StateSync is an alternative to Serena
StateSync vs Serena
Serena gives the agent language server tools to read and edit code by symbol. StateSync maps the project in the background, and the agent finishes in fewer, shorter requests.

Where StateSync wins
Savings everywhere, not in one place.
Serena only changes how the agent reads and edits code. StateSync saves on shell output and on finding code, and the agent finishes in fewer, shorter requests.
Nothing to tune.
Serena adds its own set of tools, and its docs ask you to turn off the agent's overlapping ones to keep the context down. StateSync is set up for you.
Hit a limit, keep going.
Move the conversation to another agent or account mid-task, with the same history. Serena has nothing like it.
Side by side
Pick Serena if you want free, symbol-level edits across 40+ languages, or work in JetBrains IDEs.

Can I use StateSync and Serena together?
We have not tested them together. Both help the agent find code, so that saving overlaps. StateSync's other savings would add on top.
Is Serena free?
Yes, under GPL 3.0, with a paid JetBrains backend. StateSync is from $8 a month, with 7 days free.

Serena's figures are its own and its testers', as published. StateSync's come from our own run on one model, so the two were not measured the same way.
