ActiveCampaign alternatives: 7 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
The full automation engine with no contact tax; it replaces the SaaS bill with serious server maintenance.
licenseGPL-3.0+
runsyour server
installDownload the production package or install with Composer, then configure PHP, a database, cron, and a mail transport
dataContacts, segments, campaigns, events, and reports live in the configured MySQL or MariaDB database; assets, configuration, logs, and queue files live on the server filesystem.
vs ActiveCampaignMautic can match deep automation, but the user must operate the application, database, cron, upgrades, backups, mail transport, and deliverability stack.
setupThe first wall is not the installer but production operation: PHP and database tuning, several cron jobs, HTTPS, backups, upgrades, SMTP/API sending, and DNS authentication.

Campaigns, transactional mail and workflows in one container; the sending provider still sends a bill.
licenseAGPL-3.0
runsyour machine or their cloud
installHosted signup, or the official Docker Compose stack
dataThe self-hosted stack stores core data in PostgreSQL, jobs and cache in Redis, and objects in MinIO; hosted data is kept in Plunk's EU infrastructure.
vs ActiveCampaignPlunk is developer-first and much thinner in visual audience management, CRM depth, segmentation tooling, and marketer-oriented reporting.
setupHosted use still needs domain authentication; self-hosting adds PostgreSQL, Redis, MinIO, Nginx or another proxy, exposed web and SMTP services, DNS, and ongoing deliverability work.

Visual campaigns and automations in one modern compose stack; PostgreSQL and an SMTP provider still need seats.
licenseAGPL-3.0
runsyour machine or their cloud
installHosted signup, or one application container plus PostgreSQL for self-hosting
dataSelf-hosted contacts, campaigns, automations, and events live in PostgreSQL; files can use S3-compatible storage, and the configured email provider receives message payloads. Hosted data lives in Notifuse's cloud.
vs ActiveCampaignNotifuse is newer and narrower, without ActiveCampaign's mature CRM, predictive features, and thousand-plus integration ecosystem.
setupSelf-hosting still needs Docker, PostgreSQL, a public HTTPS endpoint, an SMTP or API sending provider, and correctly authenticated sending domains.

Campaigns and automation for up to 2,000 automated contacts; the 300-email daily ceiling slows launch day.
licenseproprietary, free
runstheir cloud
installHosted signup, sender verification, and optional domain authentication
dataContacts, campaigns, templates, automation events, and reports live in Brevo's cloud; exports are available, but the internal storage format is not disclosed.
vs ActiveCampaignThe 300-email daily limit can split even a small launch across days, and only 2,000 contacts can enter automations on the free plan.
setupThe first meaningful hurdle is verifying the sender and setting SPF/DKIM records for a sending domain; without that, deliverability will disappoint.

A useful hosted list plus three five-step automations; exactly enough machinery for a small lifecycle.
licenseproprietary, free
runstheir cloud
installHosted signup, list import, and sender/domain verification
dataSubscribers, campaigns, forms, automation state, and reports live in EmailOctopus's cloud; CSV import/export is supported, while the internal storage format is not disclosed.
vs ActiveCampaignIts automations are intentionally lightweight and do not approach ActiveCampaign's branching logic, goals, CRM integrations, or sales workflows.
setupA sender address must be verified, and serious sending should use an authenticated domain.

Lifecycle and marketing email for 1,000 contacts with every feature; contact 1,001 brings a card reader.
licenseproprietary, free
runstheir cloud
installHosted signup, domain authentication, and event/API integration for lifecycle email
dataContacts, events, templates, and campaign or loop state live in Loops's cloud; the internal storage format is not disclosed.
vs ActiveCampaignLoops is an email-lifecycle tool rather than a sales-and-marketing CRM, so it does not replace ActiveCampaign's deal, account, and broad automation ecosystem.
setupMarketing broadcasts are easy, but lifecycle automation becomes useful only after a non-expert authenticates a domain and connects product events through an integration or API.

A real free list, unlimited workflows and 15,000 monthly sends; SMS did not make the cut.
licenseproprietary, free
runstheir cloud
installHosted signup, list import, and sender/domain verification
dataSubscribers, campaigns, forms, automation state, transactional messages, and analytics live in Sender's cloud; the internal storage format is not disclosed.
vs ActiveCampaignSender covers email automation but not ActiveCampaign's sales CRM, deal records, lead scoring, or broad sales-automation layer.
setupThe first real hurdle is authenticating the sending domain and warming a legitimate list rather than merely creating the account.

People still pay for ActiveCampaign because newsletter operators pay for inbox placement, growth mechanics, and operational confidence on publication day. The recurring cost buys DNS authentication, reputation, bounces, complaints, unsubscribe compliance, templates, queues, analytics, backups, and support, not just the visible interface. If none of that applies to you, any pick above saves $180 a year.
Is there a free alternative to ActiveCampaign?
Yes: Mautic, Plunk, Notifuse and 4 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own ActiveCampaign?
Our verdict is NOT REALLY. A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For ActiveCampaign, run a small email list and a handful of transparent automations. The hard boundary is deep lifecycle automation, crm, deliverability, integrations, and data history, plus deliverability, growth network, and integrations. If you'd rather build, the exact one-shot prompt is free at canivibecodeit.com/activecampaign.
