Every AI coding tool I tried solved one slice of the workday and ignored the rest. One app for chat, another for the editor, a browser tab for the agent, a terminal off to the side, and a subscription for each. The tools were good. The seams between them were not.
CodeSplash started from a simple frustration: I wanted my entire dev workday in one desktop — the editor, the terminal, git, search, files, and as many AI agents as I wanted to run in parallel, without paying a new subscription for every model.
The problem with fragmented tools
The cost of fragmentation isn't the price of the subscriptions. It's the context you lose every time you cross a seam:
- You copy code out of a chat window and lose where it came from.
- You run an agent, then can't see the files it touched without switching apps.
- You want two agents working at once and there's nowhere to put them.
Each jump is small. Together they add up to a workday that feels busy but moves slowly.
What CodeSplash does differently
CodeSplash is a single desktop app that brings the pieces together:
- Bring your own AI. Connect the accounts you already pay for — no extra AI subscription layered on top.
- Run agents in parallel. Spin up multiple agents at once and watch their work in real integrated apps, not a chat transcript.
- Own it once. A free tier, a 14-day Pro trial, and a one-time $49 Pro license instead of another recurring bill.
The goal is boring in the best way: fewer seams, more flow.
What this blog is for
I'm going to build CodeSplash in the open here — why it's designed the way it is, how it compares to other tools, what ships in each release, and the broader AI-engineering ideas behind it. If that's your kind of thing, subscribe below and I'll send new posts as they land.
