D10Labo is a Japanese audio software developer founded by Masaru Saito, a programmer and dub techno musician who also runs the Different10 techno label. The brand specializes in VST/AU plugins for macOS and Windows, distributing both free and paid instruments and effects through its own storefront and outlets like Plugin Boutique.

The company's catalog centers on synthesizers and rhythmic effects. Synth offerings include ModSynth and its monophonic counterpart ModSynthMono — instruments inspired by classic hardware such as the EMS Synthi A, Sequential Circuits Prophet-5, and Oberheim Xpander, with matrix-style modulation routing — alongside other designs like the LowBitSyn, MSyn, and TBSyn families. On the effects side, the multi-tap RhythmDelay and its free version RhythmDelayFree are designed for building musical rhythmic patterns rather than conventional echo, with eight independently controllable taps, tempo sync, and an analog-style fixed low-pass filter on the feedback path.

D10Labo's plugins lean toward minimal and techno production workflows, reflecting the label's roots, and the developer emphasizes intuitive, focused interfaces over deep menu-diving. Free versions of several instruments and effects are made available alongside the paid lineup, which has helped the brand build a presence on plugin archives and demo channels among bedroom producers and techno musicians.

D10Labo has 4 products cataloged on Equipboard, including Synth Plugins and Delay Plugins.
