We keep software running — even code we didn't write
Maintenance, monitoring, security patching, and ongoing features — with SLA-backed response times. We take over codebases other teams built, and we maintain production platforms end-to-end, including NriHearts with its CI/CD and monitoring. From $1.5k/month.

Keeping software healthy, not just alive
Plain list. Every retainer covers the essentials.
Proof
We run production platforms end-to-end
Maintenance isn't a side service for us — we keep real products running.
Maintained by us
A live platform in 50+ countries with CI/CD, monitoring, and ongoing feature delivery.
We adopt others' code
Audit first, stabilize, then a roadmap — a large share of our maintenance work.
Real response times
Retainers with defined response times and on-call coverage by tier.
Know the number before you commit
Retainers start at $1.5k/month and scale with SLA tier (response times, on-call coverage) and codebase size. Every retainer includes monitoring, security patching, and a monthly health report.
How it works
Stabilize first, then improve
Whether it's our code or someone else's, we make it healthy before we build on it.
Audit the codebase
Understand what you have, including the risks nobody documented.
Stabilize
Fix what's fragile and get monitoring in place.
Maintain to SLA
Patching, fixes, and features within agreed response times.
Report monthly
A plain health report so you always know the state.

Software maintenance at Essen Software is ongoing support for your codebase—technical audit, patches, refactors, 24/7 monitoring, tiered SLAs (e.g. 1-hour P0), and FinOps to optimize cloud costs.
Yes. We specialize in takeover projects: detailed technical audit, safe transition, then planned sprint cycles (patches, refactors, deploys) with clear SLAs.
Tiered SLAs: critical P0 typically 1-hour response with 24/7 options. We also do FinOps—optimizing instance sizes and reservations to shrink your cloud bill.

Yes — takeovers are a large share of our maintenance work: audit first, stabilize, then a roadmap. We maintain production platforms end-to-end — including NriHearts.com with its CI/CD pipeline, monitoring, and ongoing feature delivery.
Why choose Essen for software maintenance
Need software kept healthy — even if you didn't build it here?
Thirty minutes. Tell us what you're running. We'll tell you honestly what maintenance it needs, what it costs, and how we'd take it over if another team built it.
