Sideline is a hosted work-management platform for agencies handling ongoing client requests, retainers, subscriptions, and support agreements. It is aimed at web studios, productized agencies, creative and marketing agencies, client support desks, white-label delivery teams, and freelancer-run agencies. Requests can arrive through custom intake forms or email, then move through queues with statuses, owners, priorities, and due dates. Client portals provide request visibility through magic-link access, while list, board, and calendar views support day-to-day coordination.

Its strongest fit is an agency operating model built around recurring service work rather than project timelines. Sideline supports unlimited clients and client users on the Studio plan, along with unlimited requests and custom intake forms. Time can be tracked per request, person, and client, while reports and CSV export support operational review. Retainer management covers monthly allowances and prepaid hour blocks, making the product relevant to teams that need to connect incoming work with agreed service capacity. The Founding Agency Pass is listed at $999 one-time for three years of everything, with 10 seats, free migration, every future plan included, and a locked 50%-off-forever rate after three years.

Sideline also suits teams building an automation-oriented workflow. AI connectors and MCP access support Claude, ChatGPT, Make, and Zapier, and the integrations list includes Claude Code. Internal notes and content-free email notifications help separate client communication from team coordination. A 14-day free trial provides a defined evaluation window, but there is no free plan. The product is less suitable for teams that require timeline views, resource planning, or broader portfolio scheduling. Agencies centered on queues, retainers, client visibility, and service requests should find the feature set closely aligned; teams managing complex capacity plans should choose a tool with those planning capabilities.
