Where ideas ignite and code comes alive.

Developer tools, frameworks, and creative infrastructure — built with care, designed to illuminate the moment a new idea clicks into place.

A bento of developer tools.

Each compartment is a small, finished thing. Pick one, ship one, return for the next.

primary

chloengine

A render engine for documents that think — composes typography, geometry, and motion into a single layout pipeline.

v2.4 · stablemit · 2026
framework

graphers

A data graph editor with bezier joints — connect any source to any sink and watch the geometry settle.

v1.0
cli
$ desca ▌ ready

desca

A description-first scaffolding CLI. Write the project as a sentence; desca answers in directories.

v0.9 · beta
library

holos

Whole-program inference for typed configs — see your stack as one shape, not a thousand files.

v3.1
studio

chrono

Timeline scrubbing for code review — replay every change as if you were over the author's shoulder.

v1.6
extension

lossless

Round-trip transforms for binary formats — every byte you read can be written back, exactly.

tray · 03

Frameworks, paired and plated.

Two complementary surfaces. Pick the side that matches your appetite.

framework · a

completengine

A type-aware completion runtime. Suggestions arrive when you have already half-typed the future.

  • incremental parser, never re-tokenizes
  • tree-aware ranking with O(log n) cache
  • plugin surface in 14 lines of code
$ npm i @luminant/complete
framework · b

concurrengine

A scheduler for everything that wants to happen at once. Stays out of the way until it has to.

  • structured concurrency primitives
  • cancellation as a first-class signal
  • backpressure that feels mechanical
$ cargo add concurrengine
pairing

Use them together. completengine writes the next move; concurrengine runs all the next moves at once. Both share a common protocol and never block the editor thread.

tray · 04

A small studio in Tokyo.

Working hours: when the espresso is hot and the keys are clicking.

about

luminant.dev is a two-person developer studio that ships small, finished tools. We believe the warmth of a finished thing — typewritten, tested, sleeved in a paper sleeve — is worth more than ten unfinished ones.

Each release lands as a single bento tray: a clear name, a clear shape, a clear price. No subscription tiers, no enterprise upsell.
