Application maintenance and support services that prevent surprises
We keep web and mobile applications secure, fast and up to date with proactive monitoring, regular updates, prompt fixes and steady improvements, whoever originally built them.
ZedBlu provides application maintenance and support services for web apps, mobile apps, APIs and internal systems, whether we built them or another team did. We monitor, patch, fix and improve your software under a monthly plan, so it stays reliable and secure long after launch.
Software does not stand still even when your features do. Operating systems update, browsers change, libraries publish security fixes, app store rules tighten and cloud services retire old versions, so without regular care small issues compound into outages, security incidents or a forced rebuild.
Our software maintenance services begin with an onboarding audit of your code, infrastructure and documentation. We understand the system before we take responsibility for it, and you get a clear list of risks and priorities from the first month.
What our Application Maintenance & Support team delivers
Bug fixing and incident response
We triage reported issues by severity, reproduce them, fix the root cause and release through a tested pipeline. Critical incidents are handled first under the response times in your plan, followed by a short write-up explaining what happened and how a repeat is prevented.
Security patching and dependency updates
Regular updates to frameworks, libraries, server packages and container images, backed by vulnerability scanning that catches known issues. Every update is tested in staging before production, so patches are verified before they reach your users.
Monitoring and performance tuning
Uptime checks, error tracking, performance monitoring and log alerts tell us about problems before users report them. Each month we review trends, tune slow queries and pages, and plan capacity ahead of expected traffic growth.
Mobile app maintenance
App maintenance and support for iOS and Android: compatibility with each new OS release, SDK and policy updates required by Apple and Google, crash fixes driven by production reports, and store listing updates that keep your app in line with store requirements.
Website maintenance
Website maintenance services covering CMS and plugin updates, backups, uptime and speed monitoring, form and integration checks, content updates and small design changes, giving your marketing team a dependable partner for the routine web tasks that pile up.
Enhancements and project takeover
Inherited an application from a freelancer or agency that is no longer available? We take over existing software projects through a structured handover: code audit, documentation, environment setup and a stabilization plan, then keep delivering small features each month.
What you get
Predictable monthly cost
A subscription plan with defined scope and hours replaces unpredictable emergency invoices, and unused capacity each month can go toward planned improvements instead of only reactive fixes.
Fewer emergencies
Proactive updates, monitoring and capacity planning catch problems early, so your team spends less time firefighting and more time on the product roadmap and customers.
Clear response times
Your software support SLA defines severity levels and response times in writing, with a single point of contact and a monthly report covering work done, issues found and recommendations.
Knowledge that stays with you
Every fix and change is documented in your repositories and runbooks, reducing dependence on any individual and keeping the system ready for whoever works on it next.

Application Maintenance & Support: FAQ
How much do application maintenance and support services cost?
Plans are typically priced as a monthly subscription based on the size and complexity of your application, the number of environments, the response times you need and the hours of enhancements you want each month. Older or poorly documented systems need more effort at first. After a free consultation and a short review of your system, we propose a plan with a fixed monthly fee.
Can you support software that another company built?
Yes. We start with a handover audit of the code, infrastructure and documentation, set up access to repositories, hosting and third-party services, and write down how the system works. In the first weeks we address the highest risks, such as missing backups or outdated dependencies, then move into regular maintenance.
What response times do you offer?
Response times for our application support services are agreed per plan and defined by severity: issues that stop your business get the fastest response, while minor bugs and small changes are scheduled into regular cycles. The SLA, contact channels and escalation path are written into the agreement, and monthly reports show how each issue was handled.
What is included in software maintenance?
Software maintenance covers four kinds of work: corrective (fixing bugs), adaptive (keeping up with new operating systems, browsers, APIs and regulations), preventive (updates, refactoring and monitoring that avoid future problems) and perfective (small improvements and features). A good plan balances all four rather than only reacting to bugs.
Why does an app need maintenance if it works today?
Because its environment keeps changing. New iOS and Android versions, browser updates, expiring certificates, deprecated APIs and newly discovered vulnerabilities can break or expose software that has not changed at all. Regular maintenance keeps those changes small and planned; skipping it tends to create a large, urgent and expensive catch-up project later.
