HubSpot CRM
Broadest free tier; grows into marketing and service
Free plan available
Visit hubspot.comCompared: HubSpot vs PipedriveHubSpot is on this list because its free tier is the most usable free CRM we found, not because it is the cheapest way to end up paying. You get contacts, companies, deals, a pipeline, email tracking and forms without a card, and you can run a real sales process on that for a long time.
It earns its slot for a second reason: it is one record of the customer that marketing and support can both work from later. If you can imagine wanting email campaigns, a help desk or a chat widget attached to the same contact next year, starting here saves you a migration.
Best for a one-to-ten-person business that wants a system of record now and might grow into marketing automation. Worth knowing before you commit: the jump from free to paid tiers is a real step, seats and contact tiers both push the bill, and the features that make HubSpot pleasant tend to sit one tier above the one you are on.
Skip it if you only want a pipeline. HubSpot is broad by design, and you will be paying for — and clicking past — marketing and service tooling you never asked for. A focused CRM will feel faster every day.
