Softr alternatives: 5 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.
Internal apps, forms, automations, and portals in one box; much closer to Knack than its developer branding suggests.
licenseGPL-3.0
runsyour server
installDocker image or Docker Compose; Kubernetes is also supported
enginesModel-agnostic; the agent builder supports bring-your-own AI provider credentials
dataBuilt-in app data and app definitions are stored in CouchDB, files in MinIO/S3-compatible object storage, and connected external data remains in its source system
the catch vs SoftrIts internal-tool aesthetic and component system are less suitable for polished public portals, directories, and membership sites than Softr.
setupRequires Docker and persistent storage; production use also means owning upgrades, TLS, backups, and database/network access

A database-backed app builder with pages, forms, roles, workflows, and enough plugins to become your next maintenance hobby.
licenseNocoBase Community
runsyour server
installNocoBase CLI or Docker deployment with MySQL, MariaDB, or PostgreSQL
enginesBuilt-in AI employees can connect to common LLMs; exact provider support depends on installed AI plugins
dataBusiness data lives in standard relational tables in the configured MySQL, MariaDB, or PostgreSQL database; files use configured local or object storage
the catch vs SoftrNocoBase trades Softr's hosted visual page building and templates for self-hosted database administration and a more technical plugin model.
setupRequires a database, secrets, and deployment administration; the community license also preserves NocoBase branding and restricts some uses

A sober business-app builder with forms, reports, roles, workflows, and no per-user meter.
licenseMIT
runsyour server
installNative Linux/Windows server package or Docker Compose, connected to PostgreSQL
dataHuman-readable application records and configuration live in a PostgreSQL database controlled by the operator
the catch vs SoftrREI3 can build functional role-aware apps, but its visual design, templates, and external portal experience are much more utilitarian than Softr.
setupYou must provision PostgreSQL and configure a server/reverse proxy; it is not a managed one-click workspace

The database and app builder live together; portals are less polished, but forms, roles, views, and external users are present.
licenseMIT
runstheir cloud
installHosted signup
dataTables, application definitions, uploads, and workspace metadata live in Baserow Cloud; tables can be exported as CSV
setup✓ installs clean
the catch vs SoftrBaserow's app pages are markedly less polished and template-rich for branded client portals than Softr's responsive block library.
facts verified 2026-08-10
The same product's free plan publishes one branded portal with internal and external users, data actions, forms, and workflows.
licenseproprietary, free
runstheir cloud
installHosted signup in Softr Studio
dataApp definitions and any Softr Database records live in Softr's cloud; connected-source records remain in the external source, with Softr proxying requests and caching data for up to 24 hours; table blocks can export CSV or XLSX
the catch vs SoftrIt is the same builder, but the free plan keeps Softr branding and materially tighter limits on published apps, users, records, and advanced controls.
setupNo software install; the first hurdle is choosing and authenticating a data source, then mapping its fields and permissions

They pay so non-engineers can launch portals without hiring a developer. If none of that applies to you, any pick above saves $300 a year.
Is there a free alternative to Softr?
Yes: Budibase, NocoBase, REI3 and 2 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 Softr?
Our verdict is PARCIAL. A client portal over Airtable can be built, but Softr's block library, auth, roles, data sources, payments, and publishing workflow are the product. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/softr.
