The Evryscopes are a set of rapid-cadence, gigapixel-scale telescopes. Each instrument contains an array of up to 24 camera units, each consisting of a {{Convert|6.1|cm|in|abbr=on}} telescope (85 mm Rokinon DSLR lens) paired to a thermoelectrically cooled astronomical CCD. The camera units are arranged around a solid fiberglass structure to form a continuous field of view of 9216 sq. deg.

The first instrument (Evryscope-South) was deployed in May 2015 to Cerro Tololo Inter-American Observatory, where it is co-located with the PROMPT Telescopes. The second instrument (Evryscope-North) was deployed in October 2018 to Mount Laguna Observatory.

Evryscope detected the first The First Naked-Eye Superflare Detected from Proxima Centauri. In March 2016, the Evryscope observed the first superflare that was visible to the naked eye from Proxima Centauri. Proxima increased in brightness by a factor of roughly 68 times during the superflare and released a bolometric energy of 10^33.5 erg, about 10 times larger than any previously detected flare from Proxima Centauri.{{Cite web |last=Cowing |first=Keith |date=2018-04-09 |title=The First Naked-Eye Superflare Detected from Proxima Centauri |url=https://astrobiology.com/2018/04/the-first-naked-eye-superflare-detected-from-proxima-centauri.html |access-date=2025-04-01 |website=Astrobiology |language=en-US}}

Evryscope-South is funded by NSF/ATI and NSF/CAREER and was designed and built at the University of North Carolina at Chapel Hill. Evryscope-North is funded in collaboration with San Diego State University.

The Argus Array Pathfinder, a technological successor with 38 cameras, was deployed in December 2022 at PARI, North Carolina. It serves as a prototype for the Argus Array, which will be a 900 camera survey instrument and replace the CCD technology with MOSFET detectors.{{Cite web |title=All-seeing telescope will snap exploding stars, may spy a hidden world |url=https://www.science.org/content/article/all-seeing-telescope-will-snap-exploding-stars-may-spy-hidden-world |access-date=2022-08-29 |website=www.science.org |language=en}}{{Cite web |title=The Argus Array |url=https://evryscope.astro.unc.edu/the-argus-array/ |access-date=2022-08-29 |website=The Argus Array & the Evryscopes |language=en-US}}
