Summit has everything you need to build, launch, and host your app.
A visual coding environment
The foundation of the Summit platform is a visual code editor, enabling the creation of calculators, forecasts, and simulations that match your vision. Don't settle for a generic widget. Build an app that's custom-tailored to your specific market, brand, solutions, and product offerings.
Easy-to-use, spreadsheet-like syntax for representing almost anything, from simple arithmetic to complex simulations.
Add charts, input fields, defaults, colors, and custom formatting with a simple, familiar interface.
Ready to launch? Ship a stable copy of your app while continuing to experiment and develop updates.
Hosting & API access
After launching, Summit hosts your public and private apps, including an API endpoint to run the app remotely.
Why makers love Summit
Building complex, time-based models is easier in Summit than anything else I've ever used, especially raw code.
Aaron Francis, Marketing Engineer
Succinct, powerful, and expressive
Meet SEL (Summit Event Language), a tiny but powerful language that puts the power of simulation at the fingertips of anyone that can use a spreadsheet. With a simple, declarative syntax, Summit developers can define the small parts of any system or calculation. Click 'Run' and your simulation comes to life, making light work of the most daunting algebra, word problems, and models.
An API for every app
Deploying an app in Summit isn't the end of the road. Two clicks exposes a secure, token-based endpoint that takes the parameters of your app and returns results in JSON format. Call your app with dynamic inputs from any other code or low-code web application.
Summit speaks calendar and time-based functions fluently. Instantly calculate anything that repeats at any frequency. Don't miscalculate a February ever again.
Low-code, low maintenance
Because Summit's scripting language is accessible for spreadsheet users, updates and changes can be made with zero engineering involvement. Need to update the numbers, rates, or assumptions of your app? Click, edit, and re-deploy.
Commit, clone, and revert
Every Summit app uses git-style version history and commits to ensure that your end users and API calls are working against a stable code base. Makers can experiment, revert, and clone their apps with no interruption in service.
Your Low-Code Canvas
for Numerical Data
A Whiteboard That Does Math
Summit unlocks your spatial reasoning. Describe complex calculations as easily as drawing boxes and arrows.
Our world is full of cycles, constraints, and feedback loops. Thanks to its simulator core, Summit handles these with ease.
Growth, Linear and Exponential
Forecasting is second-nature thanks to Summit's simple syntax for compounding, linear, accelerating, and decelerating growth rates.
Stay in the Flow
As you make changes to your formulas, a data table automatically updates with the output of your app.
Time is the X-Axis
Time is a native dimension of all Summit apps. Effortlessly chart, group, and sort your output by any time interval.
Sync with Remote Datasets
Insert data from a connected data source by typing a dollar-sign into any of your calculations.
Structure that Communicates
Unlike spreadsheets and text-based code, Summit's visual editor brings the formulas and functions of your model to the surface, keeping it legible and extensible.
Summit's editor includes a growing list of keyboard shortcuts to make common actions instantaneous.
What Makers Are Saying About Summit
Summit really makes sense. It's a no code way to build data apps. Define the logic on the board, then you can render the layout which ever way you like.
Really admire the modeling tool that Matt is building at @usesummit
Proud user of @usesummit here. Congrats on the launch
Spinning up "simple" models in @usesummit is seriously so awesome. Nothing else like it!
Loving the power and flexibility you’re building into Summit!
Gotta say, getting SignWell lead data coming in with metered pricing automatically calculated by the @usesummit API is veeery cool
I just visited Summit for the first time 🤯
I just started playing with @usesummit and it is a remarkable piece of software. It's the first "spreadsheet replacement" (and graphical programming language) I've tried where it's not just cool but obviously useful, generative, and better at (some) things
This is an incredible product. Easily the most interesting piece of software I know of being built and I am loving following along as it develops.
Damn imagine if MS had done this decades ago! I love how the product is becoming a true powerhouse.

This looks amazing. Just signed up
I’m really enjoying exploring what an app developer experience for @usesummit could be. Adding model-based features to an app or site just got a lot easier
Have been playing with Summit and my head has exploded.
