WinDev Migration:
the free way, from the Tauri
free to sovereign SaaS.
Migrate your WinDev, WebDev and WinDev Mobile applications to open technologies: free Tauri executable (Windows, macOS, Linux), ISO 27001 certified sovereign SaaS, iOS and Android applications. Your code, your data, your independence — zero PC SOFT royalties.

PC SOFT acquired by Volaris — session billing is in place
PC SOFT was acquired by Volaris Group, specialist in the acquisition of business software at the end of the cycle. The perpetual license is gone. Billing changes per session — approximately €290 excl. tax/session/year. For a company with several dozen positions and a few developers, the invoice can be multiplied by 20 in one year, as happened to the Vinci Group.
Sources: Next.ink, Programz!, written question to the National Assembly, Wx Alliance collective — numbers sourced and dated. The multiplier ×20 is the actual figure observed at the Vinci Constructions Group (authorised communication).
It's not a trend — it's a fact. And contrary to what you might think, migration does not take 18 months. It takes 2 weeks of generation + 1 week of controls, if you use the right forge.
The double Vinci ERP generated
in 2 weeks
Vinci Constructions Group
Authorized communication · 2 ERP international deployment annexes
Two full international site ERPs — approximately 300 screens and 200 states each, 1000 total users worldwide. WinDev/PC Soft pricing had been multiplied by 20 in one year for these 1000 users — several hundred thousand euros per year if the group stayed on this billing.
This project served as the basis for building the WinDev WakaStart SaaS → B2B automated forge. More than a month to adapt WakaNalytics and the forge to the WinDev context — especially for the engine able to take over the 40,000 pages of documentation of this big ERP. Then: reverse engineering + mock-ups + generation of B2B SaaS code in 2 weeks, + 1 week of final checks before going live. WakaStellar committed to a result before the end of the year.

There are three approaches to getting out of WinDev. Here's what they say about the criteria that really matter.
| Criteria | ESN / agency rewrite | No-code platform | ✦ WakaStart Forge |
|---|---|---|---|
| Cost | €50k€→3M + | Membership with Subscription | €0 (Tauri) /€15-60k (SaaS) |
| Deadline | 3 to 18 months | Variable | 2 weeks + 1 week controls |
| Code Ownership | Variable according to contract | Platform Enclosure | 100% — your Git deposit |
| Post-delivery dependency | Third party maintenance | Subscription required | Open Stack, Standard TypeScript |
| Compliance with ISO 27001 / NIS2 | Non-native — separate project | Rarely included | Native on delivery (WSIS WakaStart) |
| Sovereign Hosting France | According to provider | Often US (AWS, GCP) | OVH France — Cloud Act waterproof |
| No dev skills required | No | Partial | Yes — project management is enough |
| Guaranteed HFSQL recovery | According to team | Rarely included | Included, Compliance Report |
How much does it cost you
staying?
With ~ €290 excl. tax/session/year, the cost explodes with the number of users. Our calculator gives you in 2 minutes: what PC SOFT is costing you today, what your migration would cost, and the number of months before return on investment.
Three exit routes,
a single software forge.
Choose the path that suits your situation. The same WakaStart forge generates all three — only the output stack and the level of accompaniment change.

An agentic forge,
not a quick one.
No AI converts a WinDev app “with a click” — and those who promise to do so are lying to you. WakaStart industrializes what is automatable and keeps a human on each validation.
The business logic of your application is captured then regenerated by the WakaStart forge : code aligned with our reference stack, declarative architecture imported in JSON, containerized services deployed on our Kubernetes farm, Keycloak identities and SSOs, interface modernized by WakaUI.
The safeguards are non-negotiable: human review of the generated code, screen-by-screen equivalence tests, blank data replays, table-by-table compliance report.
Key Differentiating Argument
Only the project management and business understanding — in no way a language. Neither TypeScript nor Rust to know. The Waka skills and the specialized agents of the forge design the models, deploy and correct the bugs reported in the test.
Why it's different
Without safeguards, a general-purpose AI codes freely and deviates. At WakaStart, the list of authorized components is closed and controlled, and the alignment between the generated code and the deployment infrastructure makes deviation impossible.
