NIELLO Dex / Developer Empowered Experience
Every agent you already use.
One place to run them well.
One place for developers to run, govern and hand off work across the coding agents they already use — such as Claude Code, Codex and Gemini CLI — in a terminal-first workspace.
Explore DexEvery agent you already use.
$ dex doctor
ok harness registry 2 can host a governed session
(claude, codex)
FAIL harness gemini no hook installer — a session
here would run uninstrumented
fix: use a governable harness, or `start --force`
to run this one uninstrumentedTHE AGENT WORKBENCH
Every agent you use. One governed place.
Pick a session, see what the gate allows, refuses or holds, and continue the work with another agent.
A scripted rendition of the Dex app with example data. Nothing here runs an agent, calls a model or enforces a policy.
01 / Check the machine first. dex doctor finds the agents installed here, says which can run governed and prints the fix for every gap.
~/acme/storefront $ dex doctor
dex — boundary report
1 check needs attention (see fix: lines above).

Claude Code → Codex
The conversation and its lineage travel with the work.
MADE TO MOVE YOU FORWARD
A clearer purpose.
A more powerful possibility.
Every agent, in one place
See the agents and sessions on a machine, start them from one workspace and check their health with a single doctor command that names every fix.
Governed, and honest about it
A deterministic policy gate runs before tools execute and fails closed. An agent cannot edit its own gate, and a session is never shown as governed when it is not.
Continue with another agent
Continue a Claude Code session in Codex or Gemini CLI with its conversation and lineage intact, and keep a receipt of what changed in each pull request.

BETTER, CONNECTED
Dex is only the beginning.
A LITTLE MORE CLARITY
Good questions.
Clear answers.
How do we begin with Dex?
Bring a concrete use case to a discovery conversation. We will map how Dex fits the workflow, confirm the systems and access it needs, and agree on what a useful pilot should demonstrate.
Can we keep our existing systems?
The platform is designed to work with your systems and chosen model providers. Connector availability, infrastructure boundaries and data requirements are confirmed when scoping your deployment.
How is availability confirmed?
The site describes the Niello product direction. Specific features, integrations, deployment options and commercial terms are confirmed with your team before an engagement begins.
