Charity Engine is a volunteer distributed computing project founded in 2008. It is based on Berkeley University's BOINC software, and has been noted for its contributions to protein folding, and for finding several solutions to the "sum of three cubes" problem.

In early 2022, apgsearch was added to the list of projects Charity Engine conducts. Hauls from the soup searching program are uploaded to Catagolue under the username TechnobladeNeverDies, an account owned by Darren Li, who developed the specific patch to apgsearch that is used on Charity Engine. The network is consistently searching hundreds of billions of soups per day, and TechnobladeNeverDies is currently the most prolific contributor in the history of soup searching. The first hauls from Charity Engine were submitted to Catagolue on January 6, 2022.

Notable discoveries include:

• January–February 2022: record-breaking messless methuselahs in both C1 and C4_4 symmetries
• February 2022: 32P21, then the smallest known period-21 oscillator
• February 2022: a symmetric soup containing a bi-gun, the second unique gun to have occurred semi-naturally
• February 2022: a new period-30 glider gun, which can be monomerized to only contain a single queen bee
• February 2022: 58P8H4V0, the first period-8 spaceship to occur in a random soup
• February 2022: An oscillator comprised of four copies of Silver's p5 hassling a beacon into period-5 instead of their own snakes
• February 2022: A stator variant of an oscillator comprised of two 20P4 halves mutually stabilising a long hat on blocks
• March 2022: A statorless p6 with a different mechanism from the known ones
• March 2022: A glide-symmetric period-4 C4_1 oscillator mutually stabilising four mazing halves
• April 2022: a symmetric soup via apgsearch exhibiting infinite growth whose center takes 225,593,194 generations to stabilize, a new record
• May 2022: 30P25, then the smallest known period-25 oscillator
• May 2022: meatball, a period-7 sparker with some similar functionality to the previously known 38P7.2
• May 2022: A dimer form of the smallest known p6 domino fountain variant
• June 2022: Charity's p16, a period-16 sparker
• July–August 2022: two symmetric soups lasting 128,719 and 132,364 generations respectively before stabilizing, while still meeting the standard definition of a methuselah by eventually ceasing to grow infinitely
• August 2022: 34P7, a period-7 sparker similar to meatball but smaller in terms of population
• August 2022: p11 thumb, the first period-11 oscillator with an asymmetric rotor to appear in an official Catagolue symmetry
• September 2022: A p12 c/2 spaceship comprised of two LWSSs stabilising two b-heptominoes mutually supporting an unnamed region behind them, the first p12 spaceship not based on the Schick engine to occur seminaturally
• October 2022: p28 block puffer, a semi-natural linear growth mechanism a la the pufferfish
• October 2022: 34P20, the smallest known non-LCM-based period-20 oscillator
• October 2022: A glide-symmetric period-14 C4_1 oscillator that uses the block on table as a rock
• January 2023: A D8_1 p18 honey farm hassler, later monomerised (explained in its article)
• January 2023: Charity's p25, the first known strictly volatile period-25 oscillator
• January 2023: Charity's p30, a gutter-symmetric period-30 oscillator originally in tetramer form
• January 2023: Glider-pair-eating constellation that allows the stabilisation of the period-156 glider gun to an oscillator with the highest known volatility of any of its variants (found covering two barrels)
• November 2023: The new longest-living natural diehard.

Notable occurrences (semi-natural unless specified otherwise) of previously-known objects include:

• February 2022: Merzenich's p64
• February 2022: Big A
• February 2022: Bi-gun
• February 2022: A dimer of the overweight emulator
• March 2022: a symmetric soup containing a pair of darts, making it the first period-3 spaceship to occur semi-naturally
• March 2022: A D4_+2 variant of the pentadecathlon on snacker
• April 2022: a symmetric soup containing two copies of 44P5H2V0, making it the first period-5 spaceship to occur semi-naturally
• April 2022: The four-block variant of the twin bees shuttle in C1
• April 2022: The Eater/block frob in C1
• May 2022: A figure-eight-supported Coe's p8 variant (in D4_x4 dimer form)
• May 2022 and January 2023: A C4_1 variant and D4_x1 variant of the p29 pre-pulsar shuttle
• June 2022: Phoenix with cavity in C1
• July 2022: 37P10.1 tetramer
• September 2022: A twofold variant of the carnival shuttle
• November 2022: A 120P7 variant hassling blinkers
