The verdict in three sentences
When the freelancer who built your application disappears, the top priority is to recover access (hosting, domain name, Git repository, database) before touching any code. A code and infrastructure audit then costs 2,000 to 5,000 EUR (about 2,200 to 5,500 USD) in 2026 and takes 5 to 10 business days. Remediation ranges from 5,000 to 25,000 EUR, and in 40% of cases a partial rewrite costs less than fixing the code module by module.
Step 1: recover access before it is too late
An orphaned application often depends on accounts held by the freelancer: a personal card on the hosting provider, a domain registered in their name, a private GitHub repository. If the card expires or the domain is not renewed, the service stops overnight. List every asset, its owner and its renewal date.
| Asset | Risk if not recovered | How to recover it | Typical delay | 2026 indicative cost |
|---|---|---|---|---|
| Domain name | Site down at expiry | Registrar procedure with company registration and proof of payment | 5 to 15 days | 0 to 300 EUR |
| Hosting (AWS, OVH, DigitalOcean) | Shutdown if card expires | Change of account owner or migration | 2 to 10 days | 500 to 2,000 EUR migration |
| Git repository | No reliable version of the code | Formal request, otherwise extraction from the server | 1 to 20 days | 300 to 1,500 EUR |
| Database | Loss of business history | Dump from the production server | 1 day | 200 to 600 EUR |
| Third-party accounts (email, SMS, APIs) | Notifications and payments cut off | Recreate keys under your name | 1 to 3 days | 300 to 900 EUR |
| Documentation | Slow, expensive takeover | Reverse documentation during the audit | Included in audit | 0 EUR extra |
Send the freelancer a polite formal notice by registered mail referring to the IP assignment clause in your contract. If there is no contract, a lawyer typically charges 800 to 1,500 EUR to secure ownership of the code.
Step 2: the audit and what it must deliver
A serious audit is more than a general opinion. It must produce a quantified assessment: framework version and update backlog, test coverage, known vulnerabilities in dependencies, database quality, hosting cost and a reasoned recommendation between fixing, partial rewrite and full rewrite.
| Audit format | Price 2026 | Duration | Deliverables | Suited to |
|---|---|---|---|---|
| Flash | 1,200 to 2,000 EUR | 2 to 3 days | Inventory, critical vulnerabilities, immediate risks | App under 20 screens |
| Standard | 2,000 to 3,500 EUR | 5 to 7 days | Flash + code quality, costed technical debt, takeover plan | Most common case |
| In-depth | 3,500 to 5,000 EUR | 8 to 10 days | Standard + load tests, GDPR review, costed scenarios | Critical app or 50+ users |
| Remediation | 5,000 to 25,000 EUR | 3 to 10 weeks | Updates, fixes, tests, automated deployment | Salvageable code |
| Partial rewrite | 10,000 to 30,000 EUR | 6 to 12 weeks | Critical modules rebuilt, data kept | Fragile code on 40% of scope |
Fix or rewrite: the decision rule
A partial rewrite wins when three signals add up: a framework out of support for more than 2 years, no automated tests at all and business logic duplicated across several files. In that case each fix breaks something else and maintenance cost climbs 30 to 50% a year. Conversely, well-structured code on a recent Laravel, Symfony or Next.js version can be brought back into shape in a few weeks.
A useful benchmark: if remediation exceeds 60% of the cost of rewriting the same scope, rewrite the affected modules while keeping the database.
Mini case study
Thomas, managing director of a 60-employee industrial cleaning company in Bristol, has heard nothing for 4 months from the freelancer who built his team scheduling app. He recovers the domain and hosting in 10 days for 900 EUR, then orders a Standard audit for 2,800 EUR.

The audit reveals a framework unsupported since 2023 and an untested scheduling module that accounts for 70% of bugs. Fixing everything would cost 19,000 EUR. Rewriting only the scheduling module and updating the rest costs 14,500 EUR. Thomas chooses the partial rewrite. Total cost: 900 + 2,800 + 14,500 = 18,200 EUR. His team leads were losing 5 hours a week on manual corrections, about 9,000 EUR a year of staff time: the project pays back in just over 2 years, not counting the avoided risk of a shutdown.
FAQ
How much does an application audit cost in 2026?
Expect 2,000 to 5,000 EUR depending on the size of the application, for 5 to 10 days of work. A flash audit on a small app starts around 1,200 EUR.
Do I own the code if the freelancer has left?
Only if your contract includes a written assignment of intellectual property rights. Without it, the freelancer keeps the copyright and you need to regularise, usually through a signed amendment.
What if I have no access to the Git repository?
The code deployed on the production server can be extracted, provided you have hosting access. Allow 300 to 1,500 EUR to rebuild a clean repository.
Should a legacy application always be rewritten?
No. In about 60% of cases, remediation between 5,000 and 15,000 EUR is enough. A partial rewrite is justified when fixing exceeds 60% of the cost of a rewrite.
How long does a takeover take?
Access secured in 1 to 3 weeks, audit in 1 to 2 weeks, then 3 to 12 weeks of work. A full takeover therefore takes 2 to 4 months.
