What published AngularJS migration prices look like
| Application | Usual approach | Timeline | Published budget |
|---|---|---|---|
| Small SaaS tool | Hybrid — old and new side by side | 1–4 months | $10,000–$40,000 |
| Mid-size product | Hybrid or rewrite | 4–9 months | $40,000–$150,000 |
| Large enterprise system | Mostly rewrite | 9–12+ months | $150,000–$300,000+ |

The deadline has already passed
AngularJS’s own documentation states that “AngularJS support has officially ended as of January 2022” (AngularJS, version support status). An application still running on it is not about to become unsupported; it has been unsupported for years. The risk grows quietly — with every browser change, every dependency that moves on, and every developer who leaves.
What moves the number
| What the application has | Why it matters |
|---|---|
| Many components and screens | Size is still the first driver — 20 components and 200 are different projects |
| Unused screens and features | Everything retired is something not rebuilt |
| Tangled or untested code | Behaviour has to be understood before it can be moved |
| Third-party plugins and UI kits | Each needs a modern replacement, or a rewrite |
| No documentation, original developers gone | Comprehension becomes part of the work |
| Integrations and sign-in | The parts users notice first if anything changes |
Retire before you migrate
The cheapest line in any migration is the one you delete. One firm puts it plainly: “Most aging AngularJS apps carry screens and features nobody uses. The cheapest migration is the one where you retire that code instead of rebuilding it” (Full Scale, 30 August 2026). Find out what is actually used before anyone prices moving it.
Module by module, not big bang
For anything beyond a small tool, move one part at a time while the old application keeps running the rest, and prove each part matches before it switches over. Nothing goes dark on a cut-over day, and a traceability matrix answers the real fear — that something nobody remembered quietly disappears.
What to have ready before you ask for a quote
- Roughly how many screens the application has, and which are actually used
- Which plugins and UI libraries it depends on
- What it talks to — APIs, sign-in, other systems
- Who uses it, and which parts can never go down
How Pricient quotes a modernization
Modernization starts with a Legacy System Specification Assessment. It produces a written specification, a risk register, a keep-vs-replace cost comparison and a staged replacement plan, and its fee is credited in full against the first build stage if it starts within 90 days of the report. You can start with a conversation about the system; we ask for read-only code access only when the assessment begins. Tell us what you are running and you get a fixed quote for the assessment.
