Liquid Logic Builder

About the Liquid Logic Builder

A free drag-and-drop builder for composing full Braze Liquid templates block-by-block. Stack filter chains, add variables and fallbacks, see the rendered output live with editable sample data. For when a one-line snippet isn't enough — personalized sentences, multi-variable templates, nested filter pipelines.

How to use

1. Load a preset that's close to what you want, or start blank.
2. Add variable blocks for each attribute, text blocks for the prose in between.
3. Chain filters on each variable (capitalize, truncate, default, date formatting, etc.).
4. Edit the sample data panel to test your template against realistic inputs.
5. Copy the generated Liquid into Braze, Shopify, or any Liquid-compatible platform.

Common use cases

• Writing multi-variable personalized opening lines ("Hi {first_name}, your {plan} plan renews {date}")
• Composing countdown timers with math filter chains
• Building URL-safe tracking parameters with url_encode
• Composing HTML-safe content blocks that gracefully handle missing data
• Rapid prototyping of new lifecycle templates before committing to Braze

Who it's for

Lifecycle marketers and Braze operators who compose Liquid more than once a week. If you're copy-pasting from the syntax generator into a text editor to assemble full templates, the builder is for you.

Frequently asked questions

How is this different from the Liquid Syntax Generator?

The Syntax Generator is a fast lookup — one variable, one filter, copy the snippet. The Logic Builder composes full templates: multiple variables, chained filters, fallbacks, and a live preview against sample data. Use the generator for one-off snippets, the builder for anything with more than one moving part.

Does the preview use real Liquid?

Yes — the preview runs your compiled template through LiquidJS (an open-source Liquid parser) against your sample data. What you see in the preview is what Braze will render at send time, given the same inputs.

Can I chain multiple filters?

Yes — filters run left-to-right on each variable block. { var | strip | downcase | capitalize } cleans whitespace, normalizes case, and title-cases the first letter, in that order.

Does this support Braze's Connected Content?

Not in Phase 1. This is a template composer for the Liquid expression layer (variables + filters + fallbacks). Connected Content (API calls, external data fetches) requires control-flow and tag support that's planned for Phase 2.

Does this work for Shopify Liquid or Jekyll?

The output is standard Liquid — works on any platform that implements it. A few filters (date formatting, custom_attribute syntax) are Braze-flavored but map cleanly to Shopify/Jekyll equivalents.

  Liquid for lifecycle marketers — the complete Braze reference

  Every personalised field in every Braze message runs through Liquid. Get it right and personalisation quietly improves every send. Get it wrong and 50,000 people see 'Hi {{${first_name}}}'. This reference covers the syntax and the production habits that stop that happening.

  Progressive profiling: asking users for data without scaring them off

  Progressive profiling means collecting user data over time in small, contextual prompts instead of one giant signup form. Done well, it transforms personalisation data quality. Done badly, it's irritating surveillance with extra steps.

  Custom attributes: the data design that decides what your program can do

  Custom attributes are infrastructure. Designed well, they enable every future campaign. Designed badly, they become the reason 'can we segment on X?' is a multi-week engineering project instead of a 15-minute one. Here's the design discipline that prevents the mess.
