Not every problem needs a big application.
Yippify project · Focused Web Applications
Useful Little Tools starts with a practical question: what is the smallest useful tool that could solve this problem? It turns recurring work friction into focused browser applications, then leaves room to learn what deserves to grow.

01The problem
Little sources of friction add up.
Useful Little Tools starts with the everyday problems we keep running into at work: small enough to overlook, frequent enough to interrupt the day.
Each one invites the same question: what is the smallest useful tool that could solve this?
- Calculations repeated by hand
- Commands or syntax that are easy to forget
- Data that is hard to understand
- Reports assembled manually
- Spreadsheets doing jobs they were not designed for
- Workflows with repetitive steps
- Engineering questions that should be easier to answer
A simple need can inherit a lot of software.
When scope outgrows the problem, the software grows with it. Useful Little Tools takes the other route: prove one job is worth solving before adding a platform around it.
- Accounts
- Permissions
- Workspaces
- Dashboards
- Notifications
- Integrations
- Administration
02Simplify
Good engineering means choosing the right amount.
Yippify has the engineering depth to build complex systems when the problem calls for them. It also means knowing when complexity isn’t necessary.
Start with one useful job. Add capability only when real use gives a reason.
Not every problem needs a platform.
A focused version of the same process: understand the problem, build a tiny tool, then learn from its use.
- Problem
- Simplify
- Tiny tool
- Use
- Learn
Small software. Real value. Software isn’t valuable because it has the most features. It matters when it makes something:
- Easier
- Faster
- Clearer
- More reliable
Imagine a focused tool that turns a repetitive ten-minute task into a few seconds—or makes confusing data clear at a glance. Those are useful outcomes, not a promise of measured results.
03Working examples
Small tools for real, specific jobs.
The live catalog groups its tools by category, from developer and engineering tools to cycling and fitness calculators. These examples are grouped by the problems they help with, not as a directory of everything on the site.
Explore Useful Little ToolsFocused by design. Local-first where it fits.
The collection favors lightweight web applications that open quickly, do one job, and explain how they handle your data. Many process working data in the browser; each tool describes its own behavior.
Engineering delivery
Make sprint flow, bottlenecks, and unfinished work easier to see.
Developer & data tools
Developer productivity tools to inspect structures and query behavior without extra setup.
Career, work & calculations
Handle small planning tasks with a tool shaped for that one job.
04Let real use lead
From a tiny tool to a bigger product—only when needed.
A small tool can test whether a problem is real and whether the solution helps. Learn from use before investing in a larger system.
We shouldn’t build 30 features before knowing whether people need the first one.
Grow only when the need is real
This is an optional capability path, not a checklist every tool has to complete.
- Tiny tool
- Real need
- Persistence
- Collaboration
- Automation
- Larger product
Choose the right size of solution.
A few useful questions.
What is an internal tool?
Software built for a team’s own workflows: for example, to collect information, apply business rules, or make an internal process easier to run. It can be a small utility rather than a platform.
When should a company build an internal tool?
Build when a repeated, important workflow is poorly served by existing products and a focused tool is simpler than continuing with manual workarounds. First check whether configuration or a process change would solve it.
When should a spreadsheet become a web application?
Spreadsheet replacement makes sense when multiple people depend on the same file, manual updates create errors, or access, validation, history, and integrations matter. A custom web application can handle those needs; a spreadsheet that is working well does not need replacing.
When should a manual workflow be automated?
Business process automation helps when steps are frequent, stable, and clear enough to describe, especially when handoffs or repeated data entry cause delays. Map exceptions first; automating a confusing process can make the confusion happen faster.
Should every internal tool become a SaaS product?
No. Many tools are valuable precisely because they fit one organization. Consider SaaS only when other users share the problem and the cost of supporting a broader product makes sense.
How complicated does custom software need to be?
Only as complex as the problem requires. Design for the real security, reliability, integration, and change needs, then add architecture and process when they solve a concrete constraint.
When is custom software better than buying another platform?
Custom software can fit better when a core workflow is unique, existing tools leave important gaps, or the workarounds cost more than a focused solution. Compare the full cost of building and maintaining it with buying or improving what you already have.
What’s Your Repetitive Problem?
A small problem can be a good place to start.
If your team repeatedly performs something manually, maintains a complicated spreadsheet, assembles the same report every week, or works around software that doesn’t fit your process, let’s look at whether a focused software solution could make it easier.
- Custom internal tools
- Workflow automation
- Custom dashboards
- Custom reporting tools
- Integrations
- Focused web applications
- Custom business software
Sometimes the right answer is improving the existing process rather than building more software.
