Alternatives to JNEXT

{"intro": "JNEXT gives developers a free, GPLv3 ZX Spectrum emulator for Linux, macOS, and Windows. It covers 48K, 128K, +2A/+3, and Next Issue 2 machines, with hardware views, registers, breakpoints, and backward execution in its debugger. Headless mode and deterministic screenshots support CI testing, while its media and peripheral support includes tape and snapshot formats, DivMMC, DMA, USB gamepads, and ESP-01 networking. It can also record WAV audio or MP4 video when ffmpeg is installed.\n\nAn alternative may fit better if you need Android or iOS, broader machine coverage, an integrated editor and assembler, or a different debugging workflow. JNEXT remains under development and does not target extreme cycle-exactness. Windows may show a SmartScreen warning because its executable is unsigned, and macOS blocks the first launch until Gatekeeper approval. Compare each option’s supported machines, Next compatibility, debugger or coding tools, file formats, peripherals, and platform range. Also weigh whether a paid product, classic-machine focus, or wider emulator scope matters more than JNEXT’s developer-oriented Next support.", "rows": [{"ref": "sw:unreal-speccy-portable", "name": "Unreal Speccy Portable", "best_for": "Android users and classic Spectrum emulation", "pricing": "Free plan", "key_difference": "Unreal Speccy Portable adds Android support and focuses on Z80 and 128K systems rather than JNEXT’s Next developer tooling.", "choose_when": "Choose it when Android access, snapshots, replays, or classic tape and disk formats matter more than Next development."}, {"ref": "sw:klive-ide", "name": "Klive IDE", "best_for": "Integrated Spectrum coding and debugging", "pricing": "Free, open source", "key_difference": "Klive IDE combines emulation with an editor, assemblers, one-click builds, and debugging, while JNEXT centers on emulation and machine inspection.", "choose_when": "Choose it when you want to write, compile, inject, and debug Z80 code in one environment."}, {"ref": "sw:zx-go", "name": "zx_go", "best_for": "Broad machines and scriptable debugging", "pricing": "Free, open source", "key_difference": "zx_go emulates ZX80, ZX81, Pentagon, SAM Coupé, and Spectrum Next, with visual, telnet, and headless debugging beyond JNEXT’s machine range.", "choose_when": "Choose it when broader Sinclair coverage, cycle-accurate classic emulation, or ARM64 binaries outweigh incomplete Next game compatibility."}, {"ref": "sw:cspect", "name": "CSpect", "best_for": "ZX Spectrum Next development with plugins", "pricing": "Free plan", "key_difference": "CSpect adds an assembler, plugin system, ULA overlays, and z88dk map-file support, while JNEXT offers broader peripherals and CI automation.", "choose_when": "Choose it when assembler workflows, symbol plugins, or direct z88dk map integration are central to your Next projects."}, {"ref": "sw:gzx", "name": "GZX", "best_for": "Simple classic Spectrum emulation", "pricing": "Free plan", "key_difference": "GZX targets 48K, 128K, +2, and +2A systems with tape conversion, ULAplus, Spec256, and MIDI, but no Next emulation.", "choose_when": "Choose it when classic models, tape-format conversion, or MIDI matter and you do not need JNEXT’s Next hardware."}, {"ref": "sw:spectaculator", "name": "Spectaculator", "best_for": "Paid multi-platform emulator with Windows tools", "pricing": "From $2.99 · 30-day trial", "key_difference": "Spectaculator supports Android, iOS, and Windows and offers a paid Windows debugger, whereas JNEXT is free and Next-focused.", "choose_when": "Choose it when iOS or Android access, configurable game controls, or Spectaculator’s Windows inspection tools justify paying."}, {"ref": "sw:zesarux", "name": "ZEsarUX", "best_for": "Multi-system emulation and accessibility", "pricing": "Free plan", "key_difference": "ZEsarUX covers many Sinclair and other systems, adds reverse debugging, multiplayer, capture, and text-to-speech support beyond JNEXT’s scope.", "choose_when": "Choose it when wider machine coverage, multiplayer, accessibility features, or Visual Studio Code debugging integration are priorities."}]}
