Zoho Projects is one of the most popular online project management solutions with mostly positive reviews and great pricing policy based on the number of projects. If you are looking for a free Zoho Projects alternative, Bitrix24 is a great option. For exactly 0 dollars and 0 cents you get unlimited projects, tasks, subtasks and templates. Document management and CRM are also included free of charge, as are unlimited quotes and invoices, in case you want to bill by the hour. Also, unlike Zoho Projects, Bitrix24 is available both in cloud and as self-hosted software that can be installed on your server for on-premise deployment. If you go for the self-hosted option, you get open source code access.
