sources, and larger volumes at 1.8 million hosted words require a sales contact, while Enterprise plus is custom quote.
The trade off is CI/CD strength against volume pricing. Transifex automates continuous localization well, but its word based pricing pushes larger teams to sales. Transifex fits SaaS teams with frequent releases that need continuous localization.
What we like- SaaS teams running continuous localization through CI/CD
- Strong automation
- Good for software teams with frequent releases
- Free trial for evaluation
Watch out for- Entry price reports conflict at $135 and $139 per month
- Starter at 100,000 hosted words costs $2,580 per year annually
- Larger volumes need sales contact
- Enterprise plus custom quote
Starting price$0
Free planYes
Smartling is the enterprise pick for large organizations with big content volume and complex workflows, offering visual context for translators within page layouts, quality assurance tools, and enterprise APIs and CMS integrations. Its Core plan costs $0 for limited document work, while a comparable product workflow needs an Enterprise quote, and usage based pricing is reported at $0.0075 per unit in some listings.
The trade off is enterprise power against sales led pricing. Smartling handles the largest, most complex localization programs, but its real price is only available through sales. Smartling fits enterprises with big content volume and complex workflows.
What we like- Free Core plan for limited document work
- Visual context for translators within page layouts
- Quality assurance tools
- Enterprise APIs and CMS integrations
- Account management
Watch out for- Comparable product workflow needs Enterprise quote
- Setup takes days to weeks
- Usage based pricing at $0.0075 per unit in some listings
- Overkill for small teams
Starting priceFree
Free planYes
Weblate is the open source pick for teams that want open source code and self hosting, with the self hosted version free and a gratis hosted tier for libre projects. Hosted Premium Cloud starts from 47 euros per month in most listings, though some comparisons report 470 euros per year, so check the current pricing page before committing. It suits teams that value data control and open code over managed convenience.
The trade off is control against convenience. Weblate gives you full control and free self hosting, but self hosting needs technical skill and support is community led. Weblate fits teams that want open source localization and can self host.
What we like- Open source code and self hosting
- Self hosted version free
- Gratis hosted tier for libre projects
- Hosted Premium Cloud from 47 euros per month
- Full data control
Watch out for- Self hosting needs technical skill
- Hosted pricing reports conflict at 47 and 470 euros per year in different comparisons
- Support is community led for self hosted
- Fewer enterprise workflow features
#7POEditor
Best for: Simple cheap string management4.5/5 on
G2 (93 reviews, checked Oct 2026)
Visit poeditor.com
Starting price$17 per month
Free planYes
POEditor is the simple, cheap pick for small teams that want straightforward string management without enterprise complexity, starting at $17 per month billed annually, with a free tier covering 1,000 strings. It suits small teams that need to manage app strings in several languages without learning a large platform.
The trade off is simplicity against scale. POEditor is easy and cheap for small projects, but larger projects move to Plus at $51 or Premium at $136 per month, and its workflow features are thinner than Lokalise. POEditor fits small teams that want simple, cheap string management.
What we like- Simple and cheap string management
- Start at $17 per month billed annually
- Free tier with 1,000 strings
- Easy for small teams
- Fast setup
Watch out for- Fewer advanced workflow features than Lokalise or Smartling
- String based metering pushes larger projects to Plus at $51 or Premium at $136 per month
- Fewer integrations than Crowdin
Starting price$66 per month
Free planYes
Tolgee is the developer pick for teams that want in context editing inside the live app, letting translators and developers see translations where users actually see them, which catches layout and context errors early. Translate starts at $66 per month billed annually in most listings, with 133 euros per month reported in some comparisons, so check the current pricing page before committing, and its free tier covers 30,000 words and 3 seats.
The trade off is context accuracy against integration breadth. Tolgee catches context errors better than any tool here, but its integration library is smaller than Crowdin. Tolgee fits developer led teams that value in context editing.
What we like- In context editing inside the live app
- Developers see translations where users see them
- Free tier with 30,000 words and 3 seats
- Good for developer led teams
Watch out for- Entry price reports conflict at $66 per month and 133 euros per month in different comparisons
- Larger plans at $99 to $166 per month
- Smaller integration library than Crowdin
How we chose
We compared published feature lists and pricing from 2026, favoring tools with distinct strengths: the fastest shipping, the widest integrations, the broadest software plus content coverage, the best continuous localization, the largest enterprise volume, the best open source option, the simplest cheap management, and the best in context editing. We recorded prices as reported and flagged conflicts for Lokalise, Crowdin, Phrase, Transifex, Weblate, and Tolgee. We favored tools with a current release and an active product team user base, and we stressed that entry prices are floors, not scenario totals, since seats, words, and keys drive real bills.
How to choose an app localization provider
Start with your team type: fast shipping product teams point to Lokalise, community projects point to Crowdin, software plus content enterprises point to Phrase, CI/CD SaaS teams point to Transifex, and large enterprises point to Smartling. Next, price your actual project: count source keys, target languages, seats, and hosted words, then compare scenario totals, not headline prices, since a $27 freelancer plan and a $525 suite plan describe different products. Then check integrations with your stack, including Git, Figma, and mobile SDKs, and test in context editing if layout errors are a recurring problem. Finally, confirm whether self hosting matters: Weblate suits teams that need data control, while managed platforms suit teams that want to avoid infrastructure work.

How much does app localization software cost?
Entry prices run from free for Weblate self hosted and Smartling Core to $17 per month for POEditor and $144 per month for Lokalise, but scenario totals with seats, words, and overages run much higher, so price your actual project.

Check your source key count, target languages, seat count, hosted words, integrations with Git and Figma, in context editing, and whether enterprise features need a custom quote.
