Offline-first engineering workspace

Build reusable calculators and local mini tools with MicroCAS

MicroCAS is built for people who want more than a fixed calculator app. Create your own calculators from formulas, build local mini tools with HTML, CSS, JavaScript, and Python, and keep technical references, saved results, and reusable workflows together on your device.

Why MicroCAS

Freedom beyond a fixed calculator app

Instead of spreading formulas, utilities, references, and saved calculations across disconnected browser tools, notes, and spreadsheets, MicroCAS keeps them together in one local-first workspace. The result is a more durable technical setup that stays useful in the office, on site, in transit, in secure environments, or anywhere internet access is limited.

Calculator freedom

Unlimited

Create as many custom calculators as your workflows need instead of waiting for built-in tools to match your use case.

Local-first usage

Offline

Core workflows stay available without depending on cloud services, accounts, or a live internet connection.

Portable work

Transferable

Save, migrate, import, export, and share calculators or mini tool workspaces whenever you choose.

Builder starters

Template-ready

Start from web, Python, or FastAPI plus frontend templates and continue development later on another device.

Built for real workflows

Reusable calculators and a programmable Mini Tool Studio

MicroCAS combines built-in technical tools with user-created calculators and local mini apps, so recurring calculations and small workflow helpers become reusable assets instead of disposable scratchpad work.

Reusable formulas

Units and labels

Graphing ready

Custom calculators

Create simple helpers or more advanced multi-variable calculators for recurring engineering work. Add names, descriptions, labels, units, preview images, and richer options such as graphing or numerical calculus support.

Create unlimited calculators from your own formulas.
Save, reuse, favorite, import, export, migrate, and share them when needed.
Use one smart input for formulas, equations, conversions, and technical queries.

Mini Tool Studio

Build small local tools around your own workflow, whether that means a technical micro-app, a quick prototype, or an internal helper. You control the code, keep the workspace local, and continue later without being tied to a cloud editor.

Core capabilities

A local workspace shaped around technical work

Everyday speed

Smart technical input

Use one input flow for formulas, equations, conversions, and practical technical questions without bouncing between separate utilities.

Built-in catalog

Hundreds of ready calculators

Access ready calculators across Geometry, Physics, Chemical, Biological, Construction, IT Infrastructure, Financial, and other industrial profiles next to your own saved tools.

Reference workflows

Materials and local data

Browse local reference data for materials, substances, and elements, then add custom materials for internal or project-specific workflows.

Workspace continuity

Saved state that stays with you

Keep favorites, history, calculations, and workspace preferences locally, then back up or restore them across devices when needed.

Desktop-ready

Flexible windows and layout

Use movable and resizable windows on larger screens and shape the dashboard around the way you actually work.

Ownership

Control without subscription pressure

MicroCAS follows a one-time purchase model and keeps core data on your device unless you explicitly decide to export or share it.

Who it is for

Made for technical users who need reliable local tools

MicroCAS fits engineers, technicians, consultants, estimators, students, researchers, and advanced technical users who need practical local tools for recurring work, field situations, secure environments, or offline travel.

Privacy and control

Local-first by default

No account is required for core usage. Core workflows are designed to stay on the device, and your workspace remains private unless you explicitly export, import, migrate, or share content yourself.

MicroCAS is an assistive professional tool. Results, formulas, references, and user-generated tools should always be reviewed and independently verified before being used in critical engineering, safety, regulatory, legal, medical, financial, or contractual decisions.
