# CodeShift AI > CodeShift AI is a software service for small and medium businesses. We modernize legacy applications, build custom replacements for overpriced SaaS tools, and deploy AI-built prototypes to production. The work is done by supervised AI agents, personally overseen by an experienced principal engineer, delivering production-quality software in a fraction of the time and cost of traditional consulting. Website: https://codeshiftai.com Contact: info@codeshiftai.com Audience: Small and medium businesses (not enterprise) Service area: Worldwide / remote ## Services - [Legacy Code Modernization](https://codeshiftai.com/legacy-modernization): Transform outdated desktop applications — WinForms, Visual Basic, legacy Java, Classic ASP, PowerBuilder, Delphi, FoxPro, Microsoft Access — into modern, secure, cross-platform web and mobile software (React, React Native, TypeScript, Progressive Web Apps). Delivered in a fraction of the time and cost of a traditional 12–18 month rewrite; projects typically quote between $15,000 and $60,000 as a fixed price (traditional consultancies quote $100,000+). Full guide: https://codeshiftai.com/legacy-modernization - [SaaS Replacement](https://codeshiftai.com/saas-replacement): Build lean, custom alternatives to overpriced SaaS subscriptions — mailing lists/listservs, CRMs, scheduling and booking tools, reporting dashboards, project/task trackers, inventory/order tracking. Hosting often costs under $20/month, and the client owns the code and data outright with no vendor lock-in. Replacements can be delivered as web apps or as installable desktop apps (Electron) with data stored locally. Replacements typically quote between $5,000 and $20,000 fixed—roughly one to two years of the subscriptions they replace. Full guide: https://codeshiftai.com/saas-replacement - [Launch Assist](https://codeshiftai.com/launch-assist): Take a prototype built with AI tools (Claude, Cursor, v0, Lovable, Replit, Bolt) or a GitHub repo and ship it to production. Includes code review and security hardening, infrastructure set up under the client's own accounts (Vercel, AWS, Cloudflare), and a plain-English handoff. Fixed scope, designed to finish in days, not weeks; engagements typically quote between $2,500 and $7,500, with a straightforward review-and-launch starting at $2,500. Full guide: https://codeshiftai.com/launch-assist ## How it works Full engagement walkthrough: https://codeshiftai.com/how-it-works 1. Reach Out — A plain-words message that goes straight to the founder; reply within 1–2 business days. No code or documentation required up front. 2. Free, Honest Assessment — Share code, the current tool, or a prototype when comfortable (or via a call/screen share); the client gets scope, timeline, cost, and an honest fit-check — including "not worth building" when true. 3. Scope & Price Up Front — Clear scope, timeline, and cost agreed before any commitment; every project is a fixed quote, and typical price ranges are published on each service page. 4. Supervised Build — AI agents do the heavy lifting; an experienced engineer reviews every step for security, quality, and maintainability (not unreviewed AI output). The client's current app or tool keeps running throughout. 5. Delivery & Handoff — Fully functional, tested, documented code with hosting accounts and data in the client's name, plus a plain-English owner's manual. 6. After Launch — The client can run it themselves (hosting usually under $20/month) or choose an optional care plan: Hosting & Care at $99/month (hosting, monitoring, backups, updates, small fixes) or Hosting & Support at $299/month (adds monthly change hours and priority response). No lock-in—the client can take everything over at any time. ## Key facts - Powered by supervised AI agents with human engineering oversight — production-quality code, not "AI slop." - Clients keep full ownership of code, data, and infrastructure; no vendor lock-in to CodeShift AI. - A free initial code analysis and estimate is provided before any commitment. - Pricing is published and fixed-quote: Launch Assist typically $2,500–$7,500; SaaS Replacement $5,000–$20,000; Legacy Modernization $15,000–$60,000.
