Port Desk: VB6 and Access ports for small businesses, now that OpenAI claims a legacy-language leap
Agent-assisted rewrites of a small firm's VB6 or Access app as a web app. Owners pay a fixed price per port.
Competitive · OpenAI's legacy-language model gains
Written for: Solo builder
Next step
Write the VB6 Inventory CLI this week and test it on three open-source VB6 projects from GitHub. Then offer five free port estimates on r/visualbasic and r/MSAccess.
Why now
The earlier Port Desk card relied on general coding-agent skill. Now a frontier lab is targeting Visual Basic migration by name, which should improve how well models read VB6 forms and Access queries. The bank and government COBOL work is enterprise procurement, so stay out of it. The solo-sized end is the dental office, distributor or accountant still running a 2004 VB6 app. MiniMax M3.1 Flash, at under $0.30 per coding task on DeepSWE, also makes bulk translation passes cheap.
What became possible
OpenAI says its latest models show major performance leaps in low-resource languages such as COBOL, Fortran and Visual Basic, specifically for building and migrating software.
Two ways in
- VB6 Inventory
A free CLI that scans a VB6 project or an .mdb/.accdb file. It reports form count, database calls, COM/OCX dependencies and reports, and gives an estimated port price.
- Customer
- Small-business owners and their part-time IT contractors
- Model
- A free lead magnet that feeds the paid port
- Port Desk fixed-price port
Converts the app to a hosted web app with data migration and side-by-side screenshots for acceptance. It is priced per form and report.
- Customer
- 5 to 50 person firms running a single line-of-business VB6 or Access app
- Model
- $3k to $15k per port plus $99 per month hosting and support
Competition
The core technology is already taken. GAPVelocity converts both Access and VB6, forms and logic included, with agentic AI.
Full competition notes (9 competitors)
The core technology is already taken. GAPVelocity converts both Access and VB6, forms and logic included, with agentic AI. Legacyleap and similar shops handle VB6 and Delphi to React. Microsoft gives away a free path from Access data to Dataverse. General coding agents with open-source Access export skills let any consultant attempt the port by hand. What I did not find is a product built for the bottom of the market. Nobody offers a self-serve, fixed-price service where a 5 to 50 person firm uploads one .accdb or VB6 project and gets back a working hosted web app with its data migrated. Nobody runs it as a managed service on non-Microsoft hosting. And no current vendor offers a white-label kit for small MSPs, which today either resell Power Apps rebuilds or quote custom work. The incumbents sell developer-tool licenses or enterprise engagements built on .NET, Blazor or Angular, so they are not set up for many small, cheap jobs. A new entrant could win on three things. The first is fixed pricing per app. The second is hosting and ongoing upkeep as recurring revenue. The third is MSP distribution, ideally with checks that the migrated app still behaves the same. The risks are real. Every small app comes with its own one-off VBA, reports and Excel or Outlook automation, which makes high automation rates hard to reach. Small firms will pay little. And the work could slip into low-margin services unless the agent really handles the long tail of edge cases.
- GAPVelocity AI (formerly Mobilize.Net) VELO / WebMAP for Access
The closest direct competitor. It uses agentic AI to convert .mdb and .accdb apps, including forms and VBA, into C# and Blazor, or Angular through WebMAP, with the data moved to SQL Server. It also has an AI VBA extractor for assessment. It is aimed at enterprise and mid-market buyers, it does not host the result for you, and it targets the Microsoft stack.
- GAPVelocity VB6 AI Migrator (VBUC)
The established VB6 converter. It outputs C#, VB.NET or Blazor, and an Angular AI Migrator handles web output. The free trial covers 10k lines. It is licensed as a tool for developers, not as an upload-and-host service for small firms.
- Legacyleap
A GenAI modernization platform for VB6, Delphi and Classic ASP that targets React plus .NET. Its vendor case study reports 60 to 65 percent automation. It is enterprise and services-led, and Access is not listed as a supported source.
- Legacy Zero (MetaDesign Solutions)
An agentic AI modernization service covering VB6, Delphi and COBOL, with React and Next.js among its targets. It is a consultancy offer, not a self-serve product.
- Microsoft Access migration to Power Apps and Dataverse
Microsoft's free, generally available tool. It moves tables, relationships and data to Dataverse, and you then rebuild the front end in Power Apps. It does not convert forms or VBA, but it is the default path many MSPs already sell.
- m-Power (mrc) Access to Web
Moves Access tables into a relational database and generates web and mobile apps on top of them. It is a low-code platform, not a faithful port of the original forms.
- Thinfinity VirtualUI
Runs the existing Access app in a browser through remote display rather than rebuilding it. It is a cheap stopgap that competes for the same small-business customer who just wants to reach the app from the web.
- DaDaBIK and Jampy
Self-hosted web database builders that import the Access data but leave you to recreate the forms and logic by hand.
- ms-access-ai-skill (open source)
A Claude Code and OpenCode skill that exports .accdb forms, modules and queries to text. It shows that consultants can already point general coding agents at Access apps themselves, which is a do-it-yourself substitute.

Risks
- OpenAI's gains are self-reported, with no independent benchmark yet
- This is service revenue that doesn't scale, and clients expect support forever
- Third-party OCX controls and Crystal Reports are where ports stall
