Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. The goal of Virtual T is to provide 100% hardware emulation so any existing programs will run. It also adds powerful development and debugging tools.
GXemul is a full-system computer emulator, emulating processors (ARM, MIPS, M88K, PowerPC, and SuperH) and surrounding peripherals, in some cases well enough to let unmodified guest operating systems run as if they were running on real hardware.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
ClassGhost is a small utility that can redefine class files within a running JVM. ClassGhost allows you to directly inject the newly compiled class files in to the VM without interrupting the running application. Works with multiple as well as remote VMs
Dinaao Is Not An Apple One Emulator.
It does however already run most apple1 software. It runs on the command line so cut and paste works perfectly. A great 65C02/Basic learning/development environment.
A multi-ISA "assembly debugger" with graphical and terminal frontends. Currently sporting LC-3, Georgia Tech's LC-2200, and brain*. MIPS support is in the making, to compete with SPIM. (Windows, Linux, MacOSX; LC-3 simulator and LC-2200 simulator)
JDLabAgent is a dynamic link library which is loaded into the Java Virtual Machine via Java Virtual Machine Debug Interface (JVMDI). The JDLabAgent can be parameterized via config files and logs JVM events (e.g. breakpoints, exceptions).

NEmu is an emulator/simulator for exploring computer architecture. It
provides a virtual machine, a debugger, and simulations of various cpus
and hardware. NEmu is built on top of ALib, my own application framework.
The XPS is a scalable platform for meta-programming and domain engineering. It provides a virtual machine, compiler, and runtime library that make it possible to efficiently develop, debug, and run programs based on XPL (eXtensible Programming Language)
jDiSeq is a recording facility for call sequences within any Java Virtual Machine. Typical usage is to generate UML (Unified Modeling Language) sequence diagrams of a running system - client or serverside.
zdb is an effort to create a source level debugger for Inform, the modern programming language of the Z-machine. The Z-machine is the virtual machine created by Infocom for distributing text adventures.
LLVM is a unique compiler infrastructure designed for the optimization of programs from arbitrary programming languages. Compilation in C and C++ programs is supported using a parser based on GCC 3.4. Backends exist for X86, Sparc, PowerPC and "C".
A FrameWork to develop Pascal Applications. This includes Integrated Development Environment (Rapid Application Development -RAD-), Virtual Machine, Web Services (Pascal Server Pages -PSP-) and too many tools
xdProf is a tool that captures and analyzes stack traces sent at a fixed interval from Java Virtual Machines in a distributed system. The xdProf client uses a C/C++ Java Virtual Machine Profiling Interface (JVMPI) library and works on many platforms.
This provides an interactive, programmer-friendly interface to VMware's VProbes facility. VProbes is a safe, dynamic technology for instrumenting software running in virtual machines, and the software stack itself.
