Website & App Maintenance Services in Thailand to Keep Your Software Fast, Secure, and Always Online
TrueDev is a Bangkok-based team providing professional website and app maintenance in Thailand, keeping your digital products fast, secure, and online for businesses across Bangkok and worldwide. We handle everything from security patching, uptime monitoring, and bug fixes to dependency upgrades, performance tuning, and small feature work β so your website or mobile app keeps earning its keep instead of quietly breaking.
Launching software is only the beginning. Frameworks change, browsers update, libraries develop vulnerabilities, and traffic patterns shift. Our proactive monitoring catches issues before your customers do, and our rapid response means a real engineer is already looking when something goes wrong. We have been building software since 1997, and we apply that same engineering discipline to ongoing care, not just new builds.
Whether you need a maintenance retainer for a site we built, or want to hire a maintenance agency in Thailand to take over an inherited codebase, we make support predictable. You get transparent fixed pricing, work in your timezone, an English-speaking team, and full ownership of your code and data β no offshore middlemen and no lock-in.
What Is Support & Maintenance?
Think of your website like a car. You wouldn't drive it for years without an oil change, tire rotation, or safety check. Support & maintenance is your website's service plan β keeping everything running smoothly, securely, and up to date.
Without Maintenance
The Risk
Outdated dependencies with known exploits. Slow load times driving customers away. Unexpected crashes at the worst possible moment. No backups when disaster strikes. Mounting technical debt making every fix harder.
With TrueDev Support
Peace of Mind
Every dependency patched and up to date. Performance optimized and monitored 24/7. Issues caught and resolved before users notice. Automated backups with tested recovery plans. Clean, maintainable code that evolves with your business.
Launching a website is just the beginning. Keeping it secure, fast, and reliable is what separates businesses that thrive from those that fall behind.
Why Maintenance Can't Wait
The cost of neglecting your application compounds over time. These are the risks of going without a maintenance plan.
Security Vulnerabilities
Unpatched dependencies are the #1 attack vector. Every day without updates is a day your application is exposed to known exploits and data breaches.
Performance Decay
Databases grow, caches expire, and code accumulates bloat. Without regular optimization, your once-fast application slows to a crawl.
Downtime Cost
Every minute of downtime costs revenue and trust. For e-commerce sites, even 30 minutes of unplanned downtime can mean thousands in lost sales.
Technology Debt
Frameworks evolve, APIs deprecate, and browsers update. Falling behind means increasingly expensive fixes and eventual forced rewrites.

Your Application Never Sleeps β Neither Do We
Round-the-clock monitoring means we catch issues before your users do. From security threats to performance dips, we're watching so you don't have to.

Why Businesses Choose TrueDev for Website & App Maintenance
Companies hire us to maintain their websites and apps because we treat uptime as a promise, not a hope. Since 1997 we have shipped and supported real software, so we know which dependency upgrades are safe, how to read an error log at 2am, and how to fix the root cause instead of restarting the server and praying. With a Bangkok-based team working in your timezone, you reach a person who actually knows your stack β not a ticket queue.
Pricing is transparent and predictable. Before any work begins you get a clear maintenance plan and a fixed estimate, with most retainers starting in the low thousands of US dollars per month depending on scope and response times. There are no surprise invoices and no offshore middlemen marking up the work. You own everything β the code, the credentials, the infrastructure, and the data β and we document it so you are never held hostage.
We are also serious about security and compliance. We keep software patched, monitor for vulnerabilities, and build with PDPA and GDPR in mind, which matters when you handle customer data in Thailand and abroad. Above all, we are outcome-focused: a fast, stable, secure product that supports your business, backed by an English-speaking team you can actually talk to.
