Application Maintenance & Support
Ongoing technical ownership of the web application your business depends on.
Someone has to own it. That is what we do.
A live web application is never "done". PHP versions reach end of life, dependencies need security patches, cron jobs silently fail, queues back up, integrations change their APIs, and the database grows until yesterday's fast page is today's timeout. Application maintenance is the discipline of catching these things before your customers do.
Synapse Code provides long-term maintenance and support for existing PHP, Laravel and Symfony applications — SaaS products, booking and travel platforms, e-commerce backends, B2B portals and internal business systems. We work as your standing technical partner: same people, accumulated knowledge of your system, no re-onboarding every time something breaks.
Incidents jump the queue
Stability and incident response take priority over everything else.
We stay for years, not tickets
We take ownership for years, not tickets — our founder's longest client relationship ran for five years.
You see what was done, and why
Clear reporting on what was done, why, and what we recommend next.
what maintenance covers
Incident resolution, monitoring, log analysis, and fixing the recurring failures behind them — including cron jobs and queue workers. We once stabilised production cron jobs that were accumulating and exhausting server memory.
A steady stream of fixes and quality-of-life improvements, so the application keeps getting better instead of slowly rotting.
Dependency updates, security patches, PHP and framework version currency — handled routinely, not in a panic after an advisory.
MySQL/PostgreSQL care, slow-query work and caching with Redis. We took one client's Laravel search page from ~17 seconds to ~1 second.
Keeping third-party integrations alive as external APIs evolve — payments, availability, pricing, e-commerce and operational systems.
AWS, Docker, deployment pipelines and backups — reviewed, documented and kept healthy as part of the retainer.
what a month looks like
Patched on a schedule, not after an advisory
Updates, security patches and fixes applied on a schedule — not in a panic after an advisory.
Incidents first
When production breaks, it jumps the queue — ahead of every piece of planned work.
Plain language, not ticket jargon

framework-specific maintenance
The day-to-day of maintenance differs by stack. See the dedicated pages for your framework:
Queues, Horizon, scheduler, Eloquent performance, version upgrades.

Yes — it is one of our core services, and the previous developer does not need to be available. We audit access and code, stabilise anything urgent, then move to ongoing maintenance. See application takeover.
Production incidents are prioritised ahead of all planned work, and we reply within one business day. Specific response commitments are agreed in your maintenance arrangement — see How We Work.
A monthly retainer sized to your system and how fast it changes, agreed after the System Risk Check — so the number is based on evidence, not guesses. Bigger features run as time-and-materials projects alongside the retainer. Details on the pricing page.
Yes. AWS and other hosting, Docker, deployment pipelines, backups, and MySQL/PostgreSQL care are part of the maintenance scope — one accountable partner for code, database and infrastructure.

Start with a System Risk Check
Before any retainer, we review your application and send you a written report: current risks, quick wins, and what ongoing maintenance should cover. No obligation to continue.
