Charities are being offered grants of up to £70,000 to develop their digital services as part of £1m of new funding.
The grant-makers, the Paul Hamlyn Foundation and Comic Relief, are opening the latest round in the Tech for Good programme.
The scheme was first developed in 2016 to help charities use technology to explore different approaches to delivering their services.
UK charities with annual incomes of between £75,000 and £10m are eligible to apply for the funds, which will be available over a nine-month period from June. Applications close 12 February.
