Unlike systems that lock you into specific translation providers, XTM Cloud allows you to work with your preferred language service providers (LSPs) while keeping control of your translation assets and memory.

The platform’s AI capabilities accelerate human translation rather than replace it. XTM AI SmartContext fine-tunes large language model (LLM) based translation outputs with fuzzy matches from translation memory for improved consistency.

Linguists and reviewers can see exactly how strings appear with integrated real-time visual context from Rigi (more on this tool later). Using this platform in conjunction with XTM Cloud reduces errors and guesswork and speeds up your QA.

Use cases include companies like Ariel, where AI-powered workflows in XTM Cloud reduce human translation by 31% and double machine translation output. All while improving quality and cutting costs.

XTM Cloud is specifically built to help you manage complex software localization at scale. Research shows that AI tools like those baked into XTM Cloud reduce time to market by almost 30%.

Phrase: Enterprise localization with string-key workflows

Source: G2

Localization shouldn’t be an afterthought. With Phrase, it becomes part of your development pipeline.

Rather than juggling raw text, the tool stores translated content with unique identifiers (like “welcome_message” or “checkout_button”). So it’s easy to ensure accurate translations across languages.

Phrase hooks directly into repositories like GitHub and GitLab, meaning you can handle translations alongside code changes.

That parallel workflow? You get to launch in multiple new markets at once.

Phrase is built for speed. If your team needs strict vendor management or approval workflows, the setup may feel lightweight.

This simple software is a strong fit for engineer-led teams where localization must move as fast as code. If your org runs on layered audit trails and regulatory oversight, double-check that it can help you tick those boxes.

Smartling: Automated content detection for web and mobile apps

Source: G2

Smartling’s Global Delivery Network (GDN) automatically captures text updates and sends them for translation right away. The result? It cuts out the “string hunting” process that slows down app localization.

The platform uses a mix of AI translation for high-volume content and professional translators for customer-facing elements. It’s designed around managed workflows, where tasks move through set stages from translation to publishing.

This setup keeps things moving quickly. If you want more freedom to customize workflows or manage translation steps yourself, you might find Smartling limiting.

Smartling’s automatic content detection is designed to save time. Just be aware you’re trading some workflow flexibility for convenience.

Developer-friendly and API-first tools

Developer-friendly and API-first tools put the power directly in your technical team’s hands.

These solutions integrate smoothly with your existing development process, letting engineers manage translations through code rather than jumping between different platforms. They’re ideal for teams that prefer automation over manual file handling.

Rigi: Visual previews without source code access

Rigi by XTM is a robust software localization platform showing dynamic visual previews of translated software UI.

It shows translators and reviewers exactly where and how text will appear in your interface (including space constraints and surrounding elements) instead of sending them isolated strings.

Eliminate guesswork with visual localization

See how Rigi helps translators work faster and more accurately by showing exactly how strings appear in the user interface. In real time.

Rigi’s visual approach streamlines the development cycle. When translators instantly see a string’s purpose, they can make smarter decisions about length, terminology, and tone.

All without bombarding your team with questions about context.

Rigi fits right into your existing development workflow thanks to its API for automated file handling. Plus connections to UI testing frameworks that capture real-time HTML previews as your interface changes.

With Rigi’s visual approach, you’ll finally bridge the gap between development and translation. Meaning faster releases and even better products for global markets.

Lokalise: When design and development need to speak the same language

Source: Lokalise

Lokalise keeps translations in sync with your development cycle so localization doesn’t lag behind your code updates.

The API and CLI tools reduce manual work by automating file handling. Design software plugins let designers flag text for translation from the mockup phase.

Mobile app developers can update translations without submitting new builds to app stores using the over-the-air SDK. This means you can fix translation errors without waiting for app review processes.

Lokalise primarily focuses on web and mobile apps. If you need to localize gaming UI or desktop software, another tool may be a better fit.

