Open-Source Coda AI Alternatives (2027): 7 Self-Hosted Docs and Database Tools With AI, Now That Coda Is Superhuman Docs

Open-Source Coda AI Alternatives: Docs, Tables and AI You Can Host Yourself

Coda made its name as the doc that works like an app: pages, connected tables, formulas, buttons and automations in one place, with Coda AI on top. Grammarly bought it, and in July 2026 it was renamed Superhuman Docs, part of the Superhuman suite that also includes Grammarly. If you would rather own your workspace, keep company data on your own server and choose which AI model reads it, an open-source tool is the way out. We checked every tool below on its official website, pricing page and GitHub in October 2026: the exact licence (open source or only source-available), whether it combines documents with tables the way Coda does, and which AI features really exist, including support for your own API key or a local model. Tools that are not open source, and the picks from the old version of this list that do not replace Coda, are listed separately at the end.
Quick answer: for the closest Coda-style mix of docs and databases with AI, use AppFlowy or AFFiNE; if what you love about Coda is its formulas and table logic, use Grist; for tables plus apps and automations with an AI field, use Baserow; for a private, local-first knowledge base with AI chat, use SiYuan; and for a team wiki, use Docmost (its AI is on the paid plan).

What Happened to Coda, and What Coda AI Costs in 2027

Grammarly announced that it was buying Coda in December 2024, and Coda's co-founder Shishir Mehrotra became Grammarly's CEO. The company now uses the Superhuman name for its suite of Grammarly, Superhuman Mail, Superhuman Go and Docs, and on 8 July 2026 it renamed Coda to Superhuman Docs. Existing Coda docs moved over automatically, and the company said prices would not change. The launch added Docs AI that builds trackers and workflows inside a doc, an MCP server for everyone so Claude, ChatGPT or Cursor can work with your docs, and AI Views and Superhuman Databases in closed beta.
On the Superhuman Docs pricing page (default view, checked October 2026, prices shown in euros from the Netherlands), the Free plan includes collaborative docs, connected tables, formulas and automations, and a trial of Docs AI and MCP. Pro costs €12 per Doc Maker per month billed annually (€15 monthly) and adds unlimited doc size and AI that writes, edits, answers and builds trackers and views. Business costs €33 per Doc Maker per month billed annually (€40 monthly) and adds Databases and unlimited automations. Docs AI is in beta and available to Doc Makers. You pay per Doc Maker, not per reader, which keeps Coda cheap for teams where few people build docs. Every tool below can be self-hosted for free; you pay for the server, your own time and, if you want AI, your model provider.

The Best Open-Source Coda AI Alternatives in 2027

1. AppFlowy: docs, databases and AI, also with self-hosted models

AppFlowy is the closest open-source match to a Coda workspace: pages and wikis sit next to databases with grid, board and calendar views, so a project tracker and its brief live together. Its AI covers a writing assistant, an AI chatbot, AI search grounded in your own pages and AI meeting notes, and AppFlowy says you can power it with self-hosted LLMs and embedding models. The desktop and mobile apps are AGPL-3.0. Two things to know: on the AppFlowy pricing page the free Personal plan lists its AI features as a limited trial, while Pro costs $12 per member per month billed annually ($16 monthly); and the open-source AppFlowy Cloud server was archived in September 2026. Self-hosting now uses a closed-source commercial server whose free tier covers one user seat and up to 3 guest editors. Version 0.14.11 came out in October 2026.

2. AFFiNE: docs, whiteboards and databases in one place

AFFiNE describes itself as a workspace with fully merged docs, whiteboards and databases, which suits founders who plan visually as well as in text. Its AI add-on costs $8.9 a month billed annually on the AFFiNE pricing page and writes and rewrites text, turns outlines into mind maps and drafts presentations (beta). If you self-host, the AFFiNE self-hosting AI guide lets each workspace bring its own key for OpenAI, Anthropic, Gemini or FAL, and an admin can allow custom OpenAI-compatible endpoints. The cloud has a free plan for up to 3 members per workspace, Team costs $10 per seat per month, and the self-hosted FOSS edition is free. Its code is MIT-licensed outside the backend, which carries its own licence. The latest stable release is 0.27.4 from August 2026, with daily canary builds.

