About the project
Z3 is an open-source SMT solver (theorem prover) from Microsoft Research that checks satisfiability of logical formulas and proves theorems. It is used for formal verification, symbolic execution, and optimization problems.
Useful for
- Verify algorithm correctness through formal verification of conditions
- Solve a scheduling or planning problem encoded as an SMT formula
- Embed the solver into your tool via C++, Python, or .NET bindings

Star growth looks organic. Data as of November 2, 2026, 21:46 UTC.
The star-growth assessment does not verify whether the project is safe to run.
Stars per day
Bars show stars per UTC day; the line is a moving average of available history. Gaps mean missing data, not zero growth. Today's bar is incomplete. Red marks spike days.
Why it’s trending
- Star-counter measurements on 2026-11-02 (UTC), 00:16–21:43: 12870 → 12873 stars (+3). This is the change over that interval.
- Estimated end-of-day forecast: about +3 stars, using observed gains and the previous day.
Measured growth: the last 7 completed days
New stars over 7 days: 40. -15% versus the preceding 7 days.

Star trust
Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.
These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
