# Open SaaS Alternatives > A directory of open-source and licence-free software a small business can run instead of paying a per-seat SaaS bill. Scores use public repository signals. Unknown figures are left blank. The site is not affiliated with the SaaS products it names. Last updated: 15 Oct 2026. Repository figures were captured on 2026-10-15 (GitHub REST API + LICENSE files read 2026-10-15; releases from releases.atom; docker/ci from raw file HEAD; OpenSSF Scorecard where the project was in the dataset.). ## Key facts - Site: https://opensaasalternatives.com/ - 15 categories, 81 apps, 31 named SaaS products used as the job to replace. - Score weights: Alive 20, Trusted 20, Takeoverable 25, Easy to run 20, Feature fit 15. Unmeasured signals are omitted. They are not scored as zero and the remaining points are not scaled up to 100. - An archived repository forces the Alive pillar to 0. - SeatLess apps use the same formula. They have no public repository, so GitHub health points are omitted, and they are not pinned to the top. - Most incumbent list prices are not stored. The 3-year calculator uses the price on the visitor’s invoice. SaaS bill = seats × monthly price × 36. Owned = setup + (hosting + upkeep) × 36. The large number is the difference. - Docker is mentioned only when the repository contains a production Dockerfile or Compose file. Done-for-you setup by SeatLess is offered on every app and labelled as such. - Full catalogue: https://opensaasalternatives.com/llms-full.txt - Scoring formula: https://opensaasalternatives.com/methodology/ - Disclosure: https://opensaasalternatives.com/disclosure/ ## Categories - [E-signature](https://opensaasalternatives.com/category/e-signature/): Tools that replace a DocuSign or PandaDoc subscription: send a document, collect signatures, and keep the audit trail on a system you can host. Highest measured score: Documenso (49). - [Scheduling](https://opensaasalternatives.com/category/scheduling/): Booking pages and group polls that replace a Calendly seat. Some are full booking links. Some only help a group pick a time. The listing says which is which. Highest measured score: Cal.com (52). - [Forms and surveys](https://opensaasalternatives.com/category/forms-surveys/): Forms and surveys that replace Typeform, Jotform, or SurveyMonkey. Conversational bots and classic survey servers are both listed, with the licence spelled out. Highest measured score: Formbricks (48). - [CRM](https://opensaasalternatives.com/category/crm/): Contact and pipeline systems that replace Pipedrive, HubSpot, or Salesforce seats. You host the database, so the customer list is not stuck in someone else’s account. Highest measured score: EspoCRM (51). - [Helpdesk and live chat](https://opensaasalternatives.com/category/helpdesk-live-chat/): Shared inboxes, ticket queues, and live chat that replace Zendesk, Help Scout, or Intercom. IT asset systems are labelled as such, so you do not buy a service desk when you wanted a shared inbox. Highest measured score: Chatwoot (53). - [Project management](https://opensaasalternatives.com/category/project-management/): Boards and project systems that replace Trello, Asana, or Monday. Kanban tools and full project suites are both here. The quiet ones are marked from their release history. Highest measured score: Kanboard (55). - [Docs and wiki](https://opensaasalternatives.com/category/docs-wiki/): Wikis and note systems that replace Notion or Confluence. A few use source-available licences. Those carry a Caution badge so the paperwork is visible before you migrate. Highest measured score: BookStack (56). - [Screen recording](https://opensaasalternatives.com/category/screen-recording/): Recorders that replace a Loom seat. One is a shareable web recorder. The others are desktop or browser tools. They do not all give you a hosted watch-page. Highest measured score: Cap (47). - [Email marketing](https://opensaasalternatives.com/category/email-marketing/): Mailers that replace Mailchimp. Some send straightforward newsletters. Mautic is closer to full marketing automation. You still bring your own sending domain. Highest measured score: Mautic (54). - [Courses and LMS](https://opensaasalternatives.com/category/courses-lms/): Learning systems that replace Kajabi or Thinkific for the course itself. They are classrooms, not marketing sites. You still need somewhere to sell, if selling is the job. Highest measured score: Moodle (48). - [Team chat](https://opensaasalternatives.com/category/team-chat/): Chat servers that replace Slack. Element is a Matrix client: you also need a homeserver. Stoat is the project previously known as Revolt. Highest measured score: Rocket.Chat (58). - [Web analytics](https://opensaasalternatives.com/category/web-analytics/): Analytics you host yourself, in place of Google Analytics or Mixpanel. Cookie-light site stats and fuller product analytics are listed separately. Highest measured score: Umami (56). - [Automation and internal tools](https://opensaasalternatives.com/category/automation-internal-tools/): Workflow tools that replace Zapier, and internal-app builders that replace Retool. Airtable-style databases are included and labelled. Highest measured score: Appsmith (58). - [Invoicing](https://opensaasalternatives.com/category/invoicing/): Invoicing and small ERP systems that replace FreshBooks or Zoho Invoice. Read the licence: two popular projects are source-available, and one has not tagged a release since 2022. Highest measured score: SolidInvoice (50). - [Meetings and scorecards](https://opensaasalternatives.com/category/meetings-eos-scorecards/): Tools in the neighbourhood of Ninety.io and EOS One: goals, weekly meetings, and boards. This category is thinner than the others. If you run a proper L10, tell us what you use. Highest measured score: OpenProject (51). ## Alternatives to a named product Wording is “replaces {product}”. That describes the job, not a partnership. - [DocuSign](https://opensaasalternatives.com/alternatives/docusign/): Docusign. Highest measured score: Documenso (49). - [PandaDoc](https://opensaasalternatives.com/alternatives/pandadoc/): PandaDoc. Highest measured score: Documenso (49). - [Calendly](https://opensaasalternatives.com/alternatives/calendly/): Calendly.
