What Makes a Coding Agent Trustworthy? A Look at SolonCode's Design Choices
Every week there's a new coding agent, and every week someone asks the same question in a slightly different tone: can I actually trust this thing with my codebase?

It's a fair question. A coding agent reads
It's a fair question. A coding agent reads your source, runs commands in your shell, and — increasingly — edits files and opens pull requests on its own. That's a lot of access to hand to a black box. So instead of arguing about which agent is "smartest," I want to talk about a less glamorous property: trust. What does it actually take for a coding agent to earn it?
I'll use SolonCode — an open-source coding agent
I'll use SolonCode — an open-source coding agent built in Java on top of Solon AI — as a concrete reference, not because it's the only good answer, but because its design happens to line up with a checklist I think is worth having. Take the checklist with you and hold any agent to it, including this one. A trust checklist for coding agents Here are the five questions I ask before I let an agent near a real repo. 1. Can I read the source?
The strongest form of trust is the kind
The strongest form of trust is the kind you don't have to take on faith. If the agent is open source, you (or your security team) can read exactly how it builds prompts, what it sends over the wire, and where it stores things.
SolonCode is MIT-licensed and fully open source
SolonCode is MIT-licensed and fully open source — the CLI, the Web UI, and the desktop client are all in the open. That means the interesting questions ("what exactly gets sent to the model?", "does it phone home?") are answerable by reading code, not by trusting a marketing page.
This is the part that "purity" really comes
This is the part that "purity" really comes down to for me: not a vibe, but the fact that there's nothing you can't look at. 2. Where does my code go?
A coding agent has to send something to
A coding agent has to send something to a model to be useful. The question is what else happens along the way — telemetry, analytics, background uploads. SolonCode runs locally. You start it from your own machine in whichever form you like:
The agent process lives on your box, works
The agent process lives on your box, works in your workspace, and talks directly to the model endpoint you configured. There's no mandatory middle-tier service that your code has to pass through first. For teams with source that legally cannot leave the building, that distinction is the whole ballgame. 3. Am I locked into one vendor?
A lot of agents are welded to a
A lot of agents are welded to a single model provider. That's convenient right up until pricing changes, a better model ships elsewhere, or your employer mandates a specific vendor.
SolonCode is provider-agnostic. You configure models yourself
SolonCode is provider-agnostic. You configure models yourself — through Settings → LLM in the Web UI — and point it at whatever you're allowed to use: a hosted API, an OpenAI-compatible endpoint, or a local model. Because it's built on Solon AI, swapping the underlying model is a configuration change, not a migration. The practical value: the day a cheaper or smarter model shows up, you switch a setting instead of switching tools. 4. Can I control what it does?