3. Grist: formulas and table logic, with an AI formula assistant

Grist is the best pick if Coda's formula language is what you rely on. Grist calls itself a modern relational spreadsheet: typed columns, formulas written in Python with many Excel functions, linked widgets that show related records side by side, cards, charts, calendars and native forms. The grist-core repository is Apache-2.0 and its AI Formula Assistant works with OpenAI, Llama and other models through OpenRouter or any OpenAI-compatible endpoint, so you can keep AI on your own server. An MCP server for Claude or ChatGPT is part of the full edition, not grist-core; if you want only open-source code, use the grist-oss Docker image. Version 1.7.22 came out in October 2026.

4. Baserow: tables, apps and automations with an AI field

Baserow covers the app side of Coda: databases, an application builder, dashboards and automations. Its AI field fills a column from a prompt, and Kuma, its AI assistant, builds tables, views, fields and formulas from a description. When you self-host, you can connect OpenAI, Anthropic, Ollama, OpenRouter or Mistral. On the Baserow pricing page the cloud Free plan covers 3,000 rows and 2 GB per workspace and 2,000 automation credits a month, while AI features come with Premium at $10 per user per month billed yearly ($12 monthly). The core is MIT-licensed, and premium features sit in separate folders. It has no rich doc pages, so pair it with a wiki if your team writes long briefs.

5. SiYuan: local-first docs with databases and AI chat

SiYuan is an AGPL-3.0, local-first note and knowledge app with block references, Markdown editing, databases inside documents and end-to-end encrypted sync. Its README lists AI writing and question-and-answer chat through the OpenAI API, so you can point it at a provider of your choice. Most features are free, even for commercial use, and some are for paying members. It is built for individuals more than teams: the Docker version gives browser access only. Version 3.8.9 came out in October 2026.

6. Docmost: a team wiki, with AI on the paid plan

Docmost is an open-source wiki for teams with real-time collaboration, spaces, permissions, full-text search and Notion import. The free, self-hosted Community edition has its core features, but the Docmost pricing page puts AI, MCP, Kanban and Bases (databases) on the Business plan at $6 per seat per month billed annually, with a minimum of 10 seats. Choose it when your Coda docs are mostly handbooks and team pages rather than trackers. Version 0.97.0 came out in October 2026.

7. Teable: database tables with AI and an app builder

Teable is an open-source database with a spreadsheet interface. Its Community Edition is AGPL-3.0 and free to self-host. The project lists AI chat, an App Builder, AI steps in automations and AI field filling, and says self-hosters can use their own models and keys. Read the setup first: the Standalone install has no AI and no App Builder, and in the official image the AI features are unlocked with a paid licence key. Teable publishes new builds almost daily.

Coda Alternatives That Are Not Open Source, and Old Picks We Removed

These tools often appear on open-source Coda lists, but their licences limit what you may do with them:
  • NocoBase: a strong no-code platform with AI employees that analyse data, fill forms and route tasks. Its licence is Apache-2.0 plus supplementary terms that forbid removing NocoBase branding and offering it to the public as a no-code or AI SaaS, so it is not strictly open source. It builds apps rather than docs; see our open-source Retool alternatives.
  • NocoDB: its licence file, updated in January 2026, now uses the Sustainable Use License, which allows use only for internal business, non-commercial or personal purposes. It is source-available, not open source.
  • Anytype: local-first and end-to-end encrypted, but its app uses the Any Source Available License, not an open-source licence.
  • Outline: a polished team wiki under the Business Source License 1.1, which becomes Apache 2.0 only years after each release.
The 2025 version of this article also listed tools that do not replace Coda. OpenProject, ProjectLibre, Taiga and GanttProject are project management tools; we compare them in open-source monday.com AI alternatives and open-source Trello AI alternatives. OnlyOffice Docs is an office suite, PostgreSQL is a database server and HeidiSQL is a SQL client, so none of them gives you Coda's docs with tables. ToolJet builds internal tools, and its AI features sit in the paid edition. The old article's FAQ links went through Google search redirects, which we removed.