Lokalise provides a collaborative platform for teams that span product, development, and localization departments. How well the tool fits depends on your needs.

Crowdin: Continuous localization at development speed

Source: Crowdin

Crowdin bakes localization into your development pipeline. So you can launch in different languages the moment your product goes live.

Developers can automate the entire process using the CLI, API, or webhooks, syncing directly with your code repositories. So your team doesn’t have to handle localization files manually.

In Crowdin, translators see screenshots and visual context that show how and where each string appears.

The trade-off? A steep learning curve — especially for smaller teams.

You might spend more time getting your bearings than completing translations at the start. And because it’s string-based, you’ll want to ensure careful planning to maintain consistency across your projects.

In sum, Crowdin delivers continuous localization for development-focused teams. Just be ready to spend a little time finding your feet first.

Transifex: Real-time translation infrastructure

Transifex — recently acquired by XTM — helps you translate your software while your team keeps building. The platform connects to your code repositories so translators can work on the latest content without holding up your release schedule.

Need to fix a mistranslation? Push it live instantly with over-the-air updates instead of waiting for your next deployment.

The platform combines AI-powered translation to handle high volumes with visual context tools that show translators exactly where text appears in your interface. This blend of automation and context awareness helps maintain quality while keeping costs in check.

For developers, Transifex offers API, SDK, and CLI options that fit neatly into the existing CI pipeline. Making translations just another part of your regular workflow.

Open-source and budget-conscious options

Not every project requires an enterprise-grade localization platform with all the bells and whistles.

If you’re working with limited resources or need a simple solution for smaller projects, these open-source and budget-friendly options deliver solid functionality without the enterprise price tag.

Poedit: Local translation editor with syntax validation

Source: L10n Software

Poedit is a no-frills translation editor for developers and translators working with heavily code-based formats. Like GetText, XLIFF, JSON, and Flutter.

It catches common issues like incorrect plural forms, missing tokens, and syntax errors. Use its built-in quality check to avoid translation bugs that often sneak into software releases.

There’s a one-time payment option that independent developers and small teams will find cost-effective.

While Poedit works well for local translation tasks, it lacks team coordination features and integrations with development pipelines. Making it less practical for larger collabs.

With Poedit, you get desktop-based translation with strong validation checks. Minus the team collaboration and automation features that cloud-based platforms offer.

Weblate: Git-native translation for self-hosted control

Source: G2

Weblate is a self-hosted localization platform designed for teams that want more control over their translation process. It integrates tightly with your version control system, allowing translators to work directly with your code in real time without disrupting the development flow.

Weblate gives you the option to host everything on your own infrastructure. It supports continuous translation, so you can push source string updates to your repository without manual steps.

Its web interface supports collaborative translation. The platform has built-in TM, glossaries, and automated quality checks to ensure consistency for global audiences.

Weblate’s developer-friendly localization platform supports projects seeking full control through self-hosting. The technical setup may better suit teams with in-house engineering resources.

How to choose the right software localization tool

Research shows that 65% of companies report a three times ROI or more when localizing content. That’s why choosing the right tool is crucial — it can directly impact your efficiency and bottom line.

Along with basic capabilities and pricing, consider these five critical factors. They’ll help you determine whether a tool fits your development environment and business goals.

1. Common localization workflow needs and team structures

Pick a tool that matches your team’s size and structure, or you’ll pay for it later. Enterprise platforms overwhelm small teams with unnecessary complexity, while basic tools crumble under the weight of large organizations.

When evaluating options, ask yourself:

• How many developers vs. translators do you have? Developer-heavy teams need strong CLI and API features, while translator-heavy teams need better interfaces and context tools.
• How often do you release? Weekly updates demand continuous localization that syncs with your repositories. Monthly releases can manage with manual processes.
• Where is everyone located? Teams spread across time zones need cloud solutions with granular permissions. Co-located teams can use simpler tools.
• Who’s managing localization? If it’s your developers, look for code-centric tools. If it’s marketing, prioritize user-friendly interfaces.
  
