Free, open-source WiFi planner that runs in your browser. Drop a floorplan, place access points from 100+ real models, and see signal coverage through walls in real time. Each wall material has realistic RF attenuation. Glass, brick, concrete all behave differently. Channels are assigned automatically, and a 3-stage optimizer finds ideal AP placement. No account, no install, no subscription.
I kept running into co-channel interference in my apartment and wanted to figure out the best channel assignments without paying for Ekahau. I looked around and everything was either expensive enterprise software or too basic to be useful.
So I built Deconflict. It started as a graph coloring solver for channel assignment, but once I could see the interference graph I wanted to see the actual signal coverage too. That led to wall detection from floorplan images, then per-material RF attenuation (glass vs brick vs concrete), then an AP placement optimizer.
The hardest part was making the heatmap feel right. Real indoor signal propagation is messy. I went through several iterations of the signal model before landing on one that looks physically plausible and runs fast enough to update as you drag APs around. The wall material system made the biggest difference. Seeing your signal actually degrade through a concrete wall differently than a glass door makes the tool genuinely useful for planning.
It's completely free and open source. Everything runs in the browser, nothing hits a server. I use it for my own network and figured others might find it useful too.

Who hunted Deconflict?
Deconflict was hunted by Sean Reid. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
