Hare, who guided the Arrows to a fifth placed finish to the campaign after taking the helm last year, stepped down to concentrate of his family and business commitments, including his work as an FA coach.
Edged out on penalties by Dorking Wanderers in the play-off semi-finals, Hare's side were the highest scorers in the top eight tiers of English football last season with 128 league goals and 150 in all competitions.
Officials at The Pilot Field told fans they understood Hare's reasons for resigning in a statement on Sunday night confirming he'd always be a welcome guest after the service he'd given the Sussex club.
The Arrows said: "Darren has recently been on holiday and the club were aware before his departure that he had some things to think about whilst away not least his family commitments and future career path.
"On his return Darren advised that he wishes to concentrate on committing more time to his family and developing his business through FA coaching work, something that has suffered during 2016-17 due to his commitment to Hastings United FC.
"Although sad to be going Darren feels that he leaves the club with a group of settled players more than capable of getting promotion next season and with some additions to strengthen certain areas he believes the new manager coming in will be able to benefit and take the club forward and achieve that goal.
"Hastings United FC would like to thank Darren for his service and wish both himself and his family all the best for the future. Darren will always be a welcomed visitor to the Pilot Field at any time."
