# OpenWrt Support
We are trying to bring Mimic to OpenWrt. The packaging effort is going on in the [`openwrt` branch](https://github.com/hack3ric/mimic/tree/openwrt), where one can download build artifacts from each commit's [GitHub Actions](https://github.com/hack3ric/mimic/actions/workflows/openwrt.yml), or build it locally according to [OpenWrt documentation](https://openwrt.org/docs/guide-developer/toolchain/single.package).
However, OpenWrt does not come with both kernel BTF and kprobe configuration enabled, and [checksum hacks](checksum-hacks.md) cannot be applied without recompiling the kernel.
As some of the scenarios [does not require checksum hack](checksum-hacks.md#when-is-checksum-hack-not-necessary), we build Mimic on OpenWrt with `CHECKSUM_HACK=kprobe`. You can use Mimic normally without the kernel module using prebuilts, but if you do need the checksum hacks, you have to [build the OpenWrt image manually](https://openwrt.org/docs/guide-developer/toolchain/beginners-build-guide).