  

Don’t swim against the current. Choose a tool that fits your existing workflow.

If you live in GitHub, get a tool with GitHub integration. If your team runs on Jenkins pipelines, ensure your localization platform plays nice with your CI/CD setup.

2. Integration with your existing tech stack

Your tech stack forms an ecosystem where tools need to work together. When your localization platform sits disconnected from this ecosystem, you create a translation island that drains productivity.

Before committing to any platform, verify that it connects directly with:

• Your code repositories (GitHub, GitLab, Bitbucket): Does it automatically detect new strings when developers commit code?

• Your CMS (WordPress, Contentful, Adobe): Can it pull content directly without manual exports that go stale immediately?

• Your design tools (Figma, Sketch): Can translators see visual context without developers creating screenshots?

• Your deployment pipeline: Will translations automatically flow into builds, or will someone need to copy files manually?

Each missing integration turns into a repetitive manual task. Even something as routine as a 10-minute export-import step can quietly drain hours. One study showed that automating five simple tasks saves five hours a month.

Without that kind of automation, teams waste valuable time. Worse still? Manual handoffs can cause errors, leaving global users seeing outdated or missing translations.

3. Scalability and automation

The localization tool that efficiently handles your current app might become your biggest constraint next year. When your string count jumps from hundreds to thousands, or your language count triples, inadequate tools create painful technical debt.

When evaluating scalability, ask about:

• Future costs: What happens when your app has 3x more text? Some per-word pricing models become expensive at scale.

• Duplicate strings: Can the system automatically detect and flag duplicate strings? If not, you could be paying to translate the same sentence. That adds up quickly.

• High volumes: Does it offer APIs for batch operations when your string count hits 10,000+? Manually processing these volumes is a huge time sink.

• Multi-repo management: Can it handle automatic string extraction from multiple repositories and branches without manual work?

• Language-specific QA: Does it provide automated QA for challenging language pairs (like German text expansion or right-to-left languages)?

Investing in scalable automation now prevents the hidden costs of manual workarounds and emergency fixes as your localization needs grow.

4. Collaboration, quality control, and review flows

Poor collaboration between developers and translators leads directly to poor-quality translations. When translators can’t ask questions about context, they make assumptions. When developers can’t easily review translations, errors slip through.

Evaluate your localization platform’s collaboration capabilities by checking for:

• Team communication: Does it integrate with your messaging platforms (Slack, Teams, Discord)? If not, you risk missing important messages.

• String annotation: Can developers highlight specific strings? It’s the easiest way to tell translators when strings need special attention.

• In-platform comments: Do translators have a direct way to ask about ambiguous strings? Email can slow things down.

• Visual context: Can reviewers see strings in context? Without it, reviewers might make approvals that break layouts.

• Edit tracking: Does the platform track edit history? Seeing who changed what avoids awkward conversations.

The review process is particularly critical for software localization. Look for tools that support staged reviews (translation → review → final approval) with appropriate permissions for each role.

Automate quality safeguards where possible. Check if the platform can automatically detect missing variables, HTML tags, or pluralization issues that would break your application when deployed.

5. Support and onboarding

Even the most powerful localization tool becomes useless if your team can’t figure out how to use it. Implementation challenges can delay your global launches by weeks or months.

When evaluating support quality, look beyond the sales promises to:

• Test the support team’s responsiveness before purchasing: How quickly do they answer pre-sales technical questions?

• Ask for specifics about onboarding: Do they have self-service videos or offer personalized training sessions?

• Request access to documentation: Is it comprehensive, up-to-date, and includes developer-specific sections?

• Check if they offer implementation support for your tech stack: Have they helped teams using your frameworks before?

• Ask about support channels: Are they limited to email tickets, or do they offer real-time chat for urgent issues?

The quality of technical documentation matters particularly for developer tools. Look for clear API references, sample code for common integrations, and troubleshooting guides specific to your development environment.