Which Open-Source Coda AI Alternative Should You Choose?

  • You want docs and databases together, like Coda: AppFlowy, or AFFiNE if you also plan on whiteboards.
  • Your Coda docs run on formulas: Grist, with its AI Formula Assistant pointed at your own model.
  • You built apps and automations in Coda: Baserow, or NocoBase if its licence terms are fine for you.
  • You want AI without sending data to a cloud: Grist or Baserow with a local model, AFFiNE with your own key, or AppFlowy with self-hosted LLMs.
  • Your docs are mostly a company wiki: Docmost, adding the Business plan only if you need AI.
  • You work alone and value privacy: SiYuan.

We have checked open-source Notion AI alternatives, open-source Notion alternatives without the AI focus, open-source Airtable AI alternatives and open-source Airtable alternatives for databases, open-source Obsidian alternatives and open-source Roam Research alternatives for personal notes, and open-source AppSheet alternatives for no-code apps. Since Coda now sits in the same suite as Grammarly, our open-source Grammarly alternatives may help too.

How Founders Use an Open-Source Coda Replacement

For an early-stage startup, a Coda-style workspace is the operating system of the company: the strategy doc, the hiring tracker, the investor list and the weekly metrics live in one place. Start with three pages: a company wiki, one tracker table for your current goal and a meeting notes template, and add AI only where it saves time, such as summarising notes or filling a column. If customer or investor data goes into the workspace, self-hosting with your own or a local model keeps it out of third-party AI services. Replace Coda's automations and Packs with open-source Zapier alternatives, and read about the hidden costs of no-code AI development before you build internal apps on any platform.
Before you build anything, validate your startup idea with real customers, and turn the knowledge in your wiki into articles with the F/MS AI SEO Tool so customers find you in Google and AI assistants.

FAQ About Open-Source Coda AI Alternatives

What is the best open-source alternative to Coda AI?

AppFlowy is the closest match: docs and databases in one workspace with AI for writing, chat, search and meeting notes, and support for self-hosted models. Choose Grist instead if Coda's formulas are what you use most.

Is Coda still available?

Yes, under a new name. Coda was renamed Superhuman Docs on 8 July 2026, existing docs moved over automatically, and coda.io now points to Superhuman's pages.

Who owns Coda now?

Grammarly announced the purchase of Coda in December 2024, and the company now uses the Superhuman name for its suite of Grammarly, Superhuman Mail, Superhuman Go and Superhuman Docs.

How much does Coda AI cost in 2027?

When we checked in October 2026, Superhuman Docs Pro cost €12 per Doc Maker per month billed annually and Business €33, with AI in beta for Doc Makers. The Free plan includes a trial of Docs AI.

Which open-source Coda alternative works with a local AI model?

Grist and Baserow can connect to local or self-hosted models (Baserow lists Ollama), AppFlowy supports self-hosted LLMs, and AFFiNE accepts your own API key and, if the admin allows, custom OpenAI-compatible endpoints.

Is there an open-source tool with formulas like Coda?

Grist. Its formulas are written in Python, with many Excel functions available, and its AI Formula Assistant writes formulas for you.

Is NocoDB still open source?

No. Its licence file, updated in January 2026, uses the Sustainable Use License, which limits use to internal business, non-commercial or personal purposes. Baserow and Grist are open-source alternatives.

Is AppFlowy free to self-host?

The apps are open source, but the self-hosted server is now a closed-source commercial build whose free tier covers one user seat and up to 3 guest editors. For a larger team, compare AFFiNE's free self-hosted edition or Docmost Community.

Can an open-source tool replace Coda Packs?

Partly. Baserow and Teable have built-in automations, Grist and Baserow have APIs, and an open-source automation tool can connect them to your other apps. Check that the integrations you use most have an equivalent before you move.

Where can I get a backlink by writing about my startup?
