KeelenAnswer — after launch
How do I maintain my app after launch?
Updated 20 August 2026
Post-launch maintenance is five recurring jobs: keep dependencies patched, fix the errors real users hit, keep the tests and CI green, make small improvements users ask for, and watch security. You can buy that as an agency retainer, hire a part-time developer, do it yourself on a schedule, or run an autonomous dev loop against the repository. The mistake is assuming maintenance is optional: an unmaintained app does not stay still, it decays, because its dependencies and platforms keep moving underneath it.
Price the options against each other honestly. An agency retainer buys accountability and human judgement. A loop buys throughput on a flat monthly fee. Most small products need more throughput than judgement most weeks, and a human on the weeks that matter.
What to do, in order
Automate dependency updates
Turn on automated dependency pull requests and make sure CI runs on them. Most security exposure in a small app arrives through dependencies nobody updated, not through code anybody wrote.
Put error monitoring in front of your users
You cannot fix what you never see. An error tracker tells you which failures real users hit and how often, which is a far better backlog than guessing.
Keep the test suite and CI green
A red build that everyone ignores is the same as having no tests. Whoever maintains the app has to keep the gate meaningful, because every later safety mechanism depends on it.
Ship small improvements on a rhythm
Maintenance that only ever fixes things feels like decline. A small visible improvement each week is what keeps users and the people paying for the work engaged.
Review security on a cadence, not after an incident
Schedule a repository-wide review: code, secrets in history, dependencies, and infrastructure config. Monthly is enough for most small products.
What maintenance actually costs
Agency retainers are priced for a team and accountability, and they are the right answer when you need someone to own outcomes. A part-time freelancer is cheaper and depends on one person's availability. Keelen is a flat monthly tier ($29 for Indie, $79 for Operator) plus your own model subscription at cost, and it supplies throughput rather than accountability. Pick by which of those two you are actually short of.
How a loop covers the recurring jobs
Requests become roadmap items and tasks; the loop implements them, proves the new tests fail before the fix, has an independent reviewer read the diff, runs your suite on a clean checkout, and waits for CI. Scheduled scans cover the security half. Failed runs are classified into 30 kinds. Infrastructure blips and provider limits retry on a budget and never count against your work. A real dead end becomes one plain-English card in your Needs-you queue with a recommended action, and the project pauses rather than burning quota.
Keeping a human in the decisions that need one
Autonomy is a per-project setting, not a personality. Plan review makes a human approve the plan before any code is written. Manual merge means Keelen opens the pull request and you click merge. Branch-only means it pushes a branch and never opens a pull request at all. Pause one project or the whole fleet whenever you want the keyboard back.
What runs where, and what it can touch
Every iteration runs in its own single-use, non-root VM that is destroyed when the run ends. Network egress is deny-by-default through a proxy. The GitHub token an iteration holds is scoped to one repository for about an hour and cannot modify your CI workflows.
When Keelen is not the answer
- You need someone accountable on a phone at 3am. A loop is not an on-call engineer, and Keelen makes no uptime promise about your app.
- Your app is closed source and not in a Git repository Keelen can connect to.
- You want a single human who holds the whole product in their head. That is a hire, not a subscription.
Hand the work to a loop
Connect a repository, write what you want in plain language, and review the tested pull requests that come back.
FAQ
How much should app maintenance cost per month?
It depends on what you are buying. Agency retainers price a team and accountability. A freelancer prices hours. An autonomous loop prices throughput: Keelen is $29 to $79 a month plus your own model subscription at cost. Compare on what you are short of, not on the headline number.
Can AI handle maintenance on its own?
It can handle the recurring engineering work: dependency updates, error fixes, small improvements, test upkeep. It cannot own the consequences of a decision. Keep a human on approvals for anything irreversible, which is exactly what plan review and manual merge are for.
What happens if a change breaks production?
Nothing merges over a red required CI check, and your own suite runs on a clean checkout before that. If something still gets through, the fix is the same as with any team: revert the pull request. Every change is one reviewable, reversible pull request for exactly this reason.
Does it work on a repository someone else wrote?
Yes. That is the common case. It reads the repository, detects the stack and the test command, and works from there. On an inherited codebase, run a security scan first so you know what you have before changing it.
