the online 8086 emulator — no account needed
online8086.com is a free online 8086 emulator: write 8086 assembly and
press Run to actually execute it, right here in the browser — no install, no login, nothing
to sign up for. Whatever's in the box saves to this browser automatically, so it's still here
next time you visit — but it never leaves your device. Pick an example below to start from,
upload a .asm file of your own, or clear it and write from scratch.
Supports: MOV / LEA / ADD / SUB / INC / DEC / MUL / DIV / CMP / JMP / JE / JNE / JG / JL / JGE / JLE / LOOP / CALL / RET / PUSH / POP / INT 21h / REPE CMPSB, plus .MODEL/.STACK/.DATA/.CODE/PROC/ENDP/DB/DW/EQU/DUP/OFFSET/END.
