Legacy Modernization

Feed it COBOL.
Get back working modern code.

Recodex is an AI agent that translates your legacy COBOL into production-ready Java, Go, or Python. Business logic preserved. Dependencies mapped. Functional equivalence verified.

Input: COBOL
IDENTIFICATION DIVISION. PROGRAM-ID. CALC-INTEREST. DATA DIVISION. WORKING-STORAGE SECTION. 01 WS-PRINCIPAL PIC 9(9)V99. 01 WS-RATE PIC 9(3)V99. 01 WS-INTEREST PIC 9(9)V99. PROCEDURE DIVISION. COMPUTE WS-INTEREST = WS-PRINCIPAL * WS-RATE / 100 STOP RUN.
Output: Go
package finance import "math/big" // CalcInterest computes simple // interest on a principal amount. func CalcInterest( principal *big.Float, rate *big.Float, ) *big.Float { hundred := big.NewFloat(100) result := new(big.Float) result.Mul(principal, rate) result.Quo(result, hundred) return result }

Business Logic First

Recodex doesn't just translate syntax. It understands decades of embedded business rules and preserves them in clean, documented modern code.

🔀

Multi-Target Output

Java, Go, or Python from the same COBOL source. Pick the language that fits your team and infrastructure. No vendor lock-in.

✅

Verified Equivalence

Every translation includes automated functional equivalence testing. The output doesn't just compile. It behaves identically to the original.

The mainframe era built the world's infrastructure. Recodex carries it forward.

Decades of business logic shouldn't die with a programming language. We make sure it doesn't.
