Peter Steinberger says an AI agent loop moved OpenClaw's web frontend from Lit to Solid 2.0 in about two weeks and roughly 600 pull requests
Two weeks ago I kicked off a loop to move OpenClaw's Lit-based Web frontend to Solid 2.0. Took ~6 days until we could remove Lit, and another week to move patterns to idiomatic Solid. I checked in with the session every other day, overall the process was mostly automatic. Took about ~600 PRs. Result: Smaller JS and CSS footprint and much more fine-grained update control. Everything feeling more snappy and responsive.
Context
It is a concrete account of agents doing a large framework migration with little supervision, a task that usually takes teams months.
Peter Steinberger created OpenClaw, an open source AI agent project. This is his own account of a migration, and the figures come from him.
Deep dive
On October 20, Peter Steinberger posted that two weeks ago he kicked off a loop to move OpenClaw's Lit based web frontend to Solid 2.0. Lit and Solid are frameworks for building web interfaces.
He said it took about six days until Lit could be removed, and another week to move patterns to idiomatic Solid. He checked in with the session every other day, said the process was mostly automatic, and that it took about 600 pull requests. The result, he said, was a smaller JavaScript and CSS footprint and much finer grained update control, with everything feeling more snappy and responsive.
The screenshot shows a report generated in OpenClaw's own chat tool, using GPT 6.1 Sol according to the interface. It counts 255 named migration pull requests and the number of interface files importing Lit falling from 796 to 0, with activity peaking at 92 pull requests on October 16.
Steinberger did not say how much human review the changes received or whether bugs appeared afterward. The same day he posted that OpenClaw had moved to tsrs, a new TypeScript compiler.
What to expect next
Watch for OpenClaw users to report whether the new frontend is faster and stable after the migration. Other teams trying similar agent run migrations will show whether this approach works beyond one project. Also watch for Steinberger to share more about how much human review the roughly 600 pull requests received. Solid's maintainers may also comment on the result, since Solid 2.0 is new.
